Gigantamax Machamp

Pokemon GO's original Top Tier fighter reclaims its throne in Max Battles! Gigantamax Machamp deals ferocious Fighting-type damage with its powerful G-Max Chi Strikes; its raw power eclipses every other Dynamax Fighting attacker in the game (save for Dynamax Pheromosa, which could be years away from release). As a result, Gigantamax Machamp is a safe investment for all your pummeling needs.

Machamp lacks access to a 0.5 second Fast Attack to rapidly charge the Max Meter, but that's not a huge downside. Simply allow its tankier teammates to sponge hits and charge up the Max Meter. Then, when it is time to Dynamax, switch in Machamp to unleash devastation.
