Squirtle, my first Pokemon. Everybody remembers their first Pokemon right?
Snorlax, my first level 100, the one that I use for my username, the one and only mighty Snorlax, my favourite Pokemon.
Dodrio, the other memorable level 100, my first for my Gold game, where I probably clocked the most hours on, basicly where I spent most of my time talking to NPCs and other shenanigans. GOD I LOVE POKEMON G/S/C.
Feraligatr, my starter in my favourite game, Pokemon Gold. Regularly Ice Punch the crap out of Lance's Pokemon in my countless of runs in the Elite 4.
