Gyarados (#130) has 56 other cards in the catalog. Those other cards are in 38 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Gyarados 6/102 in Base (1999). That card is named Gyarados, while this one is Shining Gyarados. Both list 100 HP. The rarity there is Rare Holo, and here it is Rare Shining. Mitsuhiro Arita illustrated that card, and Ken Sugimori illustrated this one. 51 other cards of Gyarados list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Neo Revelation set binder is where a full Neo Revelation set goes. This card fills one slot there. A generation binder holds one card of each species. Gyarados can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Magikarp and Gyarados. I still need this card.
