The Caveman is a bonus costume in Run. He's unlocked from the start and can be worn for Kongregate members. He is extremely likely to be a canon character.
The Caveman looks exactly the same as the Runner, with the only added design being a crude cheetah hide garment, based on the stereotypical caveman design.
- Player_03 was considering them to be added at one point, but he couldn't fit neither of them in the story, or come up with gameplay. To replace the Caveman, the Bunny was created.
- However, Player tried a stomp (immediate landing ability) for him, but it wasn't enough.
