Onix in Emerald Imperium

Rock / Ground — where to catch it, what it learns, and how it differs from the official games.

Compared with the official games

Stats HP 35 → 50, Attack 45 → 60, Defense 160 → 150, Speed 70 → 65 (total 385 → 400)

Compared against present-day official data. The Fairy type and hidden abilities arrived after Pokémon Emerald, so a difference here can belong to the series rather than to this hack.
