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 Harangue's car, destroying it.
Powers and Abilities
The Stalker was durable enough to resist damage from Humungousaur's normal attacks, had 360 degree vision, and was immune to Spidermonkey's webbing.
The Stalker had retractable claws, multiple laser blasters, missile launchers, and a pair of electric antennae.
The Stalker was equipped with countermeasures for every alien Ben had access to prior to Video Games excluding Way Big and Nanomech, including:
- Strong adhesives, which were used to trap Cannonbolt in place.
- A flamethrower, which was used to temporarily blind Humungousaur.
- A non-magnetic alloy, which rendered Lodestar's powers useless.
- Retractable mirrors, which were used to deflect Jetray's neuroshock blasts.
- A built-in heat generator, which was used to melt Big Chill's ice.
- Fire extinguishers, which were used to put out Swampfire's fire attacks.
- A chemical liquid sprayer, which was used to kill Swampfire's plants.
While the Stalker's A.I. was designed to trace and destroy Ben's car, it is not very smart, as it once accidentally attacked a minivan that looked similar to it.
The Stalker cannot counter and can be damaged by attacks that were not recorded into it.
Ben 10: Ultimate Alien
- Video Games (first appearance; destroyed)
- The Stalker does not have counters for Nanomech, Way Big, or Sumo Slammers attacks, since none of these were used when recording all of Ben's moves.
- Visually, the Stalker is somewhat similar to the Omnidroid from the 2004 Pixar film The Incredibles.
- The Stalker has automatic and manual controls.
- The Stalker is a parody of the Spider-Slayers from Spider-Man. The first Spider-Slayer in the comic books was even commissioned and remote-piloted by J. Jonah Jameson, with his face on the screen to taunt the hero.
- The Stalker is a boss on Ultimatrix Unleashed on level 3.
