Huh. Okay, I never heard of Ballblazer, and I interpreted "rotofoil" as just a fancy way of saying "helicopter", especially with the sprouting blades and whatnot.
If that's the case, and I had to quantify it in GURPS, then I'd call it a wereform with a bunch of switchable advantages. I'd have to sit down with the books and a proper description to work up specifics, but that's probably more than anyone cares to see. Especially me.
