Editing Duon

{{disambig2|the Subspace boss|the Australian smasher|Smasher:Duon}}

'''Duon''' ({{ja|デュオン|Dyuon}}, ''Duon'') is the sixth [[boss]] encountered in [[The Subspace Emissary]]. He doesn't hail from any particular series, and is unique to ''[[Super Smash Bros. Brawl]]''. He is created by several [[Shadow Bug]]s that have gathered in a single, very powerful being.

His name is derived from the Latin word ''duo'', a word meaning ''twosome'', or a group of two, alluding to his two-faced design.

Duon is a two-sided robot on one set of wheels; one half is pink and has a head cannon and two arm cannons, and the other half is blue with two arm swords and a curved blade on his head. Both sides have shoulder exhaust pipes which rockets (pink side) or mines (blue side) can be fired from (though these can also be fired from the arm cannons). He rotates 180 degrees to change his attack strategy. The wheels he pivots on loosely resembles the Yin and Yang. There is an invisible platform between Duon's two halves, making Duon one of only two bosses that a character can actually stand on, the other being [[Porky Minch]].

After {{SSBB|Snake}}, {{SSBB|Lucario}}, and {{SSBB|Meta Knight}} kick all the {{SSBB|Mr. Game & Watch}}es out of the Halberd's control room, they fall to the bridge and dissolve into [[Shadow Bug]]s, which form into Duon, a last resort to defend the Halberd. The monster is confronted by Snake, Lucario, {{SSBB|Fox}}, {{SSBB|Zelda}}/{{SSBB|Sheik}}, {{SSBB|Peach}}, and {{SSBB|Falco}} (Meta Knight stays behind to retake his ship and does not take part in the fight). The boss battle makes up the entirety of the [[Battleship Halberd Bridge]] level. After Duon is defeated, it dissolves into Shadow Bugs and leaves behind the trophy of Mr. Game & Watch.

Like all bosses Duon is controllable with hacks in [[Boss Battles Mode]]. The start button self-destructs any boss, while using [[Grapple Beam]] resets them to AI control.

| Head Sword Chop || A || Duon bashes its head forward with high speed and immense knockback. Knockback can be both vertical and angled, depending on how it lands; if the player stands on Duon, the hit always lands. In general this move is swift and unpredictable, but suffers from a very short [[range]]. || Blue

| Jump Crash || A^ || Duon jumps up high and crashes down, then grinds in place (prevents close-range attacks). The jump goes farther across the field on higher difficulties, which, ironically, makes it easier to avoid. If the player is hit by Duon in the fall, they will sustain enormous vertical knockback. Damage can reach 62%. If the player stands on Duon during this move, they will be inflicted vertical knockback with high KO power just before the jump lands. Being hit while midair also increases the KO potential. || Both

| Vacuum Spin || Av || Duon spins around with a very strong [[vacuum]] effect (although the range is quite short). It is extremely difficult for the player to escape once they have been trapped by the spin. If all hits chain on Intense, the move will deal up to 84% damage in around three seconds. It also pushes down the character if they are below the ledge, effectively negating many non-tether-based recoveries and gimping many fighters. Also, if the player stands on Duon, they will always be sucked in by the attack, suffering the maximum damage and knockback. || Both

| Sword Blast || A< or A> || Duon readies its arms shaping a cross, then slashes making a large shockwave in front of him. The hit itself deals strong knockback. Damage is also very high, however the slash itself has a very low range. The red shockwave inflicts high knockback, but is not as strong. In Boss Battles, it won't KO until noticeably later, but is still powerful. Its hitbox is also very large.|| Blue

| Mines || B || Duon launches several mines in the air. These can be detonated (but won't hurt Duon) with vertical-based attacks, such as {{SSBB|Pikachu}}’s [[Thunder]] or a chucked item. It is always followed by a "shared attack". The mines are quite difficult to avoid, despite being slow, but they are also one of Duon’s weakest attacks, KOing at relatively high percentages (over 100% on the lower difficulties and around 75% on Intense). Knockback is perfectly vertical, while damage reaches around 30% for each hit on Intense. The higher the difficulty, the more mines are launched. || Blue

| Homing Missiles || B^ || Duon moves its non-weapon arm back to shoot four homing missiles. The missiles can be directed to hit Duon itself, inflicting very high damage. On lower difficulties in Boss Battles, all four missiles redirected to Duon can nearly KO the boss. The missiles can be detonated with vertical-ranged attacks or thrown items. They can damage Duon even if the explosion hits it. It is always followed by a "shared attack". The missiles are very powerful, inflicting up to 30% with enough power to KO under 50% on Intense difficulty. The higher the difficulty, the more accurate the homing is. || Pink

| Blue Bolts || Bv || Duon's head glows, and then shoots three strong blue bolts that will pierce though everything (including the field and Duon, but it doesn't hurt himself) except {{SSBB|Pit}}'s [[Mirror Shield]]. At higher difficulties, they will break shields, so dodging is preferable, although difficult. They cannot be reflected or absorbed. Touching the blue sphere on Duon's head deals very high vertical knockback. The beams themselves are extremely powerful, being able to KO around 30% and inflicting high damages (up to 35%). The beams' high speed and piercing ability, as well as the unpredictable beginning, make this attack extremely dangerous. || Pink

| Vertical Pink Shots || B< || Duon shoots pink lasers with a vertical-spread coverage. Can be [[reflect]]ed or [[absorb]]ed. It will aim higher and a little back if above or behind Duon. Each laser projectile (around twelve shots in a row) deals up to 30% and KOs around 60%. || Pink

| Ground Pink Shots || B> || Duon shoots pink lasers at the ground in the front. These lasers can be reflected or absorbed. Each laser projectile (around twelve shots in a row) deals up to 30% and KOs around 60%. This attack can be quite difficult to avoid on the higher difficulties. || Pink

| Charge || L or R || Duon charges forward quickly. Wheels do damage while tilted after dash (max 18%). Knockback can be either vertical or angled, depending on how Duon lands and on what part of his body hits the player. It is possible to be hit only by side by touching Duon's head, which deals less damage (max 20%) and decent knockback, KOing around 70%. It might be used several times in a row with little pause in between, especially when Duon has low [[health]]. || Both

| Spin || Unusable || Duon turns around, switching active sides and dealing damage. Used after Mines or Missiles. The hit inflicts up to 18% and has decent knockback, enough to KO at 70%. || Both

| Triple slash || Unusable || Duon slowly approaches, and then slashes three times when within range. He will turn around before slashing if the character jumps over him. Each hit deals up to 14%, except the third that deals the double (max 28%). The last inflicts decent vertical knockback. This attack can be fast and very difficult to avoid. || Blue

:''A robot with two upper bodies sharing one set of wheels. The blue-bodied half uses sword attacks, while the pink one uses lasers from his head and arms for offensive power. Whichever side is facing you will attack. Duon also threatens with homing missiles and the blade on top of the blue half.''

*Duon is the only [[boss]] that can hurt himself without the aid of [[items]] or a [[reflect]]or.

*It is possible to stand on Duon, between the two heads, although it only increases the chances to be KOed by any attack.  

*The word "DUON" is hidden on his wheels. This can be more closely seen when examined as a trophy or when using mods that remove the ingame camera limitations.
