ExtraPixelmon

This mod enables Eternatus to undergo Gigantamax. First, you need an item called the "Eternamax Candy". Right-clicking with this item can transform a regular Eternatus into a Gigantamax-capable Eternatus. After that, using a Max Soup on Eternatus will make it Gigantamax.

When Eternatus Gigantamaxes, it gains an exclusive Gigantamax move. This move is a single-target attack that can reset all the opponent's stat changes to their original state.

Gigantamax Eternatus also acquires a new Ability called "Gigantic Imbalance". The effect of this Ability is: at the end of the turn, if it is not at full health, it will restore to full health; if it is at full health, it will raise its Speed, Attack, Special Attack, Special Defense, and Defense by one stage each.

The way to obtain the Eternamax Candy is by challenging an NPC trainer. Defeating this trainer will reward you with an Eternamax Candy. The trainer spawns in a surface structure within the plains biome. First, to get a Deoxys with Super Transformation, we need a mysterious meteorite. Right-clicking this meteorite can transform an ordinary Deoxys into one with the new ability. It loses the Skill Swap move in battles. The description of the Super Transformation ability is: it enters the Speed Form at the start of a battle, switches to the Attack Form when using an attacking move, and changes to the Defense Form when using a status move.Ogerpon spawns in lush caves and can appear in four different forms. If you want to summon it directly, use "rainogerpon". Additionally, a bug in version 9.3.8 that caused crashes when viewing Pokémon photos has been fixed.
