What do you think is the most forgotten Pokémon?

Grumpig and Swalot.

Heck, I didn't even know Swalot existed until my Gulpin evolved a few months ago O_O

Also, yep, Tyrouge and Dunsparce are very often forgotten (in G/S/C/HG/SS, you can only get Dunsparce in Dark Cave and Tyrogue only when travelling to the very ottom of Mt Mortar, which most people don't like to do).

Tropius has been forgotten by Pokemon Company, as has Absol, Heracross, Dunsparce, Tauros, Miltank, Minun, Plusle, Kangaskhan and many other single-form Pokemon.

Hopefully this'll be fixed in Gen 5, tho I doubt it.

I miss Snubbbull.

Yes, I remember all of those, SFG

However, I remember my surprise when my Clamperl evolved into Gorebyss... I do think those two, Huntail and Gorebyss, are forgotten.

But, moreso than Surskit, there's Masquerain.

I neer knew it existed until it was the only space left on my Ruby Pokedex.

(Hi. ...Back. ^^)

Ask any one to say all thew Pokémon in the Kanto region, and they'll almost always miss out Kangaskhan.
I've always thought that seemede rather forgotten in the world of Pokémon. They seem quite strong, too, so it seems a waste...

I used to be able to recite all of the Pokemon

Then it got to 3rd Gen

Spoiler:

I always forget about those last two.

I liek Ledian tho =(

I haven't forgotten her
