I can name Sandshrew, Pikachu, Raichu, Bulbasaur, Venosaur, Charizard, Charmander, Charmeleon and many more.
If you don't want to type that much, you can just put the number of Pokémon you can name.

i would say 60 or something no more i think 100 (i m a poké-freak )

My head is filled with Raichus.So why couldn't I name them?
I could easily name 2000 at once!
Quickly I could tell the name of Clefairy,Zubat,Golbat,Charmander,Charmeleon,Dieno,Zwelious,Ponyta,Rapidash!

I think 100 if i just did it in my head

And here I have more!
10,000 outta my mind to you!

I'll give this a try.
   bulbasaur, charmander, squirtle, pidgey, pickachu, meowth, ekans, koffing, diglett, dotrio, ivysaure, blastoise, charmeleon, charizard. I could name many more but I don't want to try to spell them any longer.

hmm how many off the top of my head now that's for me honestly is almost 500 of them or more

I could name: Bulbasaur, Ivysaur, Venasaur, Charmander, Charmeleon, Charizard, Squritle, Wartortle, Blastoise, Caterpie, Metapod, Butterfree, Weedle, Kakuna, Beedrill, Pidgey, Pidgeotto. Pidgeot, Spearow, Fearow, Rattata, Raticate, Sandshrew, Sandslash, Pikachu, Raichu, Magnemite, Magneton, Magnezone, Electibuzz, Elekid, Electrivre, Magby, Magmar, Magmortar, Tangela, Tangrowth, Kangaskahn, Abra, Kadabra, Alakazam, Jynx, Smoochum, Gastly, Haunter, Gengar, Mewtwo, Mew, Articuno, Zapdos, Flareon, Eevee, Moltres, Vaporeon, Jolteon, Umbreon, Espeon, Glaceon, Leafeon, Gligar, Gliscor.

I could name most of the originals....but when it gets to the newfangled ones, I get all messed up for some reason. Possibly because I don't like the newer ones as much. I prefer the Gold and Silver versions on down.

a LOT i think something like 500 (from the 651 pokemon yes 2 more black and white kyurem)

I'd say about 100-150 Pokémon because I played Pokémon for six years already. Time flows so fast..

I could easily name about 200!

I can literally name all 649 Pokémon as I always see their names and research about them in my free time before I came here so I might forget some names but I can name lots of them but mostly the names in my head are pikachu, onix, charizard, lapras, genosect and all generation 1, 2 legendaries.

Pikachu , Blastoise , Charizard , Venasaur, Jolteon , Axew , Charmin , Pidgeot , Sandslash , Mewtwo , Mew ,Squirt le , Treecko , Trochaic , Mud kip , Skarmory , Chimchar , Snivy , Moth , Bellsprout , Tepig , Gastly , Haunter , Gengar , Jellicent , Mighyena , and Ditto.

I could name 414 of them theirs a few that I can't name such as finneon and relicanth I guess it's because not much trainers use them in Pokemon games
