Many fans believe that Red Claw could be a relative of the original Sharptooth, who is the main antagonist of the first film. Some fans even say that Red Claw may be the original sharptooth himself. However, this might be false since the original sharptooth is dead.
Some fans also think that Red Claw is the original Sharptooth's brother.
There is some evidence supporting this claim, as Red Claw and the original sharptooth both have injured eyes. As mentioned above, if Red Claw really is the original Sharptooth, then he may have gotten his namesake feature when Littlefoot and his friends pushed a boulder on him in the first movie.
There is also a theory that Red Claw and his minions separated Chomper and Ruby from their families, similarly to how the original Sharptooth caused Littlefoot to be lonely and orphaned.
Some fans also think that Red Claw may have been the Meanest Sharptooth and some fans think that his scar may have been from falling off a cliff in the 6th film, The Secret of the Saurus Rock.
Red Claw might be the Sharptooth from The Land Before Time VIII: The Big Freeze, who fell off a cliff after being hit by a log which was thrown by Mr. Thicknose which caused him to have an injured eye.
Red Claw has received a merchandise as he appears as a little figurine in a board game called Escape From Red Claw.
On the cover of the board game, Red Claw has a different appearance as he has circular plates on his back which is similar to what the Plated Sharptooth has. On the Red Claw figurine, His scar cannot be seen since he is facing from the opposite side. It is obvious that Red Claw was drawn different for the board game, but he does appear properly as a figurine or a toy.
