Pokemon for a day

[Lambi]

Charizard. Because he's my favorite Pokemon and he's awesome.

 

[skittlepie345]

I'd be Eevee. But more importantly, I'd be Gary's Eevee.

 

[Jark212]

SANDSLASH!!! So I could dig a elaborate series of tunnels around my town for my personal use...

And a underground fortress...

 

[The Shade of Time]

Abra just so i could show up and be all like "LATER BITCHES" and the POOF gone.

I'd piss so many people off in one day.

 

[Mr.Valdor]

Squirtle. I've always loved Squirtle.

 

[Patricius]

Gardevoir, because it's my favorite. Or maybe Gallade. Possibly Dan Green-Entei.
EDIT: Ninja'd on the Dan Green...

How about Metagross? It has the brain power of four supercomputers, can fly, and I doubt that anything that isn't flame or ground based could bring much harm to me. :3

 

[Spiner909]

Beedrill, so I could scare people into trying to use RAID on me.
It won't work. MUAHHAHA!

 

[Omega V]

Mew, Mew all the way. There is no way I would pass up a chance to be awesomeness incarnate. I would likely spend the first few hours flying around the earth simply having fun and otherwise enjoying myself. then I would go to screw with some military for awhile, like flying circles around some befuddled fighter jets, then do something that might actually benefit somebody. plus i imagine that being an adorable cat-like creature would have other interesting benefits, so i would find a group of attractive young women and let the fun begin.

 

[Ithera]

A Bidoof. So all those pesky pokehunters would leave me the F&%C alone. I don't want to spend the rest of my life in a pokeball.

 

[OceanRunner]

Blaziken.

Because I will roundhouse kick anyone who dares calling me deformed nuclear Kentucky Fried Chicken.

Second.
Who wouldn't want to be a martial arts birdman that blasts fire?

My other choice would be Pachirisu. Everyone loves a cute, cuddly, fluffy-tailed squirel.

 

[jboking]

Nidoking. Then I could run up to my friends, hug them, and then accidentally poison them. I would raise my nidofists in the air and shout, "WHY MUST I HURT THE ONES I LOVE!"

 

[Strykz]

Gallade.

 

[Generator]

Pikachu, of course. Not only would I be the most recognizable Pokémon, but I'd get all the chicks too because I'd be so darn cute.

 

[DefunctTheory]

Spoiler: Very Gross, But Money Making Answer

Venusaur.

Venusaur+Female Cast+Camera Man=Rule 34 would make me an over night millionaire.

Just for fun?

Gengar. Time to scare the crap out people.

 

[Embz]

Rapidash cos its a horse but with fire

 

[Claude_Raines]

Gallade - a psychic fighter with blades for arms. Hells yeah.
