Pretty much there's a couple canons at this point. But pretty much every canon except the reboot has their own take of what happens in the 90s. 2 they disband and a new team forms later on, 2 the originals keep on going and don't run out of jobs to do.One thing is certain: this officially retcons XGB as being an alternate universe...at least, I think so.
