In the context of the series lore reflected in the game, the Ultimatrix is a gauntlet-like device that replaced the original Omnitrix after its destruction. Its defining feature is the Evolutionary Function

, which places a species' DNA in a "worst-case scenario" simulation for a million years to create more combat-centric forms. Ben 10 Wiki


The concept of an "unleashed" Ultimatrix taps into a universal power fantasy. The original Omnitrix is about coexistence and understanding alien life. The Ultimatrix, when unleashed, is about survival and dominance. It asks a dark question: What happens to a peaceful species after 10,000 years of total war?

Ultimatrix Unleashed is a functional but forgettable licensed game. Young fans who love Ultimate Alien will enjoy smashing things as Ultimate Humungousaur for a few hours. Anyone else will find shallow combat, repetitive levels, and control frustrations. If you want a good Ben 10 game on DS, seek out Ben 10: Protector of Earth instead — it’s far superior. This one is strictly for completionists or kids who don’t mind repetition as long as the hero says “It’s hero time!” Ben 10: Ultimate Alien — Ultimatrix Unleashed captures

1. Episode Overview

2. Plot Summary The episode begins with Ben using the Ultimatrix to transform into various aliens for a video game commercial, much to Gwen’s annoyance. Meanwhile, the powerful Osmosian villain, Aggregor, attacks the alien hero Ultimos, intending to absorb his powers. Aggregor succeeds and imprisons Ultimos.

Ben, Gwen, and Kevin track Aggregor to his underwater base. During the fight, Ben discovers that the Ultimatrix is malfunctioning—aliens are randomly morphing without his command (e.g., transforming into Humungousaur mid-air, then suddenly switching to Jetray). Aggregor exploits this instability and steals the Ultimatrix core, causing the Omnitrix/Ultimatrix symbol to disappear from Ben’s chest.

Ben must now fight using only the partial energy left in the Ultimatrix, eventually learning to manually trigger the "Ultimate" evolution feature in short bursts to defeat Aggregor’s robots and retrieve the core. The episode ends with Ben reattaching the core and vowing to better control the Ultimatrix.

The Ultimatrix: Features & Instability | Feature | Description | In "Ultimatrix Unleashed" | |---------|-------------|----------------------------| | Alien Selection | Standard transformation into 10,000+ alien forms. | Malfunctioning: random, uncontrolled shifts. | | Ultimate Evolution | Simulates a species’ worst-case scenario combat evolution (e.g., Ultimate Humungousaur). | Ben briefly uses Ultimate forms without full control. | | Core Removal | The central power source can be physically extracted. | Aggregor steals the core, disabling most transformations. | | Voice Command | In later episodes, Ben can voice-activate aliens. | Not yet stable; leads to glitches here. |

Here’s a review of Ben 10 Ultimate Alien: Ultimatrix Unleashed (often referred to as the DS version of the Ultimate Alien game).


Slow but devastating. Humungousaur is for boss fights and crowds. His basic combo slams the ground. Unleashed Humungousaur grows to the top of the DS screen, allowing you to tap sections of the environment to cause meteor showers.

While not part of Ben’s playable arsenal in the game, Ultimate Aggregor is the physical manifestation of the Ultimatrix’s potential for evil. By using the Ultimatrix’s evolutionary function on himself (due to his Osmosian powers), Aggregor becomes a perfect, evolved predator. He represents the "unleashed" nightmare scenario: what happens when evolution has no moral guardian.

A fan favorite becomes a demolition expert. Ultimate Cannonbolt grows metallic spikes on its shell and can control its ricochet trajectory mid-roll. It also gains the ability to emit a massive shockwave upon impact, turning its rolling attack into an area-of-effect explosive event.
