Greater Mimic

Greater mimics are mimics that have been upgraded by Weavers. According to TranStar research, they have the ability to turn into more complex objects like EATs and Operators, but has yet to be observed doing so. Greater mimics are more resistant to trauma than are normal mimics, and they are the only mimics that are capable of killing player characters by jumping onto their faces and leeching them.

Strategy
Greater Mimics have to be immobilized before killing, as they (unlike regular Mimics) can jump on Morgan's face, making player helpless against other enemies in the area until they get them off.
