Survivors from the original Battletoads, they're back to even the score. Tweak their beaks with a well placed punch and watch these feathered fiends fall. - Official description from the manual

The Raven is an enemy type in Battletoads & Double Dragon: The Ultimate Team. Originally from Battletoads, they appear during certain portions of Stage 3 in which the player must rappel through certain chasms and fight them. Like in the game where they originated, the player can use the beaks of dead ravens to attack other ravens.
