# Onix #56/95 — Unleashed

## Summary

Onix is a bulk common from HeartGold & SoulSilver Unleashed, though it carries a small Pokémon quirk worth noting: the Energy Healer Poke-Body gave this Gen I rock snake some quiet staying power. MAHOU is a respected illustrator, and Brock's old guardian keeps a loyal fanbase among nostalgic collectors. A $0.79 modelled guide, up 36% over 30 days on 6 copies traded, says bulk, with 119 days of inventory on the board, and the economics stop there: PSA does not split this card’s population by finish, so no gem rate can be read for it, and the same card plays for $0.13 out of Mega Evolution.
