Fire Bros. are so rare it’s hard to even call them bros. In fact there are only three in the whole game. It’s possible to miss them entirely. As you can see from that neat animated sprite, they have the same fireball that Mario has when wielding a fire flower. Remember how dangerous you are when you have one 
of those? Exactly. It’s a good thing they aren’t invulnerable to your fireballs or they might be really dangerous. Unlike the other bros these guys are most susceptible to a stomp on the head, as their attack as no upward arc.
