Fusion Ben is a copy made of fusion matter, a monster created by Fuse, from the game FusionFall.
Fusion Ben resembles Ben Tennyson but Fusion Ben has green hair, a dark green tank, red jacket with a black stripe, dark green jeans, red eyes, an Omnitrix/Ultimatrix (not functional) and Fusion Matter skin.
HistoryEditFusion Ben was created by Fuse and was in charge to cover the Space Center with Fusion Goo. Fusion Ben then held Fusion Gwen responsible for bringing him DNA samples from his doppelgänger, Ben Tennyson, so he can create Fusion Monsters for Fuse as an additional mission. The Hero is called to retrieve the samples that Fusion Gwen had dropped and to bring them to Ben one at a time. Finally Ben gives you a mission to enter the space port and defeat Fusion Gwen in order to receive the last sample, a Swampfire root. It turns out Fusion Ben used Fusion Gwen in order to buy some time to create to Fusion but the Hero destroys Fusion Gwen just in time to stop Fusion Ben from making any Fusion Monsters.

- Fusion Ben is similar to Ben because he doesn't think things through like when he took the princes device but didn't expect to be shot at and how he didn't expect the hero to come to finish Fusion Ben off AKA destroy him.
