Bokkun
From Sonic Retro
Bokkun the Messenger Robo is a character in the show Sonic X. He is a small, black, gold-eyed robot with blue and white patches, and has the ability to fly. He carries a pale green rucksack over his shoulder, in which he keeps a television used to relay messages from Dr. Eggman to Sonic.
He was created by Dr. Eggman to act as a go-between, and is apparently designed to be very annoying but non-threatening. He is programmed to start crying loudly for no particular reason, and likes to detonate small bombs which leave the victim covered in soot. Bokkun is also very loyal to Eggman, and has an extremely bad temper.
