Starts in the bulky Shield Forme. The moment it uses a Charged Attack, it flips to Blade Forme (offensive) right before damage is calculated, so the Charged Attack lands with high Attack. It reverts to Shield Forme when it uses a Protect Shield or switches out.

• •Shield Forme stats — ATK 97 / DEF 291 / STA 155 (very bulky)
• •Blade Forme stats — ATK 291 / DEF 97 / STA 155 (Attack and Defense exactly mirrored)
• •In Shield Forme its Fast Move becomes a 0-power (1 dmg), 6-energy charging animation
• •No specific move triggers the change — ANY Charged Attack flips it to Blade

Starts in its Disguised Form. It fully nullifies the damage of the first Charged Attack it takes (0 damage, once), then changes to Busted Form with a permanent −1 Defense for the rest of the battle. On top of your two shields, that "one more block" effectively acts like a third shield.

• •Only the first Charged Attack is blocked — Fast Move damage still lands
• •After the block it gains a permanent −1 DEF debuff
• •Currently a top Great/Ultra League pick (Fast Move: Shadow Claw)

Starts in Full Belly Mode and flips between Full Belly and Hangry every time it uses a Charged Attack. Its signature move Aura Wheel changes type with the mode — Electric (Full Belly) vs Dark (Hangry) — letting one Pokémon poke two different weaknesses.

• •Aura Wheel — 100 power, raises the user's Attack by 1 stage (self-buff, no self-debuff)
• •Only Aura Wheel's type changes with the mode — the Pokémon's typing (Electric/Dark) and stats stay the same
• •Mode flips on each Charged Attack
• •Active only in GBL and Team GO Rocket battles; reverts to Full Belly outside battle
