Tentacruel is Pokédex #073, generation 1 (Kanto). Tentacruel is a Stage 1 Water Pokémon with 90 HP. The card lists level 37. The card says it evolves from Tentacool. In this catalog that name is Tentacool (#072).
Tentacruel sits at 75/146 in Legends Awakened, position 75 of 146. Before it is 74 Tauros, and after it is 76 Unown [J]. The set belongs to the Diamond & Pearl series. It was released on August 1, 2008. The printed size is 146, and the checklist is the same length. The listed rarity is Uncommon.
The attack Tentacle Strike lists no damage number. Search your opponent's discard pile for up to 2 Energy cards and attach them to any of your opponent's Pokémon in any way you like. For each Energy card attached in this way, this attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Dangerous Poison is another attack lists 60 damage. The cost is Water, Colorless, Colorless. If Tentacruel has less Energy attached to it than the Defending Pokémon, the Defending Pokémon is now Paralyzed and Poisoned. Weakness is Lightning +20. Retreat cost is 1. The flavor text reads "With 80 tentacles for ensnaring victims, it prevents escape until the prey is weakened by poison."
Tentacruel (#073) has 15 other cards in the catalog. Those other cards are in 14 sets. The other printings with a release date run from 1999 to 2023. The earliest other card is Tentacruel 44/62 in Fossil (1999). That card lists 60 HP, and this one lists 90 HP. Both list the rarity Uncommon. Kagemaru Himeno illustrated that card, and Kouki Saitou illustrated this one. 14 other cards of Tentacruel list a different HP.
The illustrator line reads Kouki Saitou. I count 652 other cards in the catalog with that illustrator.
Legends Awakened set binder is where a full Legends Awakened set goes. This card fills one slot there. A generation binder holds one card of each species. Tentacruel can fill a slot in Generation 1 binder (Kanto). I still need this card.
