Bully

Bullies are enemies in the Super Mario series, making their debut in Super Mario 64. They can be found in Lethal Lava Land and Bowser in the Fire Sea. Unlike regular enemies, Bullies cannot be defeated by Mario's attacks and must instead be knocked into the lava to be defeated. Big variants of the Bully, named "Big Bullies," appear as a boss in both the first and second mission of Lethal Lava Land. Additionally, an icy version of the Bully called a Chill Bully can be found within Snowman's Land.

Enemy Discoloring
Bullies have been reported to be discolored cyan, purple, and red. Cyan Bullies get their texture from the Chill Bully boss and even can be found in circulated ROM files. Purple Bullies, which can be found in Bowser in the Sky, get their texture from Chuckya s. Red Bullies gradually speed up when running towards the player, and can burn the player when charging unless they have the Metal Cap equipped. They also have black horns and feet.

BackDown
Bullies have an unused animation, referred to internally as "BackDown". It's a simple kick animation, causing the Bully to kick their feet forward when they ram into Mario, instead of appearing to laugh or nod. Some reports claim that this animation is present during normal gameplay in some personalized copies.
