Treecko! It’s shiny palette is elite & looks best in the pixel games. I also own a copy of Treecko Gold Star. It’s a bit disappointing to see it not look so obviously shiny, though.
Number 1 is probably Trapinch, they made him Cadillac Green in XD instead of the turquoise and it looks just as good. Basically if it’s green, turquoise, pink and/or particularly monochrome, I most likely love it.
To be honest it’s just a pity that the majority of pokemon have a shiny color that feels so random. A lot are just so similar like garchomp or gengar, many are just green or pink lol.
I understand the hardware was a limiting factor back then, but it would be awesome if they rethink all those lame variants and choose a cool hand picked palette
I stopped Pokemon before shiny were a thing, then when I cam e back for PokemonGO I learned about them. I think Dragonair is my favorite shiny and tied for favorite Pokemon with Gastly. Purple is my favorite color so Lapras I choose you then Heracross just looks cool. I don’t think they have any cards shiny of them though. I like all the shiny Pokemon that are a lot different looking though.
