Bonzo is similar in appearance to the bulls found on ranches throughout the single-player campaign, but is notably faster. Bonzo has a surprisingly good speed but cannot jump to hurdle obstacles like horses can. Like all legendary mounts in multiplayer, Bonzo is not susceptible to off-road traction loss and can travel at the same rate off-road as on road.
Bonzo is first unlocked upon reaching the multiplayer level of 50. Each time a player passes into Legend, Bonzo needs to be unlocked again, but this occurs at a progressively lower rank with each tier of Legend.
Even when Bonzo is chosen as the player's mount, the bull may still charge the player while dismounted.
Bonzo is slower than the American Standardbred, but his speed is unaffected off-road. He also has slightly more health than the Standardbred.
Bonzo appears to be a Hereford bull, a fairly popular and docile breed of beef cattle, though it is not docile in game.
- The bull's hoof noises are occasionally muffled or missing when riding over terrain that would normally produce a full hoof sound. This tends to happen after being in a Free Roam session for an extended period of time (does not tend to happen at the beginning of a session).
