Barican

Barican (バリカン) (properly spelled Barrican by educated Ken fans) is Ken Izumi's robot companion. He is described as "grandpa robot" in the show as he talks with a stereotypical old man voice. His face resembles a duck and the pink balls hovering over his head will often show his mood. It's not known whether or not Barican was designed by Ken Izumi's father or where exactly he came from.

Barican accompanies Ken on many of his trips. He acts quite full of himself and jokes around a bit too much which leads to him getting captured or in trouble a lot. He is also the main source of the shows comic relief.

Barican can retract his head and limbs to form a sphere which can roll about. He can also propel himself while retracted to tackle enemies. Besides this feature, he doesn't appear to possess any other powers. However, Barican is able to establish some type of psychic link with Ken in episode 61.
