Brock's Onix Card Facts & History
5 facts about this card
Card History
Brock's Onix stands out as a rare, non-holo Stage Basic from Gym Heroes, giving one of Brock's signature partners a surprisingly premium slot in the set's early Trainer's Pokémon lineup.
In-Game
This card directly echoes Brock's role as Pewter City's first Gym Leader, whose Onix is the iconic roadblock many Kanto players remember from their very first badge battle.
Card History
Its Bind attack is a neat lore callback, because Brock's Onix is specifically noted as using Bind in both the original games and the anime.
Set Lore
Gym Heroes was the first English Pokémon TCG expansion built around named trainers and their partner Pokémon, which makes Brock's Onix feel like part of the moment the game started telling character-driven stories on cards.
Artist
Illustrated by Benimaru Itoh, the card captures Brock's ace in motion rather than a static pose, a style choice that helps it feel more like a scene from a Gym battle than a simple monster portrait.
