[@Holy Soldier]: Well, let's check this out, shall we?
First: Characters are not aware of the existence of a Multiverse unless it has been explicitly stated within their own canons, and even then they are limited to what exists already UNLESS they're being pulled from an alternate continuity where that already exists.
Next: Feels like something's missing for 'Overdrive' there. Needs more explanation.

And, uh... Well, I'm not seeing many more problems after those.
