Mi (ミーくん Mī-kun) - A cyborg cat created by Dr. Go to exterminate Kuro. He appears as a frequent "goon" of his but is in fact kind-hearted and noble. At a later part of the story where Go accepts defeat and turns down on his conquest to world domination, he is now often seen helping him and in times helping Kuro too. They are seen training together which often leads to them fighting for real which is to be stopped by Nana. Opposite to Kuro, Mi prefers a sword as his standard weapon. He can add himself to any weapon and additional items to them.
