For some strange reason, the majority of Gen IV escapes my mind. Not sure as to why. I mean, I had and played Platinum, but I barely remember any of the Pokemon except for the starters and my favorites.
Sealeo. I didn't even remember it existed until a Youtuber obtained one in his Emerald Nuzlocke.

Most Gen 2 Pokemon for me... Sometimes, some non-popular Gen 1 Pokemon receive the treatment too (Venonat, for example...)
Mantyke is the only Pokémon I keep on forgetting despite the fact that it looks adorable.
Dunsparce, I've not played 2nd Gen much , but this pokemon is the most forgettable.
Smart enough to use forth in the wrong context
Claims: Metagross and Travis Touchdown
Qwilfish. I keep forgetting about it until I have to complete a Dex. I think it slips my mind because it has such a low encounter rate and I never use it in-game.

Oddly enough, usually, the first two Pokemon that come to my mind after thinking about something else completely unrelated are Dunsparce and Delibird. I've actually used Dunsparce before, and it was unexpectedly useful.
