Only one, please. And add what you like about it!

Mine's Mew. She (he?) is soooo cute and powerful and since i like so many pokemon, mew can turn into all of them!

My'n is deffo Groundon

he is so cool and he is really srong

if not legendairy i love natu and xatu

Jigglypuff!!!! duhhhh

but if i had to pick out of the legendaries i would pick cresselia or mew

note: little pink mew and Ace Vantura pls dont double post;
id have 2 say manaphy and if not legendary maybe pikachu

INFERNAPE THE MONKEY RULES ALL!

My favorite is Vulpix. I thought it was soooo cute when I first saw it.

togekiss beat all of those, but i've got to say those pokemon are pokemon i quite like!

if i had to choose... rayquaza for legendary cuz its so cool, green, powerful and awesome! Plus it lives in the sky ^^

for non legendary i really cant choose... maybe eevee cuz it eveolves into many forms like leafeon!

O boy, this is tough. I would probably have to say, Charizard. He evolved from my first pokemon, and he is AWESOME! (Especially when he's shiny)

either togekiss, Rayquaza or charizard nothing else!

hmmm, i'd have to say Eevee. like that other person said, it evolves into so many different forms and its so cool. and my favourite legendary would have to be Raikou cause he is just so totally awesome!

Bellossom!!!
Why? She is THE BEST Grass-type in PMD!!!!
Here's mine

Bellossom @Persim Band
Type: Grass
Ability: Chlorophyll (Boosts attack frequency in sunny weather)
Friend Area: Jungle
Joined rescue team at: Sinister Woods
Flower Pokemon
Size: *
Evolution: No more
Moves:
Solarbeam
Sleep Powder, Petal Dance LINKED
Giga Drain

Persim Band prevents Petal Dance's confusion side-effect. Giga Drain restores HP, damage opponents, blablabla. Her main punch line is:

Sunny Orb + Chlorophyll + Solarbeam = Two Solarbeams WITHOUT charging in ONE TURN. It can't learn Sunny Day, which is a shame. But if you bring 3-5 Sunny Orb to a dungeon, her Solarbeam can rock out!!!
