My first will always be my favorite:

Science Ninja Team Gatchaman! 

I knew it as  Battle of the Planets

Does YuGiOh Abridged count?

If not, then Yu-Gi-Oh (the first three seasons), Pokemon (until it began to suck) and DRAGONBALL Z!

OP I loved all the animes you listed as a kid, but right now I like One Piece, think it's the best anime I have ever seen.

Death Note all the way..

Rurouni Kenshin, Yu yu Hakusho, Hajime no Ippo, Fullmetal alchemist(both series) and I think Hunter x Hunter.

My others(which I think were great but in other form) are Slam Dunk, Dragon ball(and Z), Captain Tsubasa and Saint Seiya.

I knew it as G Force(or Fuerza G here), I didnt watch it so much because at the time it aired here I was little

I discovered that show around the time hip hop dropped

I like Bleach, Samurai champloo, Samurai 7, Monster, FMA, Naruto, Death Note, Cowboy Bebop, Gintama, Ghost in a Shell and many more.

One Piece

lol I remember when I saw it it wasnt even the first time it aired, some times in national television in my country they put old shows and thats the time when I saw it, something in the mid 90s, it was pretty cool.
