The villainous alter-ego of Professor Steven Boxleitner, a once-kind but easily distracted scientist. During an experiment intended to let humans read rodent thoughts, Boxleitner’s mind was accidentally merged with that of a malicious lab mouse named Squeaky. The fusion leaves him literally with “two brains” (one human, one mouse), turning him into a cheese-obsessed super-criminal and one of the chief antagonists of the WordGirl series.
