The Stalker was damaged when Humungousaur used a Sumo Slammers attack, which was not recorded into the Stalker, causing it to go haywire. The defeat was followed by Nanomech, who was able to go inside it and ruin the robot's circuits, which caused it to malfunction. It was crushed by Way Big and he dropped it onto Will Harangue's car, destroying it.
