Pokédex notes
Mega Aggron is a Mega Steel / Rock form in GO. Mega forms boost same-type allies in raids; lead with Mega when the lobby needs that type.
Where in GO: Mega Raids, Mega Energy, and high-tier events
Invest tip: Farm Mega Energy from Mega Aggron raids and events. Prefer Metal Sound or Iron Tail + Heavy Slam for Steel STAB while Mega (Meteor Beam loses Rock STAB). Keep a non-Shadow for Mega — Shadows cannot Mega Evolve.
