If you could have 3 Pokemon

[Isabella]

Just 3? Why not 6? =/
Espeon, Lapras, Dragonite.

 

[MyLifeIsCake]

Why would someone only pick three? (Gotta catch 'em all!) ; A ;

But they would be... Vulpix, Cyndaquil, and Eevee. I haven't played pokemon in forever though, so I dunno about the new ones

 

[Silversea]

Absol
Vaporeon
Latias

No specific order.

 

[EpicGamer12]

Ooooooh
Crobat, Wailord, and Torkoal.
Imagine the possibilities!

 

[Hound00med]

Houndoom, Togekiss and Empoleon.. EVERY time

 

[Paint]

My Oshawott for cuteness
An Absol to bring bad luck to my enemies
and an Emolga... also for cuteness.

 

[Littlemyuu]

Sceptile, Manectric, Quilladin

 

[kurisu]

Lucario, lilligant and arceus

 

[StiX]

Charizard, Scizor, Carracosta.

 

[thunderstar100]

I would now choose Mega Gardevoir (the leaked image, not sure if real) it looks very awesome.
I would also choose Dedenne and Mega Mawile.

 

[Midoriya]

For XY Pokemon probably Sylveon, Noivern, and Malamar

 

[keybug55]

Mew
Salamance
and Charazard
