Trini's famous scientist uncle Howard drops by the Youth Center, with a new invisibility formula. Rita spots it, and plans to use it on her new monster, the camouflaged creature known as the Dark Warrior. Billy gets sick of Bulk & Skull picking on him, and decides to reenroll in Jason's karate class. But as before, he doesn't fare well in it. Uncle Howard, not only a scientist but a master martial artist, offers to give him some training at the park. There, Dark Warrior kidnaps him, and orders him to give up the invisibility formula.
