As a fan of the "Great Scott" stories I'm delighted to see this.
The idea of a character breaking the fourth wall knowing she's a comic book character owing to her experience with parallel universes and regarding it as equivalent to starring in a reality show is an idea that will have other creators kicking themselves for not having thought of it first.
My only quibble is that Fusion's narration tends to be overly wordy. I totally understand the temptation but you have to be especially harsh with yourself. I always favored the rule (alternately credited to Stan Lee or Mort Weisinger) than a standard comics panel can only usefully hold 30-35 words. That's counting all word balloons, thought balloons, narration, and footnotes. (N.B.: that's based on a five or six panel page, so really what you're aiming for is to avoid going much over 200 words on a page.) Obviously the rule CAN be broken with impunity, but it's one of those "you need to know the rule and practice it before you should break it" deals.
Other than that, I'm liking it and definitely interested in seeing more.
