Support Pokémon Definition

A Pokémon is classified as Support by the AI if it satisfies the following conditions:

• The Pokémon has at most one damaging move.
• The Pokémon has no moves with base power > 75.
• Pokémon with Imposter are excluded.

These moves are treated as utility and do not contribute toward the damaging move count:

• Fake Out, Feint, Upper Hand
• Endeavor, Super Fang
• Dragon Tail, Circle Throw
• Knock Off
• Foul Play
• Future Sight
• Bug Bite
• Pollen Puff
• Speed control (e. g. Rock Tomb, Glaciate)
• Surf and Dive (only when the user is a Cramorant)

The support class plays a notable role in some Switch decisions.

Post-KO Switch AI Scores

When the AI needs to switch in a Pokémon (after a faint or similar event), it calculates a switch-in score for each of its Pokémon against the player's active Pokémon. It will then send out the Pokémon with the highest score. In case of ties, it selects the first Pokémon in party order.

In Double Battles, each slot is evaluated independently:

• The AI’s first slot evaluates against the player’s first slot
• The AI’s second slot evaluates against the player’s second slot

+5: AI's Pokémon is faster than the player’s and OHKOs it.

+4: AI's Pokémon is slower than the player’s and OHKOs it.

      (Or AI considers Palafin-Zero)

+3: AI's Pokémon is faster than the player's and KOs in ≤ hits.

      (Or AI considers Imposter Ditto)

+2: AI's Pokémon is slower than the player's and KOs in < hits.

      (Or AI considers Wynaut or Wobbuffet)

+1: AI's Pokémon is faster than the player's.

  0: Default

 -1: AI's Pokémon is slower than the player's and is OHKO’d.

      (If Imposter Ditto is considered, this check is skipped.)

If the considered Pokémon is a Support and isn’t at -1 Score it gets an additional +2 score 10% of the time.

Additionally, the AI checks whether the Pokémon will take damage immediately upon switching in (e.g. from fast Volt Switch or Eject Pack). If so:  

-1: AI's Pokémon is slower and 2HKO’d

-2: AI's Pokémon is OHKO’d

Mid-Turn Switch AI

In almost all cases, the AI will only switch if the selected Pokémon has a non-negative switch-in score. If all available candidates have a score below 0, the AI will not switch. Similar to Post-KO Switch AI, each slot is evaluated independently in Double Battles.

Some switch conditions require the Avoid Switch check to fail before they can trigger.

Avoid Switch is considered active if any of the following are true:

• The AI has boosted stats
• The AI can KO one of the player’s Pokémon
• The player has access to moves that force a switch or double in power after a switch (e.g. Roar, Dragon Tail, Pursuit)

Switch decisions are evaluated in priority order.

Earlier conditions override later ones.

Overview of Switch Conditions

The AI will not switch out without a valid switch-in unless it’s:

• Anti-Setup AI Plus

The AI will send in the Pokemon with the highest Switchin Score, with Team order as a tiebreaker, except for:

• Anti-Setup AI
• Anti-Setup AI Plus

The Avoid Switch check is used for the following AI’s:

• Walled AI
• Support AI
• Weather AI
• Anti-Stall AI
• Regenerator AI

Move AI will be documented soon in another Doc. Since Round AI has been changed in 1.2.1, it will be elaborated here and edited out later.

Score Priority overview:

The following provides a high-level overview of how maximum move scores are prioritized within the AI logic. This list is not exhaustive and is only intended to illustrate the general hierarchy and relative score priority of different decision outcomes.

• Tier 1:

• Fast kill
• Sticky Web
• Palafins Flip Turn
• If frozen: Moves that thaw the user
• Damaging Gimmick moves (Feint, Upper Hand, Beat Up, Round, Weakness Policy activation, Pursuit, if user has a negative ability and target has a Mummy-like ability)
• Protect (For form changing gimmicks)

• Tier 2:

• Slow kill
• Field moves:

• Trick Room, Wonder Room, Magic Room, Gravity,
• Hazards, Tailwind

• With Power Herb: 2-turn moves with powerful side effects (Geomancy, Meteor Beam, Electro Shot, Sky Attack, Freeze Shock, Ice Burn)
• Boosting a partners stats

• Swagger and Flatter if the partner will not be confused
• Coaching, Decorate

• Status Gimmick moves (Psych Up, Role Play, etc)

• Tier 3:

• Highest Damage move (HDM)
• Status moves
• Damaging moves with guaranteed side-effects (doesn’t stack with HDM score)

Round (Double Battle only):

To understand Round AI, it is important to first understand how partner move scoring works in Double Battles.

Score calculations are processed sequentially. The AI first calculates all move scores for Slot 1 without knowledge of what Slot 2 will select. Slot 2 then calculates its scores afterward, while being fully aware of Slot 1’s chosen move and resulting score.

Round-specific scoring behaves as follows and stacks with HDM:

90% of the time, if the AI is faster and its partner has access to Round:

• +7 Score
• The partner’s Round score is overridden to +13

Warning: If the faster Round user is in Slot 1, the partner in Slot 2 has not yet calculated its scores at the time of the override. As a result, the override has no effect in this scenario.

If the AI is slower and its partner selects Round:

• The slower user receives a +13 score bonus.

Warning: If the slower Round user is in Slot 1, it cannot yet know whether Slot 2 will choose Round, since Slot 2 has not performed its calculations yet. To compensate for this limitation, the previously mentioned score override is applied instead.
