From the Spider-Verse panel at C2E2, here are some of the confirmed Spider-Men appearing in Spider-Verse.
Spider-Man from the cartoons.
Peter Porker, Spider-Ham
Electric Company Spider-Man
Miles Morales, Ultimate Spider-Man
A new British Spider-Man who Dan Slott says UK folk will be cosplaying as for years (Judge Spider?), as well as 1602’s Peter Parqhar.
Japanese TV Spiderman
Spider-Woman and Arana
Ben Reilly Spider-Man
An assassin Spider-Man whose webshooters shoot bullets from What If: Spider-Man Vs Wolverine by Jeff Parker, Paul Tobin and Clayton Henry.
But there will be no Sony cinematic Spider-Man versions.
And Spider-Boy from Amalgam is legally iffy.
