What's your favorite shiny Pokemon?

Personally I really like Victinis despite being unobtainable.
From a yellow red to a silverish lighter red color just looks a lot better. Just looks like it represents victory more to me over the yellow although I guess it could be seen as the normal the gold medal and shiny as the 2nd place silver medal.

I'm not sure what I would say my favorite is, but Ditto, Mew, Dratini, and Rayquaza immediately come to mind as Pokemon with really awesome shiny sprites. Honestly, I think I might go with Dratini. The pink is so cool. Then it becomes so lame when it evolves into Dragonite...

My favorite is Greninja I spent so long trying to Masuda method one in gen 6 games just to get it with no shiny charm or anything whike working on the dex in ultra moon now he's in my box in Scarlet.

My favorite shiny Pokémon is Espeon, I love the green, and it fits male Espeon's prefect. I do also like Mewtwo's shiny or Feraligatr's shiny.

I'm fond of a shiny Flygon. Some bugs like Venomoth and Mothim also have pretty shinies.

And well my username is colored after shiny Furret so throw him in there as well

There are quite a few shiny Pokémon I like, but here are some of the most noteworthy:

Haxorus– Already a really cool Pokémon design made even better with a black and red color scheme.

Greninja– Again, another very solid design made better with a black color scheme. It also fits Greninja's ninja motif perfectly.

Sylveon– The regular and shiny sprites are both good, but I like the cotton candy color scheme the shiny has. Very fitting for a Fairy type.

Gigalith– The shiny is much more striking than the regular version, and stands out among the usual gray, brown, orange, and black hues Rock types usually have.

Rayquaza– Not much to say here, shiny Rayquaza is just perfection.

Giratina– Same as Rayquaza, this shiny just works really well.

Metagross– The silver and gold work really well with the red eyes. Makes me think of Megatron a bit.

Gardevoir– The shade of blue for the shiny is very aesthetically pleasing. I don't like the way the puffy black dress looks when it mega evolves, though.

Some other shiny designs I think are top tier include: Glaceon, Aggron, Xerneas, Absol, and Suicune. If any more come to mind, I'll add them here.

My favorite would probably be Zoroark. I just really like the color palette. I also love the shinies for Shinx, Lucario, Charizard, and Gardevoir.
