🧬 About Mega Aggron in Pokémon GO

Mega Aggron is a Steel-type Pokémon. When Mega Evolved, it loses its Rock typing and becomes a pure Steel-type Pokémon, which gives it huge defense but also clear weaknesses.

Mega Aggron is useful because:

• It boosts Steel-type attackers
• It is extremely tanky and survives a long time in battles
• It is useful in some niche PvP and raid situations

Weaknesses & resistances

Notes When Aggron Mega Evolves, it becomes pure Steel-type, which removes many of its old weaknesses but leaves it very vulnerable to Fighting, Ground, and Fire-type attacks. Among these, Fighting- and Ground-type Pokémon like Lucario, Machamp, Conkeldurr, Garchomp, and Groudon usually perform the best.
