Protosynthesis (Ability)

Protosynthesis	こだいかっせい
	Ancient Activation
Flavor text Generation IX Boosts the Pokémon's most proficient stat in harsh sunlight or if the Pokémon is holding Booster Energy.

Protosynthesis (Japanese: こだいかっせい Ancient Activation) is an Ability introduced in Generation IX. It is the signature Ability of the ancient Paradox Pokémon with the exception of Koraidon.

Effect

In battle

	This Ability effect may be in need of research. Reason: Check for other moves/Abilities that can or cannot copy/replace/suppress this Ability. Usual suspects: Simple Beam, Power of Alchemy, Mummy. You can discuss this on the talk page.

When a Pokémon with Protosynthesis is in harsh sunlight or is holding Booster Energy, its highest stat (other than HP and taking into account stat stages, but not held items) is increased by 30%, or 50% if Speed is the highest stat. Upon activation, a message tells which stat is increased to all the players. If multiple stats are tied for highest, Protosynthesis breaks the tie by prioritizing physical Attack, physical Defense, Special Attack, Special Defense, and Speed, in that order.

Protosynthesis will activate in harsh sunlight even if the Pokémon is holding a Utility Umbrella. Harsh sunlight will activate Protosynthesis before a held Booster Energy, so the Booster Energy will not be consumed if the Pokémon with Protosynthesis is in harsh sunlight.

Skill Swap and Doodle will fail if either Pokémon has Protosynthesis. Worry Seed, Gastro Acid, Role Play, and Entrainment will fail if the target has Protosynthesis. Protosynthesis cannot be copied by Receiver or replaced by Lingering Aroma.

Outside of battle

Protosynthesis has no effect outside of battle.
