@mantequilla: When their Egon was zapped by the spook after the grimoire, the team used the dimensional doorway (which they built in the TMNT crossover) to recruit the Egon from the RGB's world (as depicted in "Ghostbusters Get Real").
In that book on footprints, they forgot ROM, Godzilla, Man-Thing, Devil Dinosaur, HERBIE, the Lizard, M-11, and Hulk.Also, based on the look of that fist construct, looks like Guy got literally boned by Sinestro.
@warlockmage: He looks like someone who'd grace the cover of a 70's soft-rock album. (A Gordon Lightfoot one, maybe?)
Nice take on Rush--don't often see band-themed commissions, and lately when you do, it's mostly the Beatles.
