Octillery is a Stage 1 Water Pokémon with 80 HP. In the Pokédex this is Octillery (#224), generation 2 (Johto). The card says it evolves from Remoraid. In this catalog that name is Remoraid (#223).
Kouki Saitou illustrated this card. The same name is on 652 other cards in the catalog.
Octillery (#224) has 18 other cards in the catalog. Those other cards are in 17 sets. The other printings with a release date run from 2001 to 2026. The earliest other card is Octillery 34/64 in Neo Revelation (2001). Both list 80 HP. The rarity there is Uncommon, and here it is Rare Holo. Tomokazu Komiya illustrated that card, and Kouki Saitou illustrated this one. 13 other cards of Octillery list a different HP.
Suction Cups is listed as Poké-Body. As long as Octillery is your Active Pokémon, whenever the Defending Pokémon retreats, discard all Energy cards attached to the Defending Pokémon when it goes to the Bench. The attack Smokescreen lists 40 damage. The cost is Water, Colorless, Colorless. If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing. Weakness is Lightning ×2. Retreat cost is 2.
I keep a set binder for Aquapolis, meant to hold every card of that set. This card is one slot in the Aquapolis set binder. A generation binder holds one card of each species. Octillery can fill a slot in Generation 2 binder (Johto). I still need this card.
