Super Mario Bros. 3
Boom Boom makes his first appearance in Super Mario Bros. 3. Here, he helped Bowser invade the seven worlds found in the Mushroom Kingdom and is the boss in every single fortress in the game guarding the ? Ball that unlocks gates and destroys the fortress so that Mario and Luigi may advance onwards to save Princess Peach.
When he is battled, he walks back and forth all the time, trying to attack Mario or Luigi. The two bros. must avoid it and jump on his head, making him temporarily reveal his spikes. Then, he either charges quicker back and forth or uses his wings to fly, depending on the location where he is fought. The more times jumped on, the more Boom Boom's aggressiveness raises. He must be jumped on three times to be defeated or have fireballs or hammers thrown at him five times total.
There is also a gray version of Boom Boom found in Desert Hills as a boss.
Super Mario 3D Land
Boom Boom reappears in Super Mario 3D Land and has had some changes in appearance. He is bigger than last time with him being about a forehead bigger than Mario and Luigi. He has a red shell lacking spikes now and has some new attacks. He now spins around continuously until being dizzy, giving Mario a chance to attack him. When he is jumped on, he spins around crazily in his shell which Mario must avoid. He must be jumped on three times, like last time to be defeated. He now releases many coins instead of a ? Ball when defeated.
He is known to be in the airship level World 2-5. He is in Worlds 3 and 7 too. A female character very similar to him named Pom Pom also appears in this game as well. She is another boss in the game, and in World 7, she is fought alongside Boom Boom. In latter fights, he will also leave a trail of fire behind as he tries to spin into you.
