(Okay. I think I've got this now.) Shiandu and Shiudo are insane twins. According to previous personality changes, they are more like androids (Bleh. I was bored. And I like robots.) but of course not created by Dr. Gero. They have nothing to do with the numbered androids. They still fight and they still invent things, but they are on sort of a lower profile for a while. They aren't freaks. They aren't losers. They're just twins. Twins that (in written stories) have created hover crafts, more siblings (Robots!) and TOAST! Everyone likes toast. They still like Dragon Ball. Everyone likes Dragon Ball.
