Aquapolis is a set in the E-Card series. It was released on January 15, 2003. The printed size is 147. This checklist is longer, at 182 cards. Nidorino is 55/147, in position 55 of 182 on this checklist. Before it is 54 Marowak, and after it is 56 Pupitar. The listed rarity is Uncommon.
Nidorino is a Stage 1 Grass Pokémon with 70 HP. In the Pokédex this is Nidorino (#033), generation 1 (Kanto). The card says it evolves from Nidoran ♂. In this catalog that name is Nidoran♂ (#032). The card lists Nidoking, Nidoking (#034) under evolves to.
Kagemaru Himeno illustrated this card. The same name is on 656 other cards in the catalog.
Nidorino (#033) has 15 other cards in the catalog. Those other cards are in 15 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Nidorino 37/102 in Base (1999). That card lists 60 HP, and this one lists 70 HP. Both list the rarity Uncommon. Mitsuhiro Arita illustrated that card, and Kagemaru Himeno illustrated this one. 12 other cards of Nidorino list a different HP.
The attack Poison Horn lists 10 damage. The cost is Grass. Flip a coin. If heads, the Defending Pokémon is now Poisoned. Take Down is another attack lists 40 damage. The cost is Colorless, Colorless, Colorless. Nidorino does 10 damage to itself. Weakness is Psychic ×2. Retreat cost is 1.
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. Nidorino can fill a slot in Generation 1 binder (Kanto). I still need this card.
