In 1997, Avenger was created with a hot rod in mind, and S-10 body. There was only one person capable of handling its violent nature - Jim Koehler. The body was updated in 2002 to become a '57 Bel Air. As part of "Team Scream", Jim and Avenger have been to every Monster Jam World Finals. Jim acknowledges the fans in helping him make it to the Monster Jam World Finals because Avenger was often voted “Fan Favorite.” Avenger has two Monster Jam World Finals Freestyle Championship (2003, 2011).
