His brother :3c

Also related to that he owns a collection of highly specific mechanical bits and pieces and he gets super excited anytime he can use any of them.

And unrelated but both him and Blixer have issues with their vision amongst other things. (In my Jsab au they’re both “powerless” shapes which is an illness which as the name suggest means they have no power of their own ((I mean, as far as I remember neither use their powers before getting corrupted)) but it also has other symptoms such as problems with vision and motor skills, and their eye shape is also a side effect :3)
