Fusion is very hyperactive. He has many different interests. He likes to draw, flex, play video games (his favorite being Minecraft), and do origami, among other things. He has Autism and ADHD, both of which are highly functioning. This makes Fusion very random and unpredictable.
Fusion wears a pair of glasses so he can see, a digital watch, a survival bracelet and a green shirt with an Omnitrix logo on it, all of these excluding the glasses he found at the Garbage Dump. The shirt used to have sleeves, but they tore when Fusion flexed in front of a mirror. Fusion thinks his shirt looks better this way.
- An origami crane flies lazily around the bullet board. The crane flies into the Ink Sans's SKILL if Fusion has been hurt or if Ink is on the Genocide Route.
- An orange and a blue colored pencil spin across the bullet board, meaning Ink will have to either move or stand still. The blue pencil spins clockwise and the orange counterclockwise. This attack is faster on the Genocide Route.
- One way to spare Fusion is flexing at him three times. After the third flex, Fusion will flex too hard and flex himself out of the room, meaning Ink has won by default.
- Another way to spare Fusion is selecting the Origami ACT. Fusion, loving origami, will gladly make for Ink either an origami cup, flapping crane or a toxic crane. Doing this will unlock the yellow text. However, if Ink asks for an origami devil, Fusion will just laugh hysterically. If this happens, Ink will have to select Origami again.
