Dark Blastoise (base5-20 Unlimited) is a Stage 2 Water Pokémon from the Team Rocket expansion. Its Hydrocannon attack does 30 plus up to 40 additional damage based on extra Water Energy attached, and Rocket Tackle deals 40 but deals 10 self-damage with a coin flip to prevent damage next turn. The card has a ×2 Lightning weakness and a two Colorless retreat cost, making it a high‑damage but somewhat risky attacker in decks that can support heavy Water Energy attachment.
