Summary

• Upgrade is visually appealing and can merge with and control technology with diverse abilities.

Ben 10 features a wide variety of aliens that Ben Tennyson can transform into using the Omnitrix, a device that gives him access to numerous heroes with different powers and abilities. As the name implies, there were originally only ten aliens that Ben could become.

However, over the twenty years of the franchise, many more have been introduced. Some aliens have received more screen time than others, with certain ones appearing only a handful of times across the various TV series and movies. This topic ranks the best aliens that Ben can transform into within the franchise. The ranking is based on their impact on pop culture rather than their strength.

Upgrade

The Technological Expert

• First Appearance: Permanent Retirement
• Species: Galvanic Mechamorph
• Select Powers & Abilities: Technological Possession, Shapeshifting, Enhanced Reflexes

The alien Upgrade is often considered one of the most visually appealing in the series, with its striking black and neon green color scheme that distinguishes it from other aliens due to its man-made appearance. This distinction is fitting, as Upgrade is a species created by the Galvan, particularly Azmuth, who also designed the Omnitrix.

Upgrade possesses the unique ability to merge with and control technology. This includes a wide range of devices such as cars, vans, tanks, and computers. It can even enhance advanced technology, allowing Ben to improve machines beyond their original capabilities. For instance, Upgrade can transform the Rustbucket (Ben’s grandfather’s RV) into a battle-ready vehicle equipped with advanced weaponry.

XLR8

Fastest Alien

• First Appearance: And Then There Were 10
• Species: Kineceleran
• Select Powers & Abilities: Tribokinesis, Enhanced Speed, Wall Scaling

XLR8 became a highly valuable alien for Ben throughout the series due to its incredible speed, which Ben would use to pursue fast enemies and vehicles. Offensively, XLR8 is quite effective as well; its lightning-fast reflexes enable quick bursts of attacks using its razor-sharp claws. Additionally, XLR8 can move its limbs quickly enough to create powerful vacuums of air.

In terms of appearance, XLR8 is one of the coolest aliens. Its sleek body design complements its abilities, and the black and teal color scheme fits well within the Ben 10 aesthetic. The built-in visor and the distinctive balls on its feet are also clever features that contribute to how this alien can function realistically at high speeds.

8

Humungousaur

Dinosaur Capable Of Increasing Its Size

• First Appearance: Ben 10 Returns: Part 2
• Species: Vaxasaurian
• Select Powers & Abilities: Enhanced Strength, Size Alteration, Armor Generation

Humongousaur is a powerful alien that Ben frequently used during the Ben 10: Alien Force series. This alien is based on Vaxasaurian DNA, giving Ben immense strength, the ability to grow to great heights, and incredible durability. Its design is relatively simple, resembling a humanoid dinosaur.

However, this design evolved in Ben 10: Ultimate Alien when the Omnitrix was upgraded to allow certain aliens to evolve further. Humongousaur transformed into Ultimate Humongousaur, gaining the ability to shoot missiles and bullets from its wrists, while its tail became a mace, an important enhancement for the alien.

7

Big Chill

A Ghost Bug With Freeze Powers

• First Appearance: Kevin’s Big Score
• Species: Necrofriggian
• Select Powers & Abilities: Cryokinesis, Freeze Rays, Intangibility

The second series in the Ben 10 franchise, titled Ben 10: Alien Force, introduced a completely new set of aliens, many of which were enhanced versions of the original ten. One standout character is Big Chill, who possesses the intangibility and flight capabilities of Ghostfreak but also has the added powers of freezing and wind breath.

Big Chill has an impressive design, especially when he is grounded and his wings fold into a cloak, which is a clever design choice. This alien also featured in the Ultimate Alien storyline, where he gained fire-based powers. The in-universe explanation for this transformation is that Ultimate Big Chill’s ice is so cold that it burns.

6

Spidermonkey

The Term Taken Very Literally

• First Appearance: Be-Knighted
• Species: Arachnachimp
• Select Powers & Abilities: Webbing Generation, Web Swinging, Web Ensnarement

Spidermonkey is a distinctive alien featured in Ben 10: Alien Force. Its design is inspired by the spider monkey, combining monkey-like characteristics with spider powers. Spidermonkey can generate webs and swing from them, reminiscent of Marvel’s Spider-Man, who was a significant influence on this character.

Ultimate Spidermonkey takes the concept in a different direction with an entirely new design based on a gorilla. This version features retractable, sharp spider legs, although future iterations reverted to standard spider legs. Ultimate Spidermonkey is also stronger and more durable, adding bulk to this already agile creature.

5

Cannonbolt

Durable And Strong Alien

• First Appearance: The Big Tick
• Species: Arburian Pelarota
• Select Powers & Abilities: Sphere Transformation, Sharp Claws, Sightless Sensing

Cannonbolt was the first alien introduced to the series after the original ten. It later became part of the original ten alien lineup when Ghostfreak was removed from the Omnitrix, even replacing Ghostfreak in the series’ intro.

Cannonbolt is an alien that can roll up into a ball and propel itself at high speeds, knocking down almost everything in its path. This ability effectively allows Cannonbolt to take down numerous enemies with ease. Ultimate Cannonbolt enhances this concept by featuring a gray color scheme and spikes, which increase its damage output.

4

Diamondhead

A Crystal-Covered Powerhouse

• First Appearance: And Then There Were 10
• Species: Petrosapien Crystalsapien
• Select Powers & Abilities: Crystallokinesis, Crystal Shard Projectiles, Energy Absorption

Diamondhead is one of the original aliens and one of Ben’s best options for defense. Its skin is made of a diamond-like material that is impervious to damage. Additionally, Diamondhead can absorb and redirect various forms of energy, making it virtually indestructible.

On the offensive side, it can create crystals, which can be used as weapons or shields depending on what Ben needs. The crystals can even be crafted into a surfboard, providing a means of transportation. Overall, Diamondhead is certainly one of Ben’s most versatile aliens.

3

Alien X

The Most Powerful Transformation

• First Appearance: X = Ben + 2
• Species: Celestialsapien
• Select Powers & Abilities: Mental Reality Warping, Unlimited Power

When it comes to identifying the most powerful alien in Ben 10, Alien X takes the top spot. This is primarily because Alien X has the ability to change reality, but using this power is not straightforward. Ben, acting as the voice of reason, must engage in debates with Serena, who represents love and compassion, and Bellicus, who embodies rage and aggression, to make decisions, even about simple actions like moving.

Alien X is portrayed as a last resort for Ben, which is why this alien only appears a handful of times throughout the series. Alien X can effortlessly warp reality, time, and space at any level he wishes. Consequently, Ben chooses to avoid using this alien, as its power is simply too immense.

2

Heatblast

The First Shown In The Series

• First Appearance: And Then There Were 10
• Species: Pyronite
• Select Powers & Abilities: Pyrokinesis, Fire Absorption, Fire Cutting

Heatblast holds the distinction of being the first alien that fans encountered in the series, Ben’s very first transformation after he discovered the Omnitrix. His powers are quite straightforward; he can generate and absorb fire and heat, which provides a range of useful applications, particularly when battling villains.

While his design is simple, it is effective, as it captures the essence of an alien made entirely of fire. Heatblast is undoubtedly one of the most iconic aliens in the series, recognized for his versatility in the original show and its subsequent iterations. Additionally, he is capable of standing his ground against a wide variety of enemies.

1

Four Arms

Ben’s Go-To Alien

• First Appearance: Washington B.C.
• Species: Tetramand
• Select Powers & Abilities: Enhanced Strength, Shock Wave Generation, Sonic Clap

Four Arms has become one of Ben’s most frequently used aliens in the series, primarily due to its incredible super strength. Most of the time, when selecting an alien, Ben can simply punch his way through obstacles. In addition to its strength, Four Arms can generate shock waves and sonic claps, and it can jump to impressive heights.

The original design of Four Arms is undoubtedly the most effective, featuring a simple t-shirt design. In later versions, Four Arms took on the appearance of a gladiator and a wrestler, but the original look remains the best. Sometimes, simplicity is key, and having an alien with no significant weaknesses that can tackle any situation with brute force is highly advantageous. As a result, Four Arms is considered one of the most iconic aliens in the franchise.
