Activision announces Marvel Ultimate Alliance 2: Fusion

At its own event outside the walls of E3, Activision had a few announcements to make regarding its future lineup. One of the titles Activision focused on is the sequel to the poplar super-hero beat-em-up, Marvel Ultimate Alliance. In Marvel Ultimate Alliance 2: Fusion, players can -- for the lack of a better word -- fuse different superhero powers together and create their own crazy abilities. We really enjoyed the original Marvel Ultimate Alliance so we're happy to see a new title in the works. What powers would you create?

Clarification: By create your own abilities we mean by using multiple character abilities to create combos of attacks, not meshing them into a new ability to use.
