Duon

Duon
A boss in	Brawl
Universe	Super Smash Bros.

Duon (デュオン, Duon) is the sixth boss encountered in The Subspace Emissary. It doesn't hail from any particular series, and is unique to Super Smash Bros. Brawl.

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

Boss description

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 its 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). It rotates 180 degrees to change its attack strategy. The wheels it pivots on are the Yin and Yang symbols from Chinese belief, symbolizing balance and juxtaposition of two forces. 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.

Role in The Subspace Emissary

After Snake, Lucario, and Meta Knight kick all the Mr. Game & Watches out of the Halberd's control room, they fall to the bridge and dissolve into Shadow Bugs, which form into Duon, a last resort to defend the Halberd. It is confronted by Snake, Lucario, Fox, Zelda/Sheik, Peach, and 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 a trophy behind of Mr. Game & Watch.

Duon later reappears in The Great Maze and is refought by the playable characters.

Moveset

"Shared"

• Duon charges forward quickly. Wheels do damage while tilted after dash. Might be used several times in a row with little pause in between.
• Duon spins around. Vacuums (And pushes down if below edge, effectively negating many non-tether-based recoveries).
• 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 on higher difficulties.
• Duon turns around, switching active sides and dealing damage. Used after Mines or Missiles.

Pink Side active

• Duon shoots pink lasers with a vertical-spread coverage. Can be reflected or absorbed. It will aim higher and a little back if above or behind Duon.
• Duon shoots pink lasers at the ground in the front. These lasers can be reflected or absorbed.
• Duon's head glows, and then shoots three blue bolts that will pierce though everything (including the field and Duon, but it doesn't hurt himself) except Pit's Mirror Shield. At higher difficulties, it will break shields, so dodging is far preferable. Cannot be reflected or absorbed.
• Duon moves its non-weapon arm back to shoot four homing missiles. The missiles can be directed to hit itself. Can be detonated with vertical-ranged attacks or thrown items. Deals damage to Duon if the explosion hits it (Will also detonate on contact with Duon). Always followed by a "shared attack".

Blue Side active

• Duon slowly approaches, and then slashes three times when within range. He will turn around before slashing if the character jumps over him.
• Duon bashes its head forward.
• Duon readies its arms, then slashes making a large red shockwave. Very powerful.
• Duon launches several mines in the air. These can be detonated (won't hurt Duon) with vertical-based attacks, such as Pikachu's Thunder or a chucked item. Always followed by a "shared attack".

Like all bosses in Brawl, Duon gains an additional ×0.6 damage resistance modifier when fought in co-op mode, effectively gaining 67% more health. This modifier is applied whenever the second player is in-game, and is no longer applied if the second player loses all their stocks.

Trophy

Duon's trophy is obtained by using a Trophy Stand on it during the boss fight.

Duon

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.
