Who's your first "most used" Pokémon?

I'm a bit ashamed to admit, I got into Pokémon almost by accident. When I was little (I can't remember how old) I bought my very first gaming device, a GameBoy Color, and as I bought it from a boy who had had enough of it I got some games with it as well and one of them was Pokémon Yellow.
I remember this game as having a cuteish cool animal on the cartridge and I tried it out, since I wasn't that good at English I had a hard time understanding what happened in the game but the concept worked for me, I liked it, grew to love it
When I was a kid I loved animals and I loved collecting things (even as simple things as cool rocks) and here I got to combine those two things but to the point, who was my favorite Pokémon to use in battle in my first Pokémon game? The answer is... Hypno!
Well, I never expected that one either when I was young and loved cool and cute things but that was how it turned out.
I met Drowzee at route 11 (I think) and for some reason I liked how it looked and I loved the move "confusion". At this time I didn't have any idea what it'd come to look like but it didn't matter, I wanted confusion.
As it evolved into Hypno there were few things to complain about, it looked cool with it's humanoid shape and hypnotic coin.
I know now that psychic Pokémon were over powered at that time but at that time, he was just AWESOME!
