Hinotama Mario (火の玉 マリオ), translated and also referred to as Fireball Mario (ファイアボールマリオ), is an original transformation that only appears in the Super Mario World story arc in Super Mario-kun. It is a substitute for Fire Mario since, in the first period of the manga, Mario is always capable of throwing fireballs.
The transformation first appears in chapter 5 of the first volume: running away from Porcu-Puffer, Yoshi lays an egg with many Fire Flowers inside. The Fire Flowers latches themselves to Mario and give him a fire aura that he uses to defeat the Porcu-Puffer. Mario then grabs Yoshi and Luigi and leaves the level, passing through a Keyhole, but being still fiery, Mario burns his friends. After they escape, the transformation vanishes.
In chapter 7 of volume 5, to defeat some vines, Mario reaches for the Fire Flower reserve in his pocket, becomes Hinotama Mario, and burns the vines. During the process, he ends up burning Luigi, Yoshi, and himself as well.
Hinotama Mario's last appearance is in two chapters of volume 6. In chapter 7, while traversing Gnarly, the vines attack the trio. Mario is tossed against a ? Block from which a vine, with Fire Flowers instead of leaves, sprouts. Grabbing the Fire Flowers, Mario uses the fire aura to kill the evil vines, burning his tangled friends once again. In chapter 12 of the same volume, while Mario and Bowser are fighting in a Balloon Battle, Mario bursts Bowser's first balloon, which releases multiple Monty Moles. While distracted by the Monty Moles, two of Mario's balloons are popped, so he uses a Fire Flower to gain the fire aura and defeats the Monty Moles. However, in this occasion, Mario calls the transformation "Fire Mario" (ファイアマリオ).
In chapter 6 of volume 7, Carrot passes a Fire Flower to Mario to help him free himself from the octopus's tentacles, burning him with the fire aura. This time, Mario gets burned by his aura, though in a different manner from last time.
