If I'm gonna pick my favorite, it has to go back to my childhood. The first anime I watched religiously was Speed Racer. I don't know what it was about it but my brother and I were so into it. We were lucky to have a channel that showed old syndicated programs. My second favorite would be Battle of the Planets or better known as Gatchaman (or Science Ninja Team Gatchaman). Then my third is one I didn't get to see too often but liked it anyways, Mazinger Z.
