Rhydon is Pokédex #112, generation 1 (Kanto). Brock's Rhydon is a Stage 1 Fighting Pokémon with 80 HP. The card lists level 38. The card says it evolves from Brock's Rhyhorn. In this catalog that name is Rhyhorn (#111). The card lists Rhyperior, Rhyperior (#464) under evolves to.
Brock's Rhydon sits at 2/132 in Gym Heroes, position 2 of 132. Before it is 1 Blaine's Moltres, and after it is 3 Erika's Clefable. The set belongs to the Gym series. It was released on August 14, 2000. The printed size is 132, and the checklist is the same length. The listed rarity is Rare Holo.
Bench Guard is listed as Pokémon Power. As long as Brock's Rhydon is Benched, whenever 1 of your Benched Pokémon is damaged, you may do 10 of that damage to Brock's Rhydon instead. (If more than 1 of your Benched Pokémon is damaged at the same time, you may use this power once for each of them.) The attack Lariat lists 70 damage. The cost is Fighting, Fighting, Colorless, Colorless. Flip a coin. If tails, this attack does nothing. Weakness is Grass ×2. Resistance is Lightning -30. Retreat cost is 3.
Rhydon (#112) has 19 other cards in the catalog. Those other cards are in 17 sets. The other printings with a release date run from 1999 to 2024. The earliest other card is Rhydon 45/64 in Jungle (1999). That card is named Rhydon, while this one is Brock's Rhydon. That card lists 100 HP, and this one lists 80 HP. The rarity there is Uncommon, and here it is Rare Holo. Kagemaru Himeno illustrated that card, and Ken Sugimori illustrated this one. 18 other cards of Rhydon list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Gym Heroes set binder is where a full Gym Heroes set goes. This card fills one slot there. A generation binder holds one card of each species. Rhydon can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto Gym Leaders and their Pokémon, and Brock and his Pokémon. I still need this card.
