Wally West is the teenage nephew of Blaze Allen. They both work at a circus. After his wife's death, his Uncle Blaze began acting strangely. Wally soon found out why and discovered that his uncle was the Speed Demon.
When his uncle was in trouble, Wally was approached by Merlin. Wally agreed to his help and got a demon of his own. Unlike Speed Demon, Wally uses a flaming motorcycle, much like the original Ghost Rider.
The question remains, if Speed Demon is bonded with Etrigan, which demon is bonded to Wally?
