Brock's Onix is card number 21 in the Gym Heroes set, released by Pokémon in 2000. As a Fighting-type Pokémon, this Basic card carries 70 Hit Points and is designed to support players looking to control the board state during gameplay. The card was illustrated by Benimaru Itoh, whose artwork brings the Rock-type Pokémon to life within the context of the early 2000s TCG era. The card features two distinct attacks that define its strategic utility. The first, Bind, requires the player to flip a coin; if the result is heads, the Defending Pokémon becomes Paralyzed, potentially hindering its next turn. The second attack, Tunneling, is particularly potent against opponents with multiple Pokémon on the bench. It allows the player to choose up to two Benched Pokémon and deal 20 damage to each, ignoring Weakness and Resistance for those targets. Collectors often seek out Gym Heroes cards for their nostalgic value and the deep lore they introduce regarding the Kanto region's gym leaders. Brock's Onix represents a key piece of that narrative, showcasing the strength and resilience of the protagonist's first major ally. For investors and hobbyists alike, this card serves as a tangible link to the foundational years of the Trading Card Game, offering a glimpse into the design philosophies and mechanics that shaped the hobby. Whether you are building a complete set of Gym Heroes or focusing on specific Pokémon types, Brock's Onix offers a unique blend of mechanical depth and historical significance. Its ability to disrupt opponent strategies through paralysis and multi-target damage makes it a standout card for enthusiasts who appreciate the complexity of early TCG design.
