Worf

Worf was created when Meta Knight died and had to be revived by being hit in the face repeatedly by Luigi with a magic hammer. Due to Inexplainable Quantun Physics Equations, Meta Knight somehow split into three different people: Meta Knight, Roogles, and Worf. Roogles immediately died after coming to life because MK got hungry. Worf somehow managed to escape being eaten by jumping out of MK's right nostril right after being swallowed. After this incident, Meta Knight's self esteem was so deflated that he ran himself over with Wario's motorcycle. In the process, his nose fell off. This is why MK no longer has any nose. Or any eyebrows, either. Meta Knight's nose later reappeared in the episode Bowser Finds a Nose.

Worf's later years were spent in and out of prison because he had a strange habit of turning into a hot air baloon whenever he sees anything green.
