Basically you just use your avatar's powers [mine is Mew] to kill the user's avatar above you.

Example:
Person with a rabbit avatar: Hi
Me: I use Blast Burn on your vulnerable spots

You get the idea.
So let me start: I use my psychic powers on the invisible user above me and attack his weak spots

Murkrow Used Quash! It's Super Effective!

Gliscor used Stone Edge! It's super effective!

Deoxys used Focus blast it was super ultra mega special chocolate effective

Was that really super ultra mega special chocolate effective? Wow, you really Destroyed him!

I, once again, will use Quash. It wasn't quite enough so I ued it once more

Emolga used Thunder!

...

It's Super Effective!

Honchkrow fainted!

TP sent out Le Mask!

TP used a Max Revive!

TP recalled Le Mask!

TP sent out Honchkrow!

In an air duel Emolga and Murkrow had a ********... Emolga was quicker but Murkrow was stronger...Murkrow used many dark and flying moves to quickly end the battle.

This time it was between Gliscor and Murkrow. With Gliscor's toxic and protect stalling techniques, he just trolls the whole metagame. He won.

Deoxys walked up and turned into attack form to do more damage then used thunderbolt and gliscor went boom

Deoxys rage quits and throws controller into gliscors face making it fall to the earth.

TurtwigX calmly states that your arguments are invalid and slashes at you with his Leaf Blade X.

Gliscor used Acrobatics! Turtwig died.

Emolga used a Max Revive and brought Turtwig back to life.

Phantom barely withstood a Thunderbolt + Leaf Storm combo attack, and fainted hard.

Pichu randomly jumps into battle and uses Sweet Kiss on everyone!

Emolga got hit on the lips, and used Attract in revoltion!

Emolga targeted Oshawott with it, but Pichu jumped in the way!

TurtwigX quickly uses a TM and calls on a Blizzard to envelop Emolga!

Deoxys smacks TurtX upside the head then uses hyper bean to destroy him

TurtwigX wraps Deoxys up in its own long arms and kicks it into Dark Crater.

Deoxys flys up drops a boulder on turtx

Demyx smacks Deoxys in the face with his water guitar.

Emolga plays one note on Demyx's guitar, somehow encasing it in about 12,000 volts and giving him major shock burns.

Pichu jumps onto Deoxys' back and uses Discharge shocking him an everything around him!

Deoxys gets mad because pichu attacked him instead of emolga so he obliterates it with rapid hyper beams.

Demyx suffocates Deoxys in water.

I gouge your eyes out with my talons!
I am a violent Murkrow.

Lets Tharja kill the Murkrow in its sleep.

They look so cute together it almost feels like a crime to think about killing them.
Oh well.
TurtwigX launches a massive Fire Blast at the two, burning them alive!

Gliscor picked up Turtwig and flew up to space and dropped it on it's head.

TurtwigX spun Gliscor by his tail and flung him into an iceberg!

Squirtle102 used Ice-Beam!

TurtwigX spammed grass moves to kill him till he's dead!

Using my infinitely sexy looks you are momentarily stunned, the time in which I use my heat vision to incinerate you.

Emolga used Attract and...out-sexied...Ningamer.

Lúthien used her magic dancing to put Emolga to sleep, and then smothered it.

Pure used his bike to ride over Tarellethiel!

Lúthien used her charms to convince Arceus to deal Judgement to Pure.

Mega charizard used flamethrower on Turtwigx! It's super effective!

Mega Charizard wants to battle
Go Technochu!
Technochu used Angry German Kid!
Mega Charizards Headphones broke!
Its Super Effective!
What! Gavintendo64 is evolving!
