Gengar-Mega is listed as a Ghost/Poison type in the current Pokémon Champions format, with usage data pulled from competitive teams, tournament results and Showdown-ready pastes tracked by MetaVGC. This page brings together its most common moveset, nature, ability, item, teammates and type weaknesses so you can judge where Gengar-Mega fits in a VGC team.
The most common build highlights Shadow Tag, Gengarite and Timid 2/0/0/32/0/32. Its frequent moves include Protect, Shadow Ball, Sludge Bomb, Perish Song, Disable, and Icy Wind. Treat those choices as a data-backed starting point: they show what players are bringing, while EV spreads, Tera Type and the final move slot should still respond to your expected matchups.
Defensively, Gengar-Mega has important weaknesses to dark 2x, ghost 2x, ground 2x, psychic 2x. That matters during teambuilding because a strong composition needs ways to cover those attacks without giving up offensive pressure. Partners such as incineroar, kingambit, sneasler, ninetales-alola, and sinistcha appear often because they can add positioning, type coverage, speed control or safer switches into common checks.
