@TheUnknowable: Hm...
Okay, first and foremost, honest opinion: barring Inuyasha, the forms are all very, VERY light on information and detail. The personalities are also barebones for all three of them; the longest one's barely 3 sentences, dangit.
Now for more specifics. I like detail: what a character can do, what their limits are, etc;. Giving me a flat list of stuff without elaboration is like tossing a bunch of words in my face that have no meaning whatsoever.
How strong?
How fast? What defines "superhuman"? Because we're ALL over the spectrum here.
To hit on the next set of forms in turn:
Inuyasha: mostly fine. Needs (A LOT) more fleshing out overall, but fine.
Spock: Issue. Prime Directive. That is all.
Well, not really. He's kinda on the bland side, and idk what he's really DOING in this relatively crazy-powered cast (he doesn't particularly stand out much AT ALL even among the more normal guys) but big issue is Prime Directive rn.
Nightcrawler: I do not... Like characters who can TP on a whim without limitations. In a way, this loops back to lack of detail, but even so. Big issue.
That's... About it from me for now, I think.
