Broozer

Broozer appeared in 2006 video game called New Super Mario Bros.. Broozers are boxing ghosts that first appear in New Super Mario Bros. "Broozer" is derived from the words "bruiser" and "Boo". They are humanoids wearing a grey sheet over their body, brown shoes, and deep-red boxing gloves. In New Super Mario Bros., they have angry yellow-orange eyes with Boo-like smiles containing sharp teeth, but in every later appearance, the eyes are sunken with a green hue, and the smiles become angry scowls, bearing much larger teeth. They make sharp hissing noises as they attack - either made by them or the tailwind of their punches.
