Make your own ability!

[Caldoran]

Monotone
- Sound-based attacks do only 50% the damage, but have a 60% chance of making the opponent fall asleep

Lucky
- Moves have 20% more chance of hitting, and non-effective moves have a 10% chance instead (e.g. Ground on Ghost)

Charisma
- Sound-based attacks do twice the damage, but have a 60% chance of increasing the opponent's attack and speed greatly

[PokeSurfer]

First Strike - The Pokemon is always the first one to attack at the start of a battle.

Last Thoughts - When the pokemon is knocked out, all of the oppenent's stats sharply fall.

Double KO - If the pokemon is hit by a OHKO move, the foe also faints.

Independent - The pokemon is unffected by Perish Song or Destiny Bond.

Icy Skin - May freeze the foe on contact.

[Laprabi]

Flash Flood

All Water Type Attacks do 50% more damage. The user takes 50% more damage to all Grass or Electric Attacks.

[PokeSurfer]

Sudden Death - When the pokemon is in red HP, the opponent's HP is reduced to the same as yours.

Yeah, that would be an uber level ability. It would be tough to beat.

[Laprabi]

Yeah, that would be an uber level ability. It would be tough to beat.

Priority or something faster or Shedinja would own it.

[Alllister]

Nocturnal - The user falls asleep in sunlight, and if the user has a status condition already, the condition is replaced with sleep.

[+anima: Cooro]

Terror gase
makes the opponent uncomfortable and will slowly loose hp and may become confused.
doesn't affect bold/brave natured pokemon.
regret
lowers the opponent's defence/attack everytime the person is hit.
petal dance
grass types get rid of any status problems after battle

[PokeSurfer]

Aimless Strike - When the 1/3 or less of the Pokemon's HP remains, attack strength is doubled, but accuracy is halved.

A bit like Hustle, but with any attack.

Suicidal Blast

If an attack ends up killing the Pokemon that used it (e.g. Explosion, or Take Down while on 1HP) then the strength of that attack is doubled (e.g. Explosion goes from 250 to 500)

That would be really broken with Explosion. When you use Explosion it halves the opponents defense during the attack, so imagine how painful it would be? D:

That would make a STAB'ed Suicidal Blast Explosion 4000 base power.

could anything survive that? ( excloding ghosts).

[Webby2]

That would make a STAB'ed Suicidal Blast Explosion 4000 base power.

It would be 2000 base power, as it would be 250 x 2 (Ability) x 2 (Defense drop) x 2 (STAB) = 2000

Still powerful though.

Refuge or not

when at 1/3% hp it either does 90% dmg or 130% dmg when attacking.
(random affect)

[PokeSurfer]

Full Range: When the opponent uses Dig/Fly, the pokemon's attack will still hit.

[Apprentice]

Apathy

Three effects:

Effect One: When the user is struck with Attract, Captivate, Fake Tears, or Helping Hand, the user will be unaffected.
Effect Two: Return and Frustration's Attack power will be halved when the user uses them.
Effect Three: When the user uses Fake Tears, the opponents Sp. Def will be lowered by three stages instead of two.

Pretty useful at times. Effect Two is probably the best part of the ability for capturing Pokemon.

[Poseidon]

Hasty

Any two-turn moves used is played out on the first turn. This doesn't affect Hyper Beam and the like, so a turn will still be missed afterwards.

[Dandelion]

Reflection

Any status drops suffered by this Pokémon are automatically passed onto the opponent (includes drops caused by Intimidate, etc.).

Resolute

As HP drops to 50%, Def and Sp. Def are raised by one stage. When HP reaches 25%, they increase another stage.
