But it has to be the Original Series original 10, as we now have the remake of it that tossed all the aliens into a hat and drew random ones out.

The only other one I would let slip through would be Cannonbolt, as he was supposed to be one of the original 10, but was edged out by Diamondhead. Because of this, Cannonbolt would only be accessibly by accident.

As for Omniverse, I stopped watching after Ultimate Alien and the art style of Omniverse didn't do much to sell me.

In short: Prototype/Original Series + Cannonbolt
