What Is On This Card?

Evolves from: Nidorino

Poké-Body

Crystal Type

Whenever you attach a Grass, Lightning, or Fire basic Energy card from your hand to Nidoking, Nidoking's type (color) becomes the same as that Energy card type until the end of the turn.

Attack · 20 damage

Poison Horn

Grass + Grass + Colorless energy. The Defending Pokémon is now Poisoned.

Attack · 50 damage

Rolling Thunder

Lightning + Lightning + Fighting + Fighting energy. Flip a coin, If heads, this attack does 10 damage to each of your opponent's Benched Pokémon. If tails, this attack does 10 damage to each of your Benched Pokémon. (Don't apply Weakness or Resistance for Benched Pokémon.)

How To Research This Printing

Start with the image, Aquapolis set name, and 150 / 147 collector number. Those identifiers matter more than the character name alone because the Pokémon TCG can reuse names across reprints, promos, alternate artwork, and later expansions.

Next, match the finish and condition. A holofoil, reverse holofoil, unlimited, or first-edition listing may carry a different reference price even when it belongs to the same card printing. Grading adds another layer: raw marketplace references should not be treated as prices for PSA, Beckett, or CGC slabs.

Finally, compare the visible update date with current marketplace listings and recent sold results. MonZap gives you a fast catalog reference, set context, and scanner workflow, while the linked marketplaces help you check what is available right now.
