What is your brother's age? I would not recommend this for a small kid nor for any kid that cannot control themselves. But, if you are looking for anime with tons of battle scenes, try Dragon Ball & Dragon Ball Z.
If you want to control the violence that your brother sees on TV, then consider staying away from Dragon Ball and Dragon Ball Z.
Best thing for you to do, is to watch it first (without your brother around to see it). Then decide a course of action. Good Luck.
