Also yeah, on the Universe cover, that's definitely Elias, he's got the weapons and the everything else. He tends to have brown hair in Universe in contrast to red hair in the main comic.
The two pink wolves are the twins from the Wolf Pack; that robot can't be Jules, makes no sense they'd change his looks, so it seems it's Metal Sonic. As to how is he alive, HE'S A ROBOT. They're rebuilt. Hell, Eggman's going through a Metal Sonic an issue, almost. Why wouldn't old Metal be rebuilt?
Ian's move forward to defend Larry's design means that's almost certainly him. Surprising to have Silver stay, to me at least. Not sure about the decision of using the Rivals suits, but eh.
On regards to the main book, there's actually something much more subtle that people didn't catch- how can Lupe be roboticized? She's covered by BEM immunity. And if Genesis altered the immunity, why aren't Sonic and Eggman roboticized?
