>>I'm not so sure cats don't count as super-powered already.<<

Well, they have a healing purr, and survive trauma so well they're said to have 9 lives. It's not far from there to superpowers. Oh, and we had a cat who could walk through walls -- named Pixel for that precise ability.

>> You do know Chernobyl has a feral cat colony living in the remains of the reactor core... because it stays nice and warm during winter... and apparently they suffer no ill-effects from continuous exposure to radiation levels that would kill a human within minutes. <<

I had not heard of the cats, though I have heard of other wildlife there. Power Absorption kitties, yikes.

>> Hmm... there's an idea, 'and the cat came back' i.e a breed of immortal, indestructible cats. <<

It could work.

>> Now all they'd need is opposable thumbs and a higher IQ and both traits already exist among other cat populations. Of course, being cats, I'd doubt world domination would actually be an objective for them. Too much effort! <<

There are polydactyl cats who have opposable digits.

>> Oh well, just so long as it's not super-powered cockroaches... [Marvel did that one, it was gross.] <<

I have sentient cockroaches, although not super ones, over in Submerged Nebraska. So I probably won't do those in Polychrome Heroics.
