My first level 100 was, of course, Pikachu. Even today I still level a Pikachu to 100. Heck even recently it saved me. A battle against one of my friends came down to the last move. Just whoever got in a hit first. My Pikachu was in the yellow and his Dragonite was in the very low red. I luckily outsped him using Quick Attack. I found out he tried using Extremespeed. So if I didn't quick attack, then I would've lost. Still my Pikachu has saved me multiple times.
