For me.. it's Pokemon (Sailor Moon was long forgotten lmao ;; ), then Digimon (which stayed longer than my Pokemon phase), and sitting alongside it is Cardcaptors. That's what started my enlightenment on how cruddy it really is.. but that's besides the point. My further exposure to Japanese vocalized anime is Di Gi Charat and Pita Ten LOL.

Code Geass definitely left a landmark of anime I'll remember. XD
