Help! I'm needing a comprehensive list of Mutants from all iterations

[neatoman]

OK, let's see what I can contribute:

Canonically, the only other mutant to be created through the Utrom Ooze in Mirage is Leatherhead, as far as I know. Beyond that though, the failed clones of Shredder might count. Members of the Justice Force may have been Mutants in the X-Men sense of the word but their origins are hardly ever mentioned.

I know you excluded 4Kids show, which I assume is because it rarely featured other humanoid animal mutants, the only other one is Leatherhead and aside from that we have Hun along with the guys Shredder mutated in Turtles Forever. But the underground mutants may or may not have been mutated through Utrom Ooze or something similar. J. Finn, the guy Bishop experimented on, would qualify as a mutant. I'm pretty sure Bishop himself is a mutant of sorts, even if his human appearance isn't compromised. Baxter's transformation in Fast Forward might count. We also have the mutants created by the staged alien invasion. Then of course there are clones and AU versions of the Turtles, though that might not count because of how cheap that would be.

For Fred Wolf, not sure honestly. There are a bunch of really weird ones, like a hamster that completely turned human and a bunch of microbes that fused together with ice to form a giant humanoid, so it's kind of insane to try and list them all.

With Archie it's a little easier, discounting what was directly inherited from Fred Wolf: Ray, Manmoth, Mondo, Wyrm, that Chameleon guy, the Conservation Corps, The Uncanny Trio, Manx and Bob. Dreadmon is supernatural, so not really a mutant. Slash is excluded because he's seemingly not a mutant, just some weird alien that looks like the Turtles by coincidence.

IDW... Look, let's just ignore Mutant Town because A, most are background fodder and B, most of them are likely going to return to human form at some point. Let's also ignore time travel and alternate universes. With that in mind you have Hob, Alopex, his Mutanimals, Dreadmon, Slash (his clones), Zodi, the Fly-Borgs, Krisa, Leatherhead, Wyrm, Anchovy and the Gang of Four (who are evidence that mutations can be reversed through cybernetic pumps and the reason I doubt most mutants will remain mutants). All things considered, IDW was fairly restrained with this until Mutant Town. Beyond that, you Bishop who appears to be a natural Mutant and Ravenwood who is a failed experiment.

2012 and Rise have a similar problem to Fred Wolf in the sense that they just keep doing weird nonsense with the Mutagen.
