Mega in GO: Activated with Mega Energy and temporary (8 hours). While active, every trainer in the raid gets an attack boost — larger for attacks matching this Mega's type — so one Mega per raid party is almost always worth it. Stats and CP below are the Mega form's own.

DPS = damage per second · EPS = energy per second · DPE = damage per energy. PvP stats apply only to Trainer Battles, where 1 turn = 0.5 seconds. Type matchups use GO's ×1.6 / ×0.625 / ×0.39 scale.
