Staryu (#120) has 29 other cards in the catalog. Those other cards are in 28 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Staryu 65/102 in Base (1999). That card lists 40 HP, and this one lists 50 HP. Both list the rarity Common. Keiji Kinebuchi illustrated that card, and Hisao Nakamura illustrated this one. 19 other cards of Staryu list a different HP.
The illustrator line reads Hisao Nakamura. I count 71 other cards in the catalog with that illustrator.
Delta Species set binder is where a full Delta Species set goes. This card fills one slot there. A generation binder holds one card of each species. Staryu can fill a slot in Generation 1 binder (Kanto). I still need this card.
