Pokemon you often forget exist?

[Hawks]

hitmonlee and hitmonchan :P (don't ask why cause I honestly don't know :D)

 

[Random]

I mostly forgotten that unown existed, at one point.

and basically qwilfish, delibird, houndour/houndoom too.

 

[Radikaru]

I forgot a good chunk of the species from Gold/Silver/Crystal, since those games were on the bottom of my list (I didn't like them very much, haha).
But I remember most of them, to my knowledge.

 

[The Real AAA]

I forget mostly of the Hoenn pokemon because I'm not used to it in that region

 

[Poke Power]

All the new Pokemon. Their names are weirder and harder to remember but I also think it has something to do with me liking the older Pokemon seasons better.

 

[Lone--Wanderer]

I have yet to actually forget a certain Pokemon.
