Mad Harangue appeared identical to the prime version's human form, but he dressed in more rugged, makeshift, desert-raider clothing which made him loosely resemble Jack Sparrow.
Mad Harangue was fanatically loyal to Mad Ben, praising him as their leader and smearing Mad Ben's enemies, and he would quickly grovel in fear at Mad Ben's feet.
He was a mid-ranking member among Mad Ben's mining slaves until he was regressed to an infant by a time ray from Maltruant that was intended for Dr. Psychobos. Harangue's new infant state may be permanent since Maltruant mentioned its effect would bestow "eternal youth" (though that may just have been a lie Maltruant told Psychobos).
