Dark Blastoise (base5-20, First Edition) is a Water-type Stage 2 Pokémon from the Rocket set illustrated by Mitsuhiro Arita. Its Hydrocannon attack deals 30 plus up to 40 additional damage depending on extra attached Water Energy, and Rocket Tackle deals 40 while costing Dark Blastoise 10 damage and can grant damage prevention on a successful coin flip. The card has a ×2 Lightning weakness and a two-colorless retreat cost, positioning it as a heavy-hitting but somewhat vulnerable attacker in decks that can supply extra Water Energy.
