Coop's builds the world's most powerful universal remote - and Skalgar (who Coop and Jamie called "School Girl"), an ignorant, alien criminal with an inferiority complex, wants it, believing its (non-existent) destructive power can boost his reputation. Coop underestimates his short opponent, and Skalgar teleports the remote to his own mech. Coop then typically destroys half of Jersey City attempting to recover the remote.
