The Purification Chamber

Searched the board, surprised I couldn't find anything like this.

Okay, one person will post a Pokemon, and the next person will post a Pokemon who has one type that is at least 2x effective against the last Pokemon.

Ex:
[Jynx]
[Charizard]
[Rhyperior]
[Meganium]

So, the beginning Pokemon is:

Azelf.

Sneasel!

Sneasel's dark type, and I believe it's powerful against psychic.

Oh ho ho.

Lucario! 4x weakness and a 2x weakness, top that.

Uh..... Zeeky boogy doog!

Oh, I know, it's arceus with the mind plate :P

Purugly, how about that? =]

Machamp pwns Purugly with his almighty fighting STAB!

Always fighting O_O

Well, i'd say Staraptor (Jekyll, since our cockatoo sounds EXACTLY like him)

And I'll say Jolteon BRRRRRRZAP!

I'll go with Dugtrio. Eat that in your sandwiches!

Fine Ludicolo, Go! Clap that thing to death.

go! raichu! pwn that ludicolo! (couldnt think of nething else, ludicolo doesnt have many type disadvantages)

Aaaaand I send out Phanpy!

Empoleon (it's rock or ground, right?)

Go Cyndaquil XD He's fire so he can kill Emploeon since it has steel in it. but Cynda can also die from it's water attacks T.T

And out comes... RELICANTH!

Out comes Oddish! 4x weakness ftw!

and out comes charizard 2 kill ur little oddish! ^_^

How could you use Charizard against me? *sob*
Blastoise, dinner time!

raichu strikes again! :D
mwahahaha! :D

And Marowak annihilates it with "Enter Ground move here"
