Giovanni's Gyarados (Gym Challenge 5/132, First Edition Holofoil) is a Water-type Stage 1 Pokémon printed as a Rare Holo in the Gym Challenge expansion. It has two attacks: Summon Storm flips two coins to potentially deal 20 damage to each other Pokémon without applying Weakness or Resistance, and Dragon Tornado deals 40 damage and can force the opponent to switch a Benched Pokémon into the Active spot unless it Knocks Out the Defending Pokémon. The card carries a ×2 Grass weakness, −30 Resistance to Fighting, and a three-Colorless retreat cost which shapes its defensive and retreating choices.
