Replicants as an Antagonist

[BaneOfGiygas]

What happens when you emag a replicant

The replication procedures start going batshit insane, resulting in your powers getting completely swapped after use, the precise frequency of which I have yet to think of. This would tag the replicant as a not-human immediately, but the power-swapping would start resulting in normally contradictory sets, having more powers than should be feasible, or even gaining access to abilities that are otherwise totally unreachable. Emagging a replicant would be a risky gamble, but might result in a frighteningly powerful entity that can do lots of harm on its own.

Alternatively, it makes them talk like Arnold Schwarzenegger. That works too.
