Onix
Wizards of the CoastSouthern Islands3/182001
$68.40Ungraded
PSA 10 $950
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
Wizards of the CoastGym Heroes21/1322000Rare
$9.97Ungraded
PSA 10 $238
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
Sun & MoonMcDonald's Collection 20199/122019
$9.29Ungraded
PSA 10 $58.32
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.

Onix
Scarlet & VioletPokémon TCG Classic - Venusaur10/342023
$8.99Ungraded
PSA 10 $50.99
Onix tunnels through a cross-section of earth here, its gray boulder body snaking diagonally across bands of pink, yellow and blue soil dotted with little Diglett faces peeking up. The art by Tomokazu Komiya has that crayon-textured, folk-art feel his fans love. As a reprint from the Venusaur deck of Pokémon TCG Classic, it draws collectors chasing complete Classic sets and Komiya's playful style.

Onix
Wizards of the CoastAquapolis98/1472003Common
$8.22Ungraded
PSA 10 $74.40
Onix rears up against a glowing orange sunset in this Aquapolis common, its rocky body lit from behind while a soft lens flare drifts across its coils and rolling hills fade into warm haze. Art by Hajime Kusajima gives it a painterly, almost cinematic feel. Collectors chasing the E-Card series appreciate these atmospheric commons, which are harder to find in clean condition than their rarity suggests.
- 6
Onix-GX
Sun & MoonHidden Fates36/682019Rare Holo GX
$2.96Ungraded
PSA 10 $82.99
Onix-GX swaps the usual drawn style for a rendered, almost cinematic look, with the rocky serpent lunging toward you, jaw wide open, inside a stadium with empty red seats behind it. Art by Planeta Igarashi gives the stone body real weight and texture. Hidden Fates is a heavily collected set, and this holo GX appeals to fans who like Onix and the realistic movie-style artwork.

Onix
EXFireRed & LeafGreen42/1122004Uncommon
$2.81Ungraded
Onix coils its boulder body around the frame here, jaws wide open in a roar as loose rocks tumble through a dusty canyon of jagged orange spires. Art by Kouki Saitou, the scene feels heavy and close, with the rocky segments filling nearly every corner. It's an Uncommon from FireRed & LeafGreen, a set fans of the Kanto remakes and the EX series chase for set completion.
- 8
Brock's Onix
Wizards of the CoastGym Heroes69/1322000Common
$1.47Ungraded
PSA 10 $199
Brock's Onix shows the rock snake rearing up with its jaws wide open, its boulder-chain body curling back across a hazy pink and violet backdrop in a soft painted style, art by Ken Sugimori. As a Common from Gym Heroes, it appeals to fans of Brock and his gym, and the trainer's portrait badge in the corner gives it that distinct Gym series charm collectors enjoy completing.

Onix
Wizards of the CoastNeo Genesis69/1112000Common
$1.32Ungraded
PSA 10 $70.00
Onix fills the frame here, coiled low inside a dark red cavern with its narrowed white eyes staring straight out at you and its horn rising against the jagged rock behind it. Art by Mitsuhiro Arita gives the scene a moody, painterly glow that feels more atmospheric than most commons. Collectors chasing a complete Neo Genesis set or fans of the original rock snake pick this one up for that brooding cave artwork.
