Mute but can answer yes/no questions with 8-ball in chest
Baron Ünderbheit (Former master)
Manic 8-Ball is a human with the powers of a magic 8-ball. Lacking a mouth, he never speaks, instead using the 8-ball messages on his chest to answer yes or no questions (except for one message, in which he calls Ünderbheit an "asshole").
He, along with Catclops and Girl Hitler, were accused by Baron Ünderbheit for treason and "executed" by tiger-bombs. Despite surviving the combination of tiger attack and explosion, he was captured and remained a prisoner of Ünderbheit, who used his eight-ball power for advice.
