Hello all, I'm just finished watching the whole anime serie of Trigun and must say it totally rocks. The music used is defenitely one of the best I've ever heard in anime series.
Now let's answer the questions!
1.) Wolfwood. Fantastic, sympathic man. A real anti-hero and I always like such characters better than the main hero (in this case Vash).
2.) Legato. Way more scary than Knives, I'd say.
3.) A friend of mine shared his anime collection with me. Trigun happened to be included.
4.) Never read the manga, so can't say.

1.) Its Vash, he's a joker, but when he's serious, its an entertaining watch
2.) The Nebraska Family.
3.) In all honesty, Hellsing, I just thought they went hand in hand, I seen hellsing first though hehe.
4.) Ive only been able to get the manga....so far.
