Editing Duon

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

'''Duon''' ({{ja|デュオン|Duon}}, ''Duon'') is the sixth [[boss]] encountered in [[The Subspace Emissary]]. It does not hail from any particular series and is unique to ''[[Super Smash Bros. Brawl]]''. Duon was created from several [[Shadow Bug]]s that had gathered into a single powerful entity.

Duon is a two-sided robotic entity on a set of wheels; one of its sides is pink and has a cannon atop its head and a pair of arm cannons and the other is blue with a pair of twin blades and a larger and curved blade on its head. Both sides have shoulder exhaust pipes which missiles (associated with its pink side) or mines (associated with its blue side) can be fired from. Duon rotates one hundred eighty degrees to change its attack strategy. The faces of its wheels bear a representation of [[wikipedia:Yin and yang|the yin and yang symbol]]. There is an invisible platform between Duon's halves, making it one of only two bosses that a [[fighter]] can actually stand on, the other being [[Porky Minch]].

When {{SSBB|Snake}}, {{SSBB|Lucario}} and {{SSBB|Meta Knight}} attempt to dispose of all the [[False character|false]] {{SSBB|Mr. Game & Watch}}es in the Halberd's control room, they fall onto 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}}, while Meta Knight stays behind to retake his ship. The boss battle makes up the entirety of the [[Battleship Halberd Bridge]] level. After Duon is vanquished, it dissolves into Shadow Bugs and flies away, leaving behind the trophy of the real Mr. Game & Watch, which Peach revives.

|  || {{Button|GCN|A|s=32px}} || 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

| Slash ({{ja|斬りつけ|Kiritsuke}}) || {{Button|GCN|A|s=32px}}+{{Button|GCN|D-Pad|L|s=32px}}/{{Button|GCN|D-Pad|R|s=32px}} || Duon readies its arms shaping a cross, then performs a sweeping attack that makes a large shockwave in front of it. 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

| Bomb Drop ({{ja|爆弾投下|Bakudan Tōka}}) || {{Button|GCN|B|s=32px}} || Duon launches several mines in the air. These can be detonated (but will not harm 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 Missile ({{ja|誘導ミサイル|Yūdō Misairu}}) || {{Button|GCN|B|s=32px}}+{{Button|GCN|D-Pad|U|s=32px}} || 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

| Triple Beam ({{ja|三連ビーム|Sanren Bīmu}}) || {{Button|GCN|B|s=32px}}+{{Button|GCN|D-Pad|D|s=32px}} || Duon's head glows and then shoots three strong blue bolts that will pierce though everything (including the field and Duon, but they do not hurt itself) except {{SSBB|Pit}}'s [[Mirror Shield]]. At higher difficulties they will break shields. 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

| Rapid Fire ({{ja|連射|Rensha}}) || {{Button|GCN|B|s=32px}}+{{Button|GCN|D-Pad|L|s=32px}} || 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

| Rapid Fire ({{ja|連射|Rensha}}) || {{Button|GCN|B|s=32px}}+{{Button|GCN|D-Pad|R|s=32px}} || 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

|  || {{Button|GCN|L|s=32px}}/{{Button|GCN|R|s=32px}} || 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 its 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

| Triple Attack ({{ja|３連攻撃|Sanren Kōgeki}}) || Unusable || Duon slowly approaches and then slashes three times when within range. It will turn around before slashing if the character jumps over it. 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

Duon's Spirit Battle uses a [[giant]] {{SSBU|Ice Climbers}} puppet fighter starting off with a [[Super Scope]], referencing Duon's dual sides and the pink side's built-in laser blasters, and is fought on the [[Halberd]] stage's ship deck layout. During the battle, Shooting Type items will appear, further referencing the shooting attacks.

*Duon is the only [[boss]] that can hurt itself without the aid of [[items]] or a [[Reflection|reflector]].

*{{SSBB|Sonic}}'s [[Homing Attack]] will always home in on Duon's pink side.

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