Mewtwo (Mega X) in Emerald Imperium

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

Compared with the official games

Against the base species it is built from:

Stats Attack 110 → 190, Defense 90 → 100, Sp. Def 90 → 100 (total 680 → 780)
Type Psychic → Psychic / Fighting
Abilities gains Steadfast and loses Pressure, Unnerve

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.
