Fusion Gwen was created by Fuse to assiant Fusion Ben in the space port; she also has another fusion location. Given her assignment, Fusion Gwen locates Ben Tennyson and studies the Omnitrix/Ultimatrix Progress Rate and at the right time, she steals a alien DNA sample when Ben transforms into a transformation. However, on her way to deverie the samples, Gwen drops the samples and the Hero's mission is to receive and return the samples before Fusion Gwen returns to retrive them. She then blocks the entrancce to Fusion Ben's Lab to convince the Hero that she had the last sample, the Swampfire Root. After the Hero defeats her, they then retrive the sample as it was formed into a Swampfire Nano.


  • Unlike Gwen, she seems to lack Mana making sense on how she traveled to Fusion Ben's Hideout instead of traveling there using Magic.
  • Unlike Gwen and Kevin, She doesn't seem to show any intrease or contact with Fusion Kevin, probably since Fusion Kevin is a Fusion of eleven year old Kevin instead of 16 or 17 year old Kevin.
  • This is the 15 year old Gwen, you can tell by the clothing.
