This quirk type is mostly transformer, but has a mutant quality about it, so let's just call it a type-hybrid quirk. I'm calling it "Tumirror" because it looks like a brain tumor in the body, but it's actually an organ that can copy nearby quirks. Plus, anyone with this quirk can't just activate it whenever they want. It only activates when the user's emotions are strong enough.

In shorter words:

Quirk: Tumirror

Quirk type: Type-Hybrid

Description: Looks like a brain tumor, but in actuality, when the user's emotions are strong enough, this organ allows the user to copy any nearby quirk.

Weaknesses: Only close enough quirks are up for copies (range varies by person), only works while emotions are that strong, can have some mental and physical damage on the body when used too often, can even cause temporary loss of memory or body function.
