Detailed Mechanical Explanation

For Discord/reference use

REGENERATOR is a passive healing ability that activates upon switching out of battle.

Activation Mechanics:

• Trigger: When the Pokémon exits battle (onExit hook)
• Requirements: Pokémon must be alive (not KO'd) and below maximum HP
• Healing Amount: Exactly 33% of maximum HP (1/3)
• Script: Uses tryhealpercenthealth BS_ATTACKER, 33 for consistent healing calculation

Switch Scenarios:

1. Voluntary Switch: Player manually switches Pokémon - healing triggers
2. Forced Switch (Moves): Roar, Whirlwind, Dragon Tail, Circle Throw - healing triggers
3. Forced Switch (Items): Red Card activation - healing triggers
4. Pivot Moves: U-turn, Volt Switch, Flip Turn, Teleport - healing triggers
5. KO'd/Fainted: No healing occurs (blocked by IsBattlerAlive check)
6. Full HP: No healing occurs (blocked by BATTLER_MAX_HP check)

Interaction Rules:

• Entry Hazards: Regenerator heals first, then hazards damage on switch-in to new Pokémon
• Status Conditions: Healing occurs regardless of poison, burn, or other status
• Pursuit: If hit by Pursuit while switching, healing still occurs if Pokémon survives
• Natural Recovery: Some Pokémon have this combo ability (Natural Cure + Regenerator)

Technical Implementation:

constexpr Ability Regenerator = {
    .onExit = +[](ON_EXIT) -> int {
        CHECK(IsBattlerAlive(battler))
        CHECK_NOT(BATTLER_MAX_HP(battler))
        BattleScriptCall(BattleScript_RegeneratorExits);
        return FALSE;
    },
};

Competitive Applications:

• Defensive Pivoting: Essential for bulky Pokémon that switch frequently
• Stall Teams: Provides consistent healing without items or moves
• Pivot Strategies: Combines excellently with U-turn/Volt Switch for safe switches
• Hazard Management: Helps offset entry hazard damage accumulation
• Longevity: Extends battle presence without requiring recovery moves

Common Users:

• Slowpoke line (Natural regenerative abilities)
• Ho-Oh (Legendary phoenix regeneration)
• Various defensive Pokémon as innate abilities

Strategic Notes:

• AI Value: Rated 8/10 in AI switching calculations
• Timing: Healing occurs immediately upon exit, before any entry effects
• Stacking: Cannot stack with itself, but combines with other healing sources
• Prediction: Forces opponents to consider immediate KO vs. allowing healing

Version History:

• Gen 5: Introduced as 1/3 HP healing on switch-out
• Elite Redux: Maintains standard 33% healing rate, expanded to more Pokémon as innate abilities
