It's one of the most clicheed and bog-standard "power" choice that crops up freaking everywhere. My problem is not with copying per se, but with its implementation.
For example, my power COULD be seen as a standard "adaptation" power, however instead of going the "evolving body that somehow counters every power after the first hit" I specified that it works to overcome specific PROBLEMS(and not weapons or damage types, mind you), that it would not be able to do so on the run, etc.
In short - if you're taking high-power option, please at least do so tastefully and with style, as opposed to being one of those Rogue-clones or whoever.
