As long as it has two arms and two legs and some sort of futuristic unbreakable alloy for a skeleton on which is hung a genetically engineered, nanotech-enhanced musculature, with high-performance organs that can't be damaged through use and all wrapped in a bulletproof, fireproof, cutproof, electricityproof, etc. etc. and as long as EVERY NEURON IN THEIR HEAD!!! is upgraded so they find classes so easy at the academy, I'll be happy.
