XY is a set in the XY series. It was released on 5 February 2014. The printed size is 146, and the checklist is the same length. Electrode is 45/146, in position 45 of 146 on this checklist. Before it is 44 Voltorb, and after it is 46 Emolga-EX. The listed rarity is Uncommon.
Electrode is a Stage 1 Lightning Pokémon with 90 HP. In the Pokédex this is Electrode (#101), generation 1 (Kanto). The card says it evolves from Voltorb. In this catalog that name is Voltorb (#100).
Shigenori Negishi illustrated this card. The same name is on 151 other cards in the catalog.
Electrode (#101) has 45 other cards in the catalog. Those other cards are in 39 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Electrode 21/102 in Base (1999). That card lists 80 HP, and this one lists 90 HP. The rarity there is Rare, and here it is Uncommon. Keiji Kinebuchi illustrated that card, and Shigenori Negishi illustrated this one. 27 other cards of Electrode list a different HP.
The attack Eerie Impulse lists no damage number. The cost is Lightning. Flip a coin. If heads, discard an Energy attached to 1 of your opponent's Pokémon. Rollout is another attack lists 40 damage. The cost is Colorless, Colorless. Weakness is Fighting ×2. Retreat cost is 1. The flavor text reads "It explodes in response to even minor stimuli. It is feared, with the nickname of "The Bomb Ball.""
I keep a set binder for XY, meant to hold every card of that set. This card is one slot in the XY set binder. A generation binder holds one card of each species. Electrode can fill a slot in Generation 1 binder (Kanto). I still need this card.
