This Steelix is a Brock./ -type Pokémon owned by
Onix was given to Brock by his father, Flint, on his 10th birthday.
It first appeared as an Onix in Showdown in Pewter City, where Brock used it to battle Ash's Pikachu. Because it was part ground-type, it was unaffected by Pikachu's electric attacks. However, after it was dowsed with water, Pikachu was able to affect it with its electric attacks and ultimately knock it out.
Advanced Generation series
Some time in the future when Brock returned to Pewter City, he discovered that his Onix had evolved into Steelix.
