Hothead

Hotheads are large balls of sparking energy that first appear in the game Super Mario World.

Super Mario World
Hotheads first appear in Super Mario World. They slowly move around platforms and can be defeated by Invincible Mario or Caped Mario's Body Press. They are found in #6 Wendy's Castle and Front Door, specifically in rooms with Lil Sparkies.

Super Mario Advance 4: Super Mario Bros. 3
In Super Mario Advance 4: Super Mario Bros. 3, Hotheads are found in the World-e levels A Sky-High Adventure and Puzzling Pipe Maze. Unlike in Super Mario World, they can be defeated by Statue Mario's stomp or by hammers thrown by Hammer Mario.

Super Princess Peach
Hotheads reappear in Super Princess Peach. They behave similarly to how they act in Super Mario World, and are invincible to everything Peach can do. They are found in Shriek Mansion, Fury Volcano, and Bowser's Villa. Unlike most other enemies in the game, they do not have a vibe-based counterpart.

Super Smash Bros. series
Hotheads appear as an item in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U, and Super Smash Bros. Ultimate. Like in Super Mario World, they stick to the stage when thrown and burn anyone that touches it, and also release powerful sparks periodically when moving. It also grows larger if hit with fire and electric attacks, an ability it was never shown to have in the Super Mario franchise. Hotheads move quickly around the platform they are on, but can also just fall off entirely. In Super Smash Bros. Ultimate, a Hothead also appears as a support spirit, equipping the fighter with a Hothead at the start of battle when used.

Hothead's design in Super Smash Bros. Brawl is more realistic-looking, but Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate give it a design closer to that of Super Mario World.
