Korn, Slipknot, RA (Easiest UU!)
Or have some fun...
Papa Roach - UU, A GIANT ROACH!
But for my suggestions, Korn, Slipknot and RA
With RA...
UU - RA
Units - Egyptian Flavor Units (to go along w/then name)
Spiknot...
UU - ??
Mby the goat from the Iowa cover? Could be an early unit, require no support, and like be fast?
Korn...
UU - ??
Not sure at all. How about a security guard from Freak on a Leash? He would be a cheap fot infantry that moved fast but had low attack; something like that.
Those are my thoughts!
