Gotta be Pokemon of course I didn't know that it was anime back then. As for the first, I know this is anime type memory I had, it was probably snippets of Inuyasha that used to air back on Adult Swim since I never really had an interest in DBZ. I always found ED2 really enchanting even back then. As for the first series to get me into anime proper, that was FMA:B and that didn't happen until high school.
