If the enemy he is targeting either dies or leaves his line of sight, he will change targets to the enemy closest to him.
Once he stops running, he will remain stationary and act as a turret, shooting whichever target (enemy or built object) is closest to him within line of sight. He counts as a charging target while running, meaning if he runs into another charging Bob, a Charge, Rocket Punch, or Shield Bash, he will be knocked down and will knock down the user of the ability without dealing damage. If he bumps into an enemy (or enemies), he flings them into the air dealing 120 damage to them. He will then run forward until he hits an enemy, a built object, a part of the environment, or travels 70 meters. Bob slams onto the ground 5 meters in front of Ashe.
