Pokémon Season 5 Episode 43

Fangs for Nothin'

No sooner has Ash begun what he hopes will be his final gym battle in the Johto League than Team Rocket once again throws a wrench into his plans, making off with the Dragon Fang, an invaluable heirloom long held by the Blackthorn Gym. Ash and friends, along with the gym leader, give chase, but in their flight, Team Rocket leads them deep into a secretive area rarely visited by anyone but the Dragon Pokémon that dwell there. Perhaps angered by these uninvited guests, a large beast flies directly at Ash and friends as soon as they enter this area. Uncertain whether this shape be friend or foe, our heroes raise their guard and wait as it grows closer… and looms larger still.
