My first anime were Shin Chan, Samurai King, Pokémon, Digimon, and Dragonball Z. I watched dragonball Z with my brother when I was like, 5, I think. We watched it in Japanese sometimes for fun, and we laughed because it sounded funny
The first manga is Dragonball, since we had a Dutch version of it at home, around five volumes. (don't know how we even got those)

And the first anime I watched online, from start to end, was D.N.Angel. And it got me hooked on anime instantly. (even though it was shoujo..)
