While most Pokémon are capable of growing in size and strength due to Dynamax, there’s a step beyond that which only a select group of Pokémon species are able to attain — Gigantamax!
The Gigantamax phenomenon causes the Pokémon to grow to insane sizes and even change some of its physical characteristics, somewhat similar to Mega Evolution from previous games.
Gigantamax Pokémon
Below are all of the revealed Gigantamax Pokémon. You can click any of them to find out more about them, learn about their G-Max Moves, see pictures, screenshots, etc.
Keep in mind that just because a Pokémon has a Gigantamax form doesn’t mean that any of that species can go Gigantamax instead of ordinary Dynamax — according to the press release: “Only certain species of Pokémon can Gigantamax—and even among such species, only rare specimens will be able to Gigantamax. The majority of Pokémon will keep their usual appearance when they Dynamax.”

G-Max Moves
Gigantamaxing also unlocks exclusive G-Max Moves that are dependent on the Pokémon’s species, similar to certain Z-Crystals from the Alola region. These G-Max Moves require the Pokémon to know a move of a certain type, similar to Max Moves from Dynamaxing.
| Pokémon | G-Max Move | Effect |
| Corviknight | G-Max Wind Rage (Flying) | Damages the foe and removes effects of moves like Reflect, Light Screen, Spikes, Electric Terrain, and more on the foe’s side of the field. |
| Drednaw | G-Max Stonesurge (Water) | Damages the foe and scatters rocks on the field, similar to Stealth Rock (possibly the same effect). |
| Alcremie | G-Max Finale (Fairy) | Damages the foe and heals all Pokémon on Alcremie’s side of the field. |
| Charizard | G-Max Wildfire (Fire) | Damages the foe and also does damage to all Pokémon that aren’t Fire-type for four turns. |
| Butterfree | G-Max Befuddle (Bug) | Damages the foe and also affects all opponents with either poison, paralysis, or sleep. |
| Pikachu | G-Max Volt Crash | Damages the foe and also paralyzes all opponents on the field. |
| Meowth | G-Max Gold Rush | Damages and confuses the foe, as well as scatters a lot of coins after the battle to give the player Prize Money. |
