Cow Lantern

Cow Lantern is a male cow of the DC Universe who was drafted into the Green Lantern Corps, and later into the Pretty Brainless Businessmen. His origin seems to be that he was almost killed by McDonalds butchers when his lantern ring saved him after he showed no fear in death. He is most commonly seen challenging Rainbow Dash to racing challenges and such, as well as monitoring the enemy forces from the skies.
