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. He doesn't hail from any particular series, and is unique to Super Smash Bros. Brawl.

His name is derived from the Latin word duo, a word meaning twosome, or a group of two, alluding to his 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 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 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. He 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, he 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

Like all bosses Duon is controllable with hacks in Boss Battles Mode. The start button self-destructs any boss. Several of its moves gain OHKO power on the higher difficulties, usually Hard or above, and higher in Boss Battles.

Move	Input	Description	Side
Head Sword Chop	A	Duon bashes its head forward with high speed and immense knockback. It is an OHKO on Hard or higher difficulties (Very Hard in Boss Battles), while damage can reach 48%. Knockback can be both vertical and spiked, depending on how it lands; if the player stands on Duon, the hit always lands and has even more OHKO potential.	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, he will sustain enormous vertical knockback with OHKO power on Hard or above (Very Hard in Boss Battles). Damage can reach 62%. If the player stands on Duon during this move, he will be inflicted vertical knockback with guaranteed KO power just before the jump lands, no matter if he isn't hit. Being hit while midair also drastically increases the OHKO potential. Viceversa, if the player is only hit by the swords, he will be meteor smashed and take up to 20% damage.	Both
Vacuum Spin	Av	Duon spins around with a very strong Vacuum effect. On the higher difficulties (Very Hard or Intense in Boss Battles), multiple hits chaining can be an OHKO. It also pushes down the character if below edge, effectively negating many non-tether-based recoveries and dealing a meteor smash of OHKO power. Damage can surpass 100% if all hits chain on Intense.	Both
Sword Blast	A< or A>	Duon readies its arms, then slashes making a large shockwave. The hit itself deals immense knockback an can OHKO on Hard difficulty and above, or from Very Hard in Boss Battles. Damage is extremely high: a huge 85% on Intense; however, the slash itself has a low range. The shockwave inflicts high knockback (KOing under 40% on Intense) and up to 20% damage, also its hitbox is very large.	Blue
Mines	B	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". The mines are difficult to avoid, despite being slow, but they are also one of Duon’s weakest attacks, KOing at relatively high percentuals (over 100% on the lower difficulties and around 75% on Intense). Knockback is vertical, while damage is around 30% for each hit.	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 (although on higher difficulties it becomes progressively smaller). On lower difficulties in Boss Battles, all four missiles redirected to Duon can nearly KO the boss (or anyway reduce its health of at least 75%). The missiles can be detonated with vertical-ranged attacks or thrown items. They can damage Duon even if the explosion hits it (will also detonate on contact with Duon). Always followed by a "shared attack". These missiles are powerful, inflicting 30% at last and with enough power to KO under 50% on Intense difficulty. If all four missiles explode at the same time, it is an OHKO on Intense and deals 120% combined damage.	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 Pit's Mirror Shield. At higher difficulties, they will break shields, so dodging is far preferable, although difficult. Cannot be reflected or absorbed. Touching the blue sphere on Duon's head is an OHKO on Intense and deals up to 58%; also the beams are extremely powerful, being able to KO around 30% and inflicting high damages (up to 35%). The beam's High speed and the unpredictable beginning make this attack extremely dangerous.	Pink
Vertical Pink Shots	B<	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. Touching the pearl sphere on Duon's head is an OHKO on Intense, dealing a maximum of 58%. Each projectile (around 10 shots) 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. Although they are difficult to avoid, they are quite weak if compared to other Duon’s attacks (KOing over 70% and inflicting around 20% damage).	Pink
Charge	L or R	Duon charges forward quickly. Wheels do damage while tilted after dash (max 18%). On Very Hard difficulty it is an OHKO (Intense in Boss Battles), while damage can reach 45%. Knockback can be vertical or spiked, depending on how Duon lands and on what part hits. It is possible to be hit only by side touching Duon's head, which deals less damage (max 20%) and decent spiked knockback, KOing around 80%. 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 decent knockback, enough to KO at 80%.	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. All the slash chaining can result in an OHKO on Intense difficulty, only if the last hit lands. Each hit deals up to 14%, except the third that deals the double (max 28%), also the first two hits don't deal knockback, while the last inflicts high vertical knockback. This attack can be fast and very difficult to avoid.	Blue

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.

The Duon trophy in Brawl.

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.

Trivia

• Duon is the only boss that can hurt himself without the aid of items or a reflector.
• It is possible to stand on Duon, between the two heads, although it only increases the chances to be KOed by any attack. Also, standing during Jump Crash always ends in an OHKO.
• Sonic's Homing Attack will always home in on Duon's pink side.
• The word "DUON" is hidden on his wheels. This can be more closely seen when examined as a trophy.
• Duon shares a resemblance to bosses from other series represented in Smash.
  • The missiles that are fired out can be redirected to hit Duon, similar to Dr. Eggman's robot in The Doomsday Zone in Sonic the Hedgehog 3 & Knuckles.
  • Even though the color is different, the shockwaves that Duon fires out are similar to Dark Meta Knight's shockwave attacks in Kirby & The Amazing Mirror.
• Duon has 8 potential OHKO attacks, exactly as Galleom and Rayquaza and behind the only Tabuu, with a huge 14.
• If Duon is defeated while not attacking, it will use Vacuum Spin as his body becomes smaller before vanishing. Although the attack can KO the player and even OHKO on the higher difficulties, it will never truly KO since the battle is already won when the hitboxes land. However, in Boss Battles it can still inflict very high damage even after the player won.
