At school, Will also has an enemy named Warren Peace.  The Commander put Warren's father away for three life terms.  During a lunch, Warren gets very mad at Will and starts throwing fireballs, which is his superpower.  Will dives under a bench.  It is here his power comes to him; super strength, like his dad.  He manages to defeat Warren and both are put in a time out room where their powers do not work.  His mother is not happy, but his dad is very happy that Will has powers.
