Evil Rick looks almost identical to most other Ricks, despite changes with his shirt being black instead of light blue, his eyes had dark circles underneath, and his lips had a scar going across it.

He's known for his apathy towards Morty's, rather cruel tendencies and seems to have a connection to EviI Morty. It was discovered that hes an android, but he was destroyed.
However, the man that is standing in front of you, seems almost desperate. It doesn't even seem as if he's got a plan.
