Scizor
Bisharp
Gyrados
Honchkrow

 

[BballLuke13]

My most valuable has got to be my shiny level 100 6IV Serperior. Traded Zekrom for that thing. 2nd through 5th place go to the rest of my shinies, Aegislash, Amoongus, Ursaring, and Zoroark.
As for my favorite Pokemon, that's Lapras.
Though, the Pokemon I've had the most success with in battle is either my Snorlax or Yvetal.

 

[mokonasakura]

My shiny absol, my leafeon, my ninetales, and my near perfect swampert are the most valuable to me. I never really liked or disliked swampert but when i picked him up and started using him for competitive play he has pulled me out of a lot of tough situations. A pokemon that will be traveling with me in all of my future adventures for sure.

 

[Talon Flare]

My shiny Mamoswine caught as a Swinub 4 years ago in Soul Silver. That was the only shiny Pokemon I've obtained without training.

 

[Rueroms]

My most valuable Pokemon would have to be Fernanda, my shiny Scrafty. I was just hatching eggs like crazy to get some decent IV's, and then she popped out. She's my forever girl.

 

[Heir]

I spent a long time in X and Y getting shinies, and I managed a couple. But my most valuable would probably be my shiny Aegislash, considering a lot of people want one.

 

[Pendraflare]

This can be interpreted one of two ways. If we're talking something nice that I obtained or bred, I don't know, i've bred quite a few Pokémon in my main game of X and there aren't any I would say are as rare or prized for me as others.

But when it comes to playing through the story, my most recent play of X had a few - my Klefki for one mustered through quite a few difficult fights with Prankster + Calm Mind + Substitute, while my Tentacruel and Medicham had been with me since after the fifth Gym and they were still alive after the end.

 

[Aisu]

For in-game, Golurk has always been my rock, hehe. For Wi-Fi, I'm caught between my Lanturn and Charizard Y.

 

[Ephemeral Euphoria]

For me, it would have to be this Charizard of mine that I've hung onto since 2008 back when I still played Fire Red. Well, that and a shiny Geodude of course.

 

[Rayheart]

For Value, probably my 6IV Shiny Female Garvedoir.

 

[Simmo0916]

My most valuable is a Charizard I have had since Pokemon Platinum. It was a long job transferring all my old Pokemon into X/Y, but It's finally done! Some of these pokemon are 6 years old :D

 

[Polar Spectrum]

Ditto whomever above said "I don't have an MVP, I have several."

They're not necessarily my favorite pokemon (although some of them are... mismagius but they are my most valuable.

My 4 Gengars with 5 IV's and all varying movesets for tripping people up.
My 6 IV Roserade who tought me there is things to love about fourth gen.
My 3 6 IV Mismagiuses... Mismagi? Mismagius'? Idunfuggnknow. I have 3 Mismagius. They're all perfect. All play very very differently in battle too, which makes them extremely invaluable to me.
My Stunfisk, whom is always underestimated, and always makes me proud.
My Mandibuzz, who always hangs around in battles.
My 2 Scraftys, who have pulled me out of more 1-sided matches to victory than I have battle videos of them saved doing so.
My Dunsparce, who's shown me Uber users online in X/Y can be beaten by their own lack of knowledge.
And my Vileplume, whom I have witnessed be reincarnated, ever generation since Red and Blue, to Yellow - since 1998, and gained a lovely new trick in Black and White, in finally being a dangerous flower just to touch.

 

[Braxien]

My most valuable Pokémon would have to be my Braixen. Why? Look at my username. ;)

 

[Mega Venusaur]

I wouldn't say that any of my Pokémon have any 'value', seeing as I am still progressing through the storyline of the main game. However, my strongest Pokémon would have to be the Level 67 Charmander which was given to me by Cakesu.

 

[Cariad]

I don't have any valuable Pokemon in terms of shinies or IVs, but I have a Leafeon that I've used on every game since I hatched it in Pearl, so it's a pretty important Pokemon to me.

 

[captainfez3]

My most valuable Pokemon usually ends up being my starter, although I was really fond of this Umbreon I got in Gold for the first time.

In reality though, my MVP would have to be Sceptile. I cannot wait to get a team back together with him in it in AS. I know I could have one now, but it isn't the same!

 

[987Theawesome]

My Shiny Latios, called Minty, straight out of my copy of Black 2.
I caught it legit from soft resetting, it was my first soft reset hunt (Im now on my second, Latias), and Latios is my All time favourite pokemon.
As far as stats go, my Shiny Latios isn't all that special, but still, I damn love it.

 

[elnoor]

My most valuable pokemon is my 4iv timid movie event Japanese darkria 2014.

 

[bewbs]

My in-game bellossom called Lily. She's so useful in horde ev traning

 

[Bounsweet]

Pretty much all of my IV bred Pokémon, all of my really good events, etc.

I love the Xerneas I caught in my last X playthrough though, Timid nature with perfect IVs in HP, Special Attack, and Speed. The remaining IVs are like 24+ in Defense and Special Defense, I think. I didn't soft reset or anything, just got extremely lucky!
