'''Leffen''' is a professional smasher from Stockholm, Sweden. He is currently considered to be one of the best ''[[Melee]]'' players in the world along with {{Sm|Hungrybox}}, {{Sm|Mango}}, {{Sm|Axe}}, {{Sm|Wizzrobe}}, {{Sm|Zain}}, {{Sm|aMSa}}, and {{Sm|Plup}}. He started off as a {{SSBM|Falco}} main, but later switched to {{SSBM|Fox}}, and is now known as one of the most technical Fox players in the world and the best Fox player in the world. He is the first of only two players in competitive ''Melee'' history to have taken a set off of each of the [[Five Gods]] (the other being Plup), and has often been called a god himself since his ascent in 2014. Leffen is ranked 1st on the [[European Melee Power Rankings]], 2nd on the [[2019 MPGR]], and 1st on the [[Swedish Power Rankings]].

Although Leffen didn't play ''Brawl'' or ''Smash 4'' competitively, he has been active in ''[[Ultimate]]'' playing {{SSBU|Pokémon Trainer}} and is considered one of the best Pokémon Trainer players in the world, along with {{Sm|Ned}} and {{Sm|Pandarian}}. Leffen has defeated players such as {{Sm|Tweek}}, {{Sm|Salem}}, {{Sm|WaDi}}, {{Sm|Puppeh}}, {{Sm|Mr.R}}, {{Sm|Maister}}, {{Sm|ZD}}, and {{Sm|8BitMan}}. He is currently ranked in Area 51 on the [[Fall 2019 PGRU]].

==Tournament history==
===Early career===
Leffen's introduction to ''Smash'' was through ''[[Brawl]]'', which he played online in 2009.

In 2010, he started attending tournaments for ''[[Melee]]''. He mained Falco and also trained a Yoshi secondary, which he used to great success at Stockholm locals and at Danish events.

Leffen's first stateside outing was at [[GENESIS 2]]. After defeating {{Sm|SFAT}} in pools, he went on to lose to SFAT and {{Sm|S2J}} in bracket to place 17th.

[[Apex 2012]] was Leffen's first serious event as a Fox main. Leffen reached bracket, then lost a last-hit set to {{Sm|Mew2King}} in winners. He went on to lose his next set to {{Sm|Teczer0}}.

Throughout the course of 2012, Leffen established himself as Europe's second strongest player, with key results at [[Smashers' Reunion: Melee Grande]] and at [[hf.lan 4]]. He sparred often with Armada, making headway but never taking a set. He came closest at an unrecorded local in December, where he was leading winners' finals 3-2 (in a best-of-7) and brought the sixth game to last stock before Armada clutched out the victory, going on to win the set 4-3.

At [[Apex 2013]], Leffen defeated {{Sm|MacD}} and {{Sm|Cactuar}} in winners to meet {{Sm|Hungrybox}}. He made a splash by bringing Hungrybox to last hit, but would lose this set as well. This close loss would go on to inspire a [[Salty Suite]] rematch the following year. In losers, Leffen immediately lost another last-hit set, this time to {{Sm|JAVI}}, who himself had dropped into losers early due to a pools loss to {{Sm|ESAM}}.

Soon thereafter, Leffen was banned from many European tournaments by a group of organizers and Smashers, largely led by Armada (discussed in greater detail [[Smasher:Leffen#Controversy|here]]). He attended only three more events for the rest of the year. He traveled to [[Evo 2013]], defeating {{Sm|PewPewU}} before losing again to {{Sm|Hungrybox}}, this time without taking a game, and to {{Sm|Shroomed}} in losers to place 9th. He and {{Sm|Ice}} scored an upset victory in doubles against eventual victors {{Sm|Mew2King}} and {{Sm|Hungrybox}}; the European team would go on to place 5th.

Leffen also attended a NYC local in September called CFST: Warzone 2 where he suffered unusual losses to {{Sm|MattDotZeb}} and {{Sm|G$}}, perhaps due to lack of practice. He finished out the year at the French [[hf.lan 6]] where he placed second, defeating {{Sm|Baxon}} and {{Sm|Salepate}} convincingly before losing two close sets to {{Sm|Ice}}. Given his powerful play despite his scarce results, Leffen was ranked 14th on the [[2013 SSBMRank]].

Leffen's ban ended early in 2014, allowing him to compete in Europe again.

===Emergence as a top 6 player===
On day 1 at [[Apex 2014]], Leffen and {{Sm|Hungrybox}} played in a [[Salty Suite]] set, which Hungrybox won 3-1. In bracket, Leffen defeated {{Sm|Darrell}}, {{Sm|Scar}}, and {{Sm|Axe}} before finally taking revenge on {{Sm|Hungrybox}} 2-1 in winners' quarters to reach top 8 and earn his first win over one of "the [[Five Gods]]". He went on to lose to {{Sm|Mew2King}} 1-3 in winners' semis. He eliminated {{Sm|Colbol}} 2-0 in losers' quarters, and then had a close and intense set with {{Sm|Mango}} in losers' semis, but was ultimately eliminated 2-3. This 4th place showing immediately confirmed Leffen as a player to watch for the rest of the year and would presage his ascent to godhood.

Leffen won his first European national at [[B.E.A.S.T 4]], which was also his first European tournament after his ban was lifted. He lost to {{Sm|Ice}} 2-3 in winners' semis, but then eliminated {{Sm|Fuzzyness}} 3-0 in losers' quarters, {{Sm|Overtriforce}} 3-1 in losers' semis, and Ice 3-2 in a rematch in losers' finals. In grand finals, he managed to win two sets against {{Sm|Armada}}, 3-0 and 3-1, respectively. This marked his second "god" victory. Later, Leffen won [[Republic of Fighters 3]], qualifying for the [[MLG Anaheim 2014]] championship bracket. He defeated Ice 3-1 in winners' semis, but lost to Armada 0-3 in winners' finals. After eliminating {{Sm|aMSa}} 3-2 in losers' finals, he came back and won 6-0 against Armada in two best of 5 sets.

In his pool at MLG Anaheim 2014, Leffen defeated {{Sm|PPMD}} 3-2 (the third "god" he had beaten), {{Sm|Axe}} 3-1, Colbol 3-1, {{Sm|s0ft}} 3-0, and {{Sm|Remen}} 3-0, but lost to Mew2King 1-3 and {{Sm|Hax}} 2-3. Seeded in losers' bracket in the championship bracket, he defeated both {{Sm|Westballz}} and Hax 3-2, before losing to PPMD 1-3 in losers' quarters, placing 5th overall. At [[EVO 2014]], Leffen defeated {{Sm|Lambchops}} 2-1, {{Sm|OkamiBW}} 2-0, and {{Sm|S2J}} 2-0 in the winners' quarters pools, but lost to Mew2King 0-2. In losers' bracket, he was eliminated by {{Sm|Silent Wolf}} 1-2, finishing off at an underwhelming 9th place overall.

At [[COMEBACK I]], Leffen defeated {{Sm|Android}} 3-0 in winners' semis to make it to winners' finals against Armada, in which he lost 1-3. After defeating Android 3-1 in losers' finals, he lost again to Armada in grand finals, this time 2-3, placing 2nd in ''Melee'' singles. Leffen also won ''Melee'' doubles with {{Sm|Beat}}, defeating {{Sm|Dev}} and {{Sm|Kuja}} 3-1 in winners' semis, Android and {{Sm|Zoler}} 3-1 in winners' finals, and Armada and {{Sm|C|p=Sweden}} 3-1 in grand finals.

At [[The Big House 4]], Leffen defeated Hungrybox 3-2 in winners' quarters to advance to winners' semis. He then faced off against Armada in another close set, ultimately managing to clench out a victory 3-2 and advance to winners' finals for the first time at an American national. However, he lost 0-3 to Mew2King in winners' finals and 1-3 to Mango in losers' finals, with a 4-stock by Mango to close out the set.

At [[B.E.A.S.T 5]], Leffen managed to solidly defeat Armada 3-1 in winners' semis to advance to winners' finals. He managed to take his first victory over Mango in a 3-2 set to advance to grand finals, where he would once again face Armada. Despite a closely fought set from both players (with Armada notably 4-stocking Leffen in game 4), Leffen managed to win grand finals 3-2, earning his first national victory with at least two of the [[The Five Gods|"gods"]] present.

After this 1st place finish at a major, there was one achievement left before Leffen could indisputably be considered in the same tier as the "gods": defeating Mew2King, the only one he had not beaten. 

This set the stage for [[Apex 2015]], the [[List_of_largest_Smash_tournaments#Super_Smash_Bros._Melee|largest ''Melee'' tournament in history at the time]], where all five "gods" were present, and where Leffen and Mew2King were seeded to play in winners' quarterfinals. After beating {{Sm|Larry Lurr}} and aMSa in top 48, Leffen made it to Mew2King. In a momentous 2-1 victory, including a dominant 3-stock on game 3, Leffen defeated Mew2King, becoming the first player to take a tournament set from all five "gods" of ''Melee''. He then went on to face Mango in winners' semifinals; Leffen beat Mango once again, 3-1, to advance to winners' finals and prove that his previous victory was no fluke. Looking poised to take the tournament, Leffen then fell to PPMD 2-3 and Armada 1-3, earning 3rd place. He outplaced three of the five "gods" and cemented himself as one of what was now the "top six," a player able to beat any other ''Melee'' player and take major tournaments. As the "Five Gods" is a historical term, the community gave Leffen the title of "Godslayer."

Leffen continued to develop as a top-level threat. At [[CEO 2015]], Leffen earned 1st in singles--his first American national victory. He had a close set with {{Sm|Plup}} in winners' quarters but ultimately won 2-1, and proceeded to sweep the rest of the tournament, beating {{Sm|Shroomed}} 3-0 and Armada twice in winners' finals and grand finals; each set was 3-0 and 3-1, respectively. In doubles, Leffen teamed with Hungrybox, placing 2nd; they had managed to trade sets with {{Sm|PewPewU}} and {{Sm|SFAT}} and take a set off of Armada and Shroomed, but they ultimately lost a close second set 2-3.

At [[FC Smash 15XR: Return]], Leffen earned 1st in singles. He defeated {{Sm|Swedish Delight}} 3-0 in winners' quarters, he then beat Hungrybox 3-1 in winners' semis and Armada 3-1 in winners' finals, including a 4-stock in game 1 on Final Destination. In grand finals; he met Hungrybox once again and beat him 3-1.

Leffen once again got first place at [[WTFox]] singles, including an impressive 3-0 victory over Mang0's Falco in grand finals, making three consecutive first place finishes in singles. At this point, Leffen looked dominant--a favorite to take future major tournaments.

However, he failed to repeat this success at [[EVO 2015]], being sent into losers by Hungrybox, and then eliminated at 5th place by Plup's Samus.

At [[Super Smash Con 2015]], Leffen bounced back and took first place once again in singles, beating Mew2King 6-1 collectively in winners' finals and grand finals. Mew2King answered back in their next meeting at [[PAX Prime 2015]], where Mew2King took the tournament with a collective 6-0 victory over Leffen.

Leffen once again failed to capture first place at [[Paragon Los Angeles 2015]], being sent to losers by Mew2King, and being eliminated by Hungrybox, ending another tournament run at 5th place.

At [[HTC Throwdown]], Leffen made it to Grand Finals from the winners side, where he defeated Hungrybox in grand finals 3-0.

Leffen's reign of dominance was cut short, however. He was unable to enter [[The Big House 5]], [[Smash Summit]], [[GENESIS 3]], [[Battle of the Five Gods]], and [[Smash Summit 2]] due to international visa issues. Furthermore, he was denied a worker's visa from the United States, primarily for reasons that question ''Melee''{{'}}s legitimacy as a sport. [https://www.youtube.com/watch?v=MdVejIOYp-M The video showing the rejection letter] started a movement to reverse the decision. Eventually, Leffen came to be temporarily allowed into the USA up until and throughout July 2016, tentatively letting him attend [[EVO 2016]].[http://tsm.gg/index.php/news/leffen-visa-update/] Due to his visa going through additional processing resulting from his deportation from the US however, Leffen was ultimately unable to attend EVO 2016.

During his American visa issues, he notably won ''Melee'' singles at [[Get On My Level 2016]], after beating Mew2King 3-2, Armada 3-1, Hungrybox 3-2, and Mango 3-1 without losing a set.

Leffen's visa was finally accepted on October 3rd, 2016, allowing him to compete in the US again. Since then, he has remained a steady top-level threat, but has not reached the same dominance as in 2015 before his visa issues.

After many years of coming close to the top and failing in the [[EVO|Evolution Championship Series]], Leffen finally took 1st place in the Grand Finals of [[EVO 2018]] for Super Smash Bros. Melee.

===Other ''Smash'' games===
Leffen also played ''[[Project M]]'' at a high level for a while, and was known as one of the best players of {{PM|Captain Falcon}}, {{PM|Fox}}, and {{PM|Zero Suit Samus}}.

Leffen has occasionally played ''[[Smash 4]]'', and notably pioneered the usage of {{SSB4|Diddy Kong}}'s up throw to up air combo.

Leffen often streams ''[[Super Smash Bros. Ultimate]]'' and offers his own opinion on the meta. He was one of the early pioneers of using {{SSBU|Pokémon Trainer}} and has used the character in a few tournaments, including {{Trn|Valhalla II}} and {{Trn|GENESIS 6}}, where he placed 7th and 17th, respectively, and defeated players such as {{Sm|Seagull Joe}} and {{Sm|WaDi}}. Leffen initially dropped Pokémon Trainer in favor of {{SSBU|Roy}} and {{SSBU|Pichu}}, citing that Pokémon Trainer was not worth the effort, but he would eventually go back to playing Pokémon Trainer. Leffen also began playing Joker upon his release and discovered the [https://www.youtube.com/watch?v=nFDh3c_6JmI "Leffoble"], where Joker could trap opponents by fast falling an up air repeatedly while the opponent was on a platform. Leffen then semi-retired from ''Ultimate'' singles, mainly citing the smaller scene in Sweden and issues with online play making it difficult for him to get any meaningful practice. He has stated he may still enter singles for the game in the future but has since stopped practicing for the game [https://twitter.com/TSM_Leffen/status/1120003964995551234]. 

The release of {{SSBU|Hero}} saw him continue playing Ultimate, and he intended to compete in {{Trn|EVO 2019}}, but issues with his visa kept him from doing so. Leffen has continued to enter for both ''Melee'' and ''Ultimate'' at major tournaments such as {{Trn|Super Smash Con 2019}}, but he puts more importance towards ''Melee''. He has many successes in ''Ultimate'', with set wins over {{Sm|Tweek}}, {{Sm|Salem}}, and other top players. Following his first place at {{Trn|DreamHack Winter 2019}}, Leffen announced he would once again be putting ''Ultimate'' on the backburner, instead focusing on ''Melee'' and other fighting games.

==Playing style==
Leffen is the best solo Fox main in the world; he has consistent execution and movement, and boasts solid fundamentals in all aspects of the game, using a methodical and efficient approach, making him a very well-rounded player. Leffen has both a great [[neutral game]], as he rarely overextends or overreaches in games even against weaker opponents, and a solid [[combo]] game, especially against fastfallers. He is renowned for his proficiency against {{SSBM|Falco}}, {{SSBM|Peach}}, and other Foxes, having made his first upsets against the [[Five Gods]] in those matchups. Leffen's prowess against Peach is so great that even {{Sm|Armada}}, the best Peach in the world, would always opt for the Fox [[ditto match|ditto]] in tournament instead.

While Leffen is well-rounded, he undoubtedly focuses on the mental game and adaptation more than technical play. Leffen has once stated in an interview that he believes many high-level players are held back by "flowchart" behavior that he is able to exploit. This is clearly exemplified by his ability to "clutch" out sets from losing positions, even from 0-2 deficits. Despite this, he still puts in the work to lab certain matchups or situations that give him trouble, showing his solid work ethic; he's even known to lab other miscellaneous characters solely to push the metagame forward. Along with Armada, he practices with {{Sm|Snowy}} for the Jigglypuff matchup, and has flown him out to events such as Summit in order to prepare for facing Hungrybox in bracket.

Prior to his establishment as a top 5 player, Leffen had noticeable trouble against punish-heavy players. Despite his strong fundamentals, he struggled if his opponent could overwhelm him technically, leading to losses against {{Sm|Silent Wolf}}, {{Sm|Westballz}}, and {{Sm|Javi}}, among others. He also could not defeat {{Sm|Mew2King}} for a long time, even after he had upset the rest of the Five Gods, because of that aforementioned weakness. Leffen was also noted to be fairly poor at the {{SSBM|Samus}} matchup, having, at one point, losing records with {{Sm|HugS}} and {{Sm|Duck}}, both of whom are considered far below his skill level. He has also lost three times to {{Sm|Plup}} in solo Samus sets. However, he has since overcome these weaknesses and no longer drops sets as frequently to these types of players, most notably not having lost to solo Samus since 2018.

==Controversy==
Despite being considered one of the best professional smashers in ''Melee'', Leffen has led a controversial career as a smasher, due to his previously rude conduct during and outside of tournaments. Several players, most of which were new smashers to the scene, accused him of:
*deliberately [[sandbagging]] in pools by playing low tier characters while insulting his opponent's skill throughout and after the match.
*spreading exaggerated rumors about others, making rude and provocative comments on [[SmashBoards]], and deliberately starting arguments with users.
*further blaming other people when confronted about his actions, using his status as a top professional player to decrease his punishments.

After noticing his poor behavior, Swedish tournament organizers and other ''Melee'' professionals of his caliber gave him repeated warnings concerning his attitude. In August 2012, Leffen was eventually threatened with a ban from tournaments if he did not improve his attitude, but he did not take the claim seriously. This led to further discussions among the European ''Smash'' community that culminated in his [http://www.smashboards.com/threads/leffen-is-banned.333990/ national ban from Swedish tournaments], effective February 9th, 2013.

The discussion group announcing his ban compiled a significant amount of evidence of his poor behavior into a downloadable archive, and demanded that Leffen create a lengthy apology about all of his wrongdoings and how he would change his behavior in the future, should he return to the community. On March 21st, 2013, [http://www.twitlonger.com/show/n_1rjbt3e Leffen made his public statement asking for forgiveness]; despite this, he was not immediately unbanned, and ended up missing almost one year's worth of local tournaments. On January 24th, 2014, it was announced by {{Sm|Armada}} that the Swedish ban on Leffen was no longer in place [https://www.facebook.com/events/182185045312694/permalink/206413366223195/?stream_ref=2]. His conduct since then has since improved dramatically, but he still remains a relatively controversial figure in the community, especially on social media sites such as Reddit and Twitter, due to his blunt comments.

At [[Heir II the Throne]], Leffen was banned from commentary on all future European Smash Circuit events for saying that it wasn't a "serious" tournament and players were playing their secondaries and not trying. Leffen notably compared the tournament to [[The Foundry]], a series notorious for its relaxed and non-competitive atmosphere. Many argued that the TOs had overreacted in their decision, and that a full ban was an excessively harsh punishment.

During top 8 of Shine 2017, {{Sm|ChuDat}} narrowly beat Leffen 3-2 getting a reverse 3-0 on him, ending Leffen's run at 7th. It was later discovered that the set had been played on vanilla Melee instead of with [[UCF]] enabled, a mod designed to make shield dropping and dash back consistent rather then RNG based. The set would be controversially replayed, resulting in a 2-3 victory for Leffen, ending ChuDat's run at 7th. Leffen would receive backlash from this, although the decision had been made by the Shine TOs; many agreed that Leffen should not have received such negative attention for the ruling, as the TOs had created the situation by failing to check that UCF was turned on.

==Trivia==
*Outside of ''Smash'', Leffen formerly was a professional ''Dragon Ball FighterZ'' player, being arguably the best DBFZ player in Europe, and is currently ranked 14th on the [[Panda Global]] Rankings Z. He frequently streams ''Dragon Ball FighterZ'' and entered multiple ''Dragon Ball'' tournaments, placing very well. He has retired from competing in the game, citing Toei’s meddling in tournaments, and Arc System Works' way of patching as the two reasons he does not enjoy the game anymore.
**Leffen is currently the only ''Smash'' player to have been invited to a non-''Smash''-related Summit event ([https://smash.gg/tournament/summit-of-power/events Summit of Power]).
*At {{Trn|Apex 2015}}, Leffen defeated {{Sm|Mew2King}} in tournament for the first time in his career, which marked Leffen as the first player to have won at least one tournament set against each of [[The Five Gods]] (having previously defeated {{Sm|Hungrybox}} at {{Trn|Apex 2014}}, {{Sm|Armada}} at {{Trn|B.E.A.S.T 4}}, {{Sm|PPMD}} at {{Trn|MLG Anaheim 2014}}, and {{Sm|Mango}} at {{Trn|B.E.A.S.T 5}}). He would remain the only player to hold this distinction until {{Sm|Plup}} defeated Armada at {{Trn|The Big House 7}}.
*At Apex 2015's Salty Suite exhibition, Leffen won a $100 [[money match]] 5-0 against {{Sm|Chillin}} in {{SSBM|Fox}} [[dittos]]; Chillin was also forbidden from using Fox's [[Alternate costume (SSBM)#Fox|default costume]] in future tournaments. However, at [[The Big House 6]], Leffen allowed Chillin to use the costume again.
**After Leffen won {{Trn|EVO 2018}}, Chillin humorously tweeted out that "Leffen confirmed no longer has to show his elders some respect"
*Leffen is commonly considered a villain in the ''Smash'' community due to his reportedly rude behavior and trash-talk. He claimed that he enjoys his given title due to the community's need of someone to root against, although a controversy exists over whether he should embrace it or not.
**Ironically, his surname is Swedish for "hero".
*At [[FC Smash 15XR: Return]], Leffen became the first player to four stock {{Sm|Armada}} in bracket, in game 1 of winners finals on {{SSBM|Final Destination}}. He would repeat this feat at [[Smash 'N' Splash 4]] in game 4 of winners semis on [[Yoshi's Story]] to close out the set, marking only the second time Armada has been four-stocked in bracket.
*Leffen, along with {{Sm|Tafokints}}, holds the title of the most money won in a single money match, a title which he earned at Apex 2015 when he defeated Mango in a $1,000 money match. At [[DreamHack Winter 2015]], he defeated {{Sm|SFAT}} 5-1 in another $1,000 money match. On June 10th 2019, at The Kid, the Goat, the Mang0, Leffen and Mango bet $1,000 on a loser's quarter-finals match between {{Sm|Lucky}} and {{Sm|Swedish Delight}}, with Leffen betting on Swedish, and Mango voting on Lucky. Swedish Delight would go on to win the set.
*Leffen decided not to compete seriously at The Big House 6; he instead used his secondaries {{SSBM|Falco}} and {{SSBM|Marth}} to place 17th, losing to {{Sm|Gahtzu}} and Swedish Delight.
*Leffen donated the prize money he won at [[B.E.A.S.T 7]] to multiple charities.
*Leffen is infamous for a spate of losses against {{SSBM|Samus}} players {{Sm|HugS}}, Plup, and {{Sm|Duck}} in 2015 and 2016 after having mocked Chillin's losses to the same character on Twitter.
*Leffen is sometimes referred to by his nicknames ''Big Leff'' or ''Yung Leff''. When he is losing in tournament, he may also, by effect, be referred to as ''Small Leff'' or ''Minuscule Leff''.
**He has also been referred to these names by ''Dragon Ball FighterZ'' commentators.
*Leffen has gotten into scuffles with {{Sm|Salem}} on Twitter, originating in December of 2018, with the two taking shots at each other on Twitter, with Salem mocking Leffen's skill at ''Ultimate''.  
**The two were scheduled to meet in bracket at multiple tournaments but never did due to upsets and DQs. They finally met in bracket at {{Trn|Super Smash Con 2019}}, where Leffen beat Salem 2-1.
