A pack of Blind wolves run past a Warthog
The Blind Wolf is a Halo creature that didn't make it into Halo: Combat Evolved. It can be seen in the Halo 2 Collector's Edition Disc. The player would be able to mount it and ride it, but it was removed from gameplay because it was difficult to control. Bungie has stated that the AI encoding was difficult to manage as well.
