His armour is built out of balloons, construction paper, cardboard and duct tape (copious amounts of it actually). He gathers weapons and defends the weak and attacks the bad guys who want to hurt and maim the good guys. He tries sweet talking the bad guys, but if they persist he will attack. :)
He has fun.
He doesn't hit to hurt, he hits to stop and scare them away. :)
He's a good lad, growing up to be a man who will protect and defend his family in a variety of manners. And it is SO cool to watch him grow. :)
