The HS—Unleashed expansion, released in 2010, includes Onix as card number 57 within the Pokémon Trading Card Game. Designed by Masakazu Fukuda, this Basic Fighting-type Pokémon features 90 Hit Points and a unique attack that relies on probability rather than fixed damage values. The "Swing Around" ability requires the player to flip two coins, dealing 20 damage plus an additional 20 damage for every heads result.

As a part of the HS—Unleashed series, this card represents a specific era of Pokémon TCG design and mechanics that appeals to nostalgic collectors and modern players alike. The card's gameplay mechanics encourage strategic decision-making, as the potential damage output depends entirely on the coin flips. This element of chance adds an exciting layer to matches, making it a memorable inclusion for any deck.
