megaman is a game intended for kids...
Actually, Capcom stated that while Classic was aimed towards kids, the X series were aimed towards a more mature audience. And Rockman Zero had tons of blood in it, not to mention X4's cutscenes.
Plus, MEGA Man may be for kids, but ROCKman is totally not aimed for them. Remember Legends had extreme censorship of some things (I.E: Ero book, Paprika kicking). Zero had quite an amount of blood coming out of the Resistance Soldiers in the intro, too, though the amount of blood was reduced in MMZ. X, as I said, had also quite an amount of blood in the X4 flashback. The X and Zero series had quite a dark storyline, CLEARLY not for kids (Inb4 Elf Wars killing most of humanity).
