So basically it's a free for all with each universe's members fighting together. That's tough. Basically it's: Halo: Halo Array, Flood, Forunners, Precoursers Mass Effect: Reapers, Crucible Destiny: Darkness, Traveller, Vex Doctor Who: Daleks, Timelords, bunch of weird shit Transformers: I'm not going to pretend to know these names. Star Trek: Red Matter, Doomsday Device DC: I can't even Marvel: Dem Aliens, Hulk, More weird shit War hammer: I don't even know Dead space: do they even have anything? Star Wars: Galaxy gun/Death Star, star forge/engine, crazy sith.
