"JACK" is 16, lives with his single mother and is still trying to find himself and fit in. He spends most afternoons working the drive-thru window at the local burger joint in order to save up money to buy his first motorcycle...that is, until ARCEE becomes his guardian AUTOBOT Suddenly, JACK gets a killer bike AND big sister all rolled into one. Though he might be a little reluctant about it, JACK often ends up assuming the leadership role amongst the Teens and ends up being the voice of reason, practicality and safety...just as long as he doesn't need to impress a girl, in which case all of that stuff goes right out the window.
