Galvantula is a Stage 1 Lightning Pokémon with 80 HP. In the Pokédex this is Galvantula (#596), generation 5 (Unova). The card says it evolves from Joltik. In this catalog that name is Joltik (#595).

Galvantula (#596) has 16 other cards in the catalog. Those other cards are in 13 sets. The other printings with a release date run from 2011 to 2025. The earliest other card is Galvantula 46/114 in Black & White (2011). Both list 80 HP. The rarity there is Rare, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Hajime Kusajima illustrated this one. 12 other cards of Galvantula list a different HP.
The attack Discharge lists 30× damage. The cost is Lightning. Discard all Lightning Energy attached to this Pokémon. This attack does 30 damage times the number of Energy cards you discarded. Signal Beam is another attack lists 30 damage. The cost is Colorless, Colorless. Flip a coin. If heads, the Defending Pokémon is now Confused. Weakness is Fighting ×2. The flavor text reads "It creates barriers from electrified silk that stun foes. This works as a weapon as well as a defense."
I keep a set binder for Plasma Storm, meant to hold every card of that set. This card is one slot in the Plasma Storm set binder. A generation binder holds one card of each species. Galvantula can fill a slot in Generation 5 binder (Unova). I still need this card.
