As if fighting He Who Must Not Be Named isn't enough, in Harry Potter's fourth year at Hogwarts, he is thrust into the dangerous Triwizard Tournament, where he must obtain an egg guarded by a ferocious Hungarian Horntail. Harry doesn't exactly tame this dragon, but he does manage to narrowly escape being eaten thanks to a spell that summons his broom. Plus, in their seventh year, Harry, Ron, and Hermione, escape Gringott's Bank by climbing onto the back of the dragon guarding a vault, and manage to survive this endeavor.
