Mine would be Pokemon :P or Yu Gi Oh lol.

Sailor Moon was my first. I don’t even know if that can be classified as an anime. I do know it was a long time ago.

My first anime was Dragon ball Z which my older brother showed me and the first episode I was hooked xP this happened when I was 10 xD

I seen sailor moon too and dragon ball, dragon ball z, gundam wing. Man that was back in the day.

Mine would be Tsubasa Chronicle and Bakugan.

Naruto..
I was out of work and started watching Dub eps on Cartoon network at night. After I got back to work I was missing the shows so I started looking them up online. And to my surprise there was over 200 eps :D
So once I caught up on Naruto, I had the anime bug. Since then I have completed over 300 different shows, and I am always looking for my next "fix."

My first Anime was Digimon :3

digimon sailor moon DBZ and Pokemon

Mine was Berusaiyu no Bara("Rose of Versailles" in US I think, and "Lady Oscar" in Sweden. ^^) Starzinger and Sailor Moon. Good times, good times.
