So what exactly makes "battle shonen" a distinct genre instead of just being lumped in with the martial arts genre? Adding magic or superpowers to the mix doesn't change the fact that it's martial arts.

I’d say it’s the other way around where “martial arts” is a subgenre defined by influence from chanbara, kung fu movies, etc. Dojos, xth generation head of the y school, emphasis on “technique,” interschool duels, tournaments.
I was thinking about how Fist of the North Star exactly fits that “stoic master wanders around slaughtering every bandit and dark master in sight” genre and then I realized, Trigun is the same way too, as appropriate for the syncretism in Westerns. Vash is a master of the school of the gun.
