Stormfront is a set in the Diamond & Pearl series. It was released on November 1, 2008. The printed size is 100. This checklist is longer, at 106 cards. Steelix is 28/100, in position 28 of 106 on this checklist. Before it is 27 Staraptor, and after it is 29 Tangrowth. The listed rarity is Rare.
Steelix is a Stage 1 Metal Pokémon with 130 HP. The card lists level 63. In the Pokédex this is Steelix (#208), generation 2 (Johto). The card says it evolves from Onix. In this catalog that name is Onix (#095).
Naoyo Kimura illustrated this card. The same name is on 256 other cards in the catalog.
Steelix (#208) has 33 other cards in the catalog. Those other cards are in 23 sets. The other printings with a release date run from 2000 to 2025. The earliest other card is Steelix 15/111 in Neo Genesis (2000). That card lists 110 HP, and this one lists 130 HP. The rarity there is Rare Holo, and here it is Rare. Ken Sugimori illustrated that card, and Naoyo Kimura illustrated this one. 33 other cards of Steelix list a different HP.
The attack Outbreak Power lists no damage number. The cost is Colorless. Choose a number of your opponent's Pokémon up to the amount of Energy attached to Steelix. This attack does 20 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.) Iron Tail is another attack lists 100× damage. The cost is Metal, Metal, Colorless, Colorless. Flip a coin until you get tails. This attack does 100 damage times the number of heads. Weakness is Fire +30. Resistance is Psychic -20. Retreat cost is 4. The flavor text reads "Tempered underground under high pressure and heat, its body is harder than any metal."
I keep a set binder for Stormfront, meant to hold every card of that set. This card is one slot in the Stormfront set binder. A generation binder holds one card of each species. Steelix can fill a slot in Generation 2 binder (Johto). I still need this card.
