Collector’s notes

Onix 3/18 (Southern Islands)
Onix rises from a grassy island in this bright, storybook scene, with a Dragonite gliding overhead, Ho-Oh's golden wing sweeping in from the left, and a small Venonat peeking up from the rocks below. Art by Keiko Fukuyama, it is one of the Southern Islands cards whose backgrounds join into a larger panorama, so collectors chase it to complete that connected island picture.
Brock's Onix 21/132 (Gym Heroes)
Brock's Onix gets the early CG treatment from art by Benimaru Itoh: a blocky gray rock serpent bursting out of a rust-colored rock face against a starry black backdrop, wrapped in crackling green energy with boulders flying loose. The Gym Heroes owner-card concept, with Brock's portrait badge in the corner, gives it real charm, and the non-holo Rare appeals to fans of Brock and the Gym series alike.
Onix 9/12 (McDonald's Collection 2019)
Onix lies coiled low across the frame, its boulder-segmented body curling back into the distance while its craggy face stares out with a narrow, wary glare. The pink cracked-ice holo foil washes over the whole scene, giving the rocky snake a warm sheen. Art by Mitsuhiro Arita gives this McDonald's Collection 2019 promo extra pull for fans of his classic-era work and of the original rock serpent.
