'''Double-Edge Dance''' ({{ja|マーベラスコンビネーション|Māberasu Konbinēshon}}, ''Marvelous Combination'') is [[Roy]] and [[Chrom]]'s [[side special move]].

It is a variation of [[Marth]]'s [[Dancing Blade]] (with which it shares its Japanese, Chinese and Korean name), and has the same general behavior; however, one major difference as a result of the user's faster falling speed is that it does not stall the user in the air as effectively. Another major difference is that Roy's Double-Edge Dance has a [[flame|fire]] effect on the last hit (in ''Melee'', this also applies to the third hit when inputted downwards).

===In ''[[Super Smash Bros. Melee]]''===

The first two hits of the four-hit combo are relatively weak and easily [[crouch cancel]]ed by opponents, but they will come out no matter how quickly they are inputted. For the third and fourth hits, the player must wait a few frames between inputs, or else the attacks will not come out. The tradeoff for the difficulty in inputting the later hits is significantly higher knockback, which can knock over opponents trying to crouch cancel.

The third hit of the combination inputted upward has a [[meteor smash]] hitbox, producing a slightly diagonal trajectory if the sourspot does not hit. On grounded opponents, it will knock them into the air and set up for the fourth hit. Inputted forward, the third hit deals excellent knockback and can be used as a [[KO]] move at higher percentages. The third hit inputted downward produces a [[flame]] effect and can knock over opponents trying to [[crouch cancel]]. Unusually, while the third hit forwards has higher base knockback, its growth is actually smaller than Dancing Blade's version, meaning it is overall less powerful at higher percentages, while also being harder to link the fourth hit together with the third hit at lower percentages.

With the exception of the downward input, the final hits of DED deal the most knockback compared to the other hits. The upward input has high vertical range and high knockback. The down input deals multiple hits, and while it deals little knockback, its long range and duration make it effective for [[shield stab]]bing and knocking down opponents attempting to crouch cancel. Compared to the other inputs, the forward one is lackluster, and rarely used.

===In ''[[Super Smash Bros. 4]]''===

Double-Edge Dance returns in ''SSB4'', where it has been updated to use Marth's Dancing Blade animations from ''Brawl'' and ''SSB4'', making it one of Roy's only attacks that has not gained an animation distinct from Marth. Its many attacks have gained different attributes when compared to ''Melee'', making its hits essentially the same as Marth's version.

Some of the unique attributes of Double-Edge Dance have now been removed: the third hit no longer acts as a flame-infused strong hit, and now chains into the fourth hit, which acts as the finisher. Additionally, all angles of the first three swings now connect into the ending hit. Like Dancing Blade, it is now an integral move for damage-racking, catching landings and shield-pressuring when the opponent is close.  

As Roy shares Marth's technical changes from ''Melee'' to ''SSB4'', Double-Edge Dance now requires less technical precision to input in a row which makes the attack easier to combo, but suffers from similar issues with connecting together at higher percentages.

As with Dancing Blade in ''Brawl'' and ''SSB4'', the first hit stalls Roy's movement in the air for a few frames, although unlike the aforementioned move, it does not make Roy lose his momentum as much, due to his faster falling speed. This makes this unusable for recovery in comparison to Marth's when combined with his aforementioned falling speed, but makes it a better approaching air-to-ground attack.

Double-Edge Dance returns as Roy's side special move in ''Ultimate''. Much like in ''SSB4'', Double-Edge Dance has received many of the same adjustments as Marth's Dancing Blade: each swing transitions significantly faster and can be [[buffer]]ed, and all hits have altered animations. Most infamously of all, however, the final neutral hit of Roy's Double-Edge Dance deals noticeably more knockback when sweetspotted, improving its already-impressive KO potential. On the other hand, the first swing has higher startup, making it easier to predict.

As Roy's Echo Fighter, the basic properties of {{SSBU|Chrom}}'s Double-Edge-Dance are identical, including its frame data and aerial stalling ability. However, as Chrom's [[list of swords#Falchion|Falchion]] lacks a sweetspot and sourspot, his version of Double-Edge Dance deals consistent damage and knockback. While the fourth forward swing of Chrom's move deals much more damage and knockback than Roy's sourspotted move, it still deals considerably less knockback than Roy's sweetspotted variant, hindering its KO potential compared to Roy's. All three variations of the final hit also lack flame properties as well. Because of these differences, his version is much closer in appearance and function to {{SSBU|Lucina}}'s Dancing Blade, but is slightly stronger than hers.
