Justin has trouble trying out for sports, as he's too small and young to compete with the other teens. When an ant, mutated by Bulk & Skull's strange exterminator spray, bites him, he discovers he now has super strength! This makes him a hit with athletics, but the side effect is he's unable to morph. He's forced to choose between a life as a Ranger or a life as a dumb jock. Meanwhile, Divatox prepares to bring to Earth the first of her three Evil Zords, the first being her very own bird-like Divazord.
