Emerald is a set in the EX series. It was released on 1 May 2005. The printed size is 106. This checklist is longer, at 107 cards. Electrode is 27/106, in position 27 of 107 on this checklist. Before it is 26 Dodrio, and after it is 28 Grovyle. The listed rarity is Uncommon.
Electrode is a Stage 1 Lightning Pokémon with 70 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).
Masakazu Fukuda illustrated this card. The same name is on 471 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 70 HP. The rarity there is Rare, and here it is Uncommon. Keiji Kinebuchi illustrated that card, and Masakazu Fukuda illustrated this one. 36 other cards of Electrode list a different HP.
The attack Thundershock lists 20 damage. The cost is Lightning. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Speed Ball is another attack lists 50 damage. The cost is Colorless, Colorless, Colorless. Weakness is Fighting ×2. Retreat cost is 1.
I keep a set binder for Emerald, meant to hold every card of that set. This card is one slot in the Emerald 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.
