Mega Gengar Raid Guide
The best counters, weaknesses, and catch CP for beating Mega Gengar in Pokémon GO raids — computed from every attacker's stats and movepool in our imported game-data snapshot (dated below the counter table).
Best counters
DPS and estimated total damage output (TDO) are computed against Mega Gengar's actual typing and Mega boss stats — each attacker's best fast + charged pairing, ranked by the combined DPS³ × TDO score. Legacy marks movesets that need an Elite TM. Shadow forms exist for Mewtwo — a Shadow version deals ×1.2 damage (~20% harder) but also takes ×1.2 damage. This is per-boss matchup math, not the neutral-target tier list. Full formula on the methodology page.
