Mister Kaiser is a teacher at the International School, although it is not known what subject he teaches. His worst student is the Autobot Headmaster Junior Cab, who is a genius at playing pranks, but an idiot at everything else. Kaiser takes his royal student's failings personally, and has vowed to bond with his stupidest student, and thus inspire him to perform. Cab, in turn, has taken to avoiding Mr. Kaiser like the plague, and trained his pet parrot and armadillo to attack him on sight.
