Favorite Sinnoh Pokemon and why?

[AuroriumX]

Luxray, as can be seen by my banner.

 

[DarkSword39]

Piplup: It's so cute!

Darkrai: Favorite Legendary, It is also extremely strong. The Darkrai Movie is my Favorite Pokemon Movie.

Leafeon: Favorite Eeveelution, I used a team of all Eeveelutions and it was the best on it.

Gliscor: Was my favorite Pokemon at one time. Just the design and battling wise.

Honckrow: Along with Gliscor, was my Favorite Pokemon (replaced my its Pre-Evolution, Murkrow).

 

[Bramble]

My favorite legendary: Shaymin sky form. I just love the way it looks, and I love the high chance of flinching my opponent it has when using air slash. My favorite non legendary is Glaceon, and I like how it's colored. But my favorite Eevee evolution overall is Leafeon.

 

[UbersSuck20]

Weavile, definitely.

 

[Innocent Squirtle]

Lumineon: Because it is a serene-looking butterfly fish in a cool blue color.

Glaceon: The color scheme

Piplup: Cute and blue

Gastrodon (East Sea): Blue yellow and green

Manaphy:Same as Piplup

 

[ChloboShoka]

My favourite pokemon from Sinnoh is Vespiquen because I really love her design and I think she is a sassy pokemon.

 

[LiepardTrainer]

My favorite in Sinnoh, like in other regions, has to be the weasel or otter Pokemon of the region, and my main one for sinnoh is the "sea weasel" Pokemon, Buizel, and Floatzel too.

 

[Cyberra]

My favorite is Finneon ^^ I'm a fishkeeper (Siamese Fighting Fish/Betta Splendens), and I love butterflies. Finneon combines a fish and a butterfly. I love it so much I commissioned a pair of plush Finneons, and want at least two more.

 

[Reborn Cyrax]

Gallade. 100%. And now, Darkrai too.

 

[Canada]

I like most of the Sinnoh pokemon, my favorites are probably the starters.

 

[GoldenHouou]

Loved quite a few, but Staraptor hands down. It's a bird, it looks awesome and it's kick***.

 

[Monster Guy]

Hm, I thought I posted here already. :/

To be honest, most of my favorite Sinnoh Pokemon are the evolutions of existing Pokemon.

Roserade
Yanmega
Togekiss
Gallade
Froslass

The only original Sinnoh Pokemon I like are Shinx/Luxio/Luxray and Riolu/Lucario. The starters are ok too, but just ok. They're not my favorites by any means.

 

[☭Azimuth_055☣]

Garchomp, because it looks cool and it's a pseudo legend.

 

[Ashfer]

My favourite Generation IV Pokemon is Luxray. It's so cool.

Not only do I like the colour scheme and the hairdo, but I like the stats too. My LUxray in Platinum has even Atk and Sp. Atk, which I think is really handy for diverse moves.
