Of course people say he’s a clone. Peter’s got enough of them to fill out an entire zip code. It’s almost a running gag that anytime someone in New York sees a spider-themed super they think the Jackal is responsible.
Oh wait you meant IRL. I keep forgetting you never play/read about the things you whinge about.
If you did you’d know he’s already had a several of his own comic lines with few to none appearances with Peter, been on a few teams, including being co-leaders of the Champions, was a central figure in at least 3 Event Comics, already has his own rogues gallery and, oh yeah, his Venom Blast are practically his WWE-esque signature finisher in almost every fight.
Like that last one is especially a self-report. His two biggest powers that separates him from vanilla Spiderman is his Venom Blast and his camouflage, but whereas the latter keeps getting forgotten about the former shows up almost every time he does.
