As Mad Mechanic, Kenneth is intended as entirely black and purple in appearance, intending to rescue the day in a favorable way. Kenneth has spiky black hair, wearing black suspenders, PRPL button shirt including black overalls with a grey white t-shirt under it and with black leather gloves on each of his hands. He resembles the stereotypical mad scientist, bearing a wide-open smile, with glasses instead of goggles. 

Furthermore, Kenneth has a 100% chance of saying Mechanic's rare voicelines.
