PVP Meta – Zen Headbutt / Giga Impact

Regigigas is not suggested for PVP for now, as they have given him atrocious moves to weigh out his overscaled stats. If they ever give him Lock On it will be a different story

Raid Meta – Hidden Power Fighting / [Various Charge Moves]

Regigigas has such obsene stats he can function as a kind of PVE generalist at times, with him being a bizzare choice for anything he can hit super effectively. It is not suggested to spec him for this given how resource intensive it is, but you can find him popping up as an odd choice here and there. Giga Impacts insane damage also allows it to do a lot even in generalist scenerios.

There are a couple classes of unique pokemon that are more difficult to use than others, they have been filtered out here to not clog up the counters too much. These pokemon are much more resource expensive than other options.
 • Shadow Machamp– Best in General simulations.
 • Shadow Hariyama– Great in General simulations.
 • Shadow Mewtwo– Great in General simulations.
