The Stalker was a robot commissioned by Will Harangue in which he recorded Ben's aliens' moves in a video game motion capture-type scanning.


The Stalker's only appearance was in the episode Video Games, as part of Will Harangue's plot to "destroy Ben Tennyson". It recorded all but two of Ben's aliens: Way Big (being too big) and Nanomech (being too small).

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 possesses immense strength, allowing to easily overpower aliens like Humungousaur and Lodestar, as well as break Gwen's mana. It is also durable enough to resist damage from Humungousaur's normal attacks.

The Stalker has 360 degree vision and retractable claws.

The Stalker is equipped with multiple laser blasters, electric antennae and numerous missile launchers. It can shoot strong adhesives to keep Cannonbolt in place.

The Stalker has a flamethrower to temporarily blind Humungousaur.

The Stalker cannot be magnetized, rendering Lodestar's powers useless.

The Stalker has retractable mirrors to deflect Jetray's neuroshock blasts.

Spidermonkey's webs are useless against it.

The Stalker can create enough heat to melt Big Chill's ice.

The Stalker has built-in fire extinguishers to put out Swampfire's fire attacks and can spray a chemical liquid that can kill his plants.

The Stalker likely had countermeasures for all of Ben's other aliens (except for Way Big and Nanomech) as well, although these are never shown.


While the Stalker's A.I. was designed to trace and destroy Ben's car, it's 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.

The Stalker with a monitor screen

  • 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.
