Wigi's personality is mostly haphazard, though he has a certain level of organization. He can suffer extreme mood swings in a very short period of time and also have his rational thinking sky-rocketed/heavily downgraded. There are also times when he turns completely insane and drops on the floor, drooling until it goes away. Sometimes he just goes on a long-lasting state of catatonia. He also has a very intense problem with speaking and can barely communicate properly. This is all due to his genetic structure, which is heavily flawed.
