Meowth thats right

Ahem! Mewtwo, Lugia, Slowking, Entei... Just to name a few...

Mewtwo, Slowking, Entei, Lugia, Jirachi, Lucario, Zorua, Reshiram, Zekrom, Arceus, Manaphy, Darkrai, Hoopa, Volcanion, those are the ones that I remember
(Sorry for replying to everyone, I'm just a huge pokemon nerd)

I stopped watching the show after Misty left. Watched a bit with May, but dropped it completely with Dawn. Still play the handheld games, and PokéFarm, but that's it.

Question, does entei count? Because the only reason he could speak was because that's how Mi imagined him, it was the unknown spell, not really his ability

I remember him being smooth af

Not to mention the sweetest character in the show when not under Jessie's direct influence.

not attack moves, but learning Payday

He learned to talk to impress a female meowth that he had a crush on, who then left him for a handsomer meowth.
Also, I love your username

a persian
not a meowth

it's the most OP pikachu of all time though.
