Krex is one of the four scientists of Primus. He looks to be maybe the smartest of the bunch, but for everything he's learned, he's probably forgotten twice as much. Krex has a terrible memory, and can often be heard trying, out loud, to sort all the thoughts he has whizzing around his great mind. Despite his muttering utterances, if he can work out what's on his mind, there might be no one brighter. He has black hair pulled back in a ponytail and wears glasses.
