Bloxx is the Omnitrix's DNA sample of a Segmentasapien from the planet Polyominus.


Being an organosillicon-based life form with segmented hardened quasi-organic polymer skin, Bloxx's body is made up of individual blocks that he can rearrange at will. His appearance looks similar to that of a gorilla made out of building blocks. He has three main colors, which are red, blue and yellow, with black lines all over his body. He is mostly red and yellow with some spots of blue. His feet are stubs and his hands are extremely large, balancing most of his body. He has studs all over his body.

Bloxx wears the Omnitrix symbol on his chest.

Powers and Abilities

Bloxx's shapeshifting powers allow him to transform into multiple things, such as a wall, catapult, and cage. If Bloxx's body is damaged or broken, he can easily reform the broken pieces immediately.

Bloxx can generate and form more blocks on his body at will, either to grow in size, create constructs of blocks, or change himself into a larger construct.

Bloxx can willingly detach parts of his body to get out of certain situations.

Bloxx can turn his hands into guns, dubbed the Bloxx-Lobber, and fire explosive blocks from them as projectiles. The blocks are also painful to step on, as seen when Humungousaur used them to pain Khyber as Tyrannopede into releasing him from his mouth.

Bloxx has enhanced strength, able to punch into a Dimension 12 robot and shut it down, pull rocks straight out of the ground, and carry Fistrick. He is also very dense and durable, being able to survive being shot multiple times, beaten down by Negative Ultimate Humungousaur, and crushed by Ma Vreedle.

Bloxx can jump exceptionally high, as he was able to leap up to a high platform where Ma Vreedle was.

Similar to Cannonbolt, Bloxx can encase people or objects inside his body, as shown when he protected Rook from dying in the Earth's atmosphere.

Because he is made of building blocks, Bloxx can survive in the vacuum of space. He is also immune to extremely high amounts of heat and radiation, as seen when falling through Earth's atmosphere.


Despite his shape-changing abilities, Bloxx can be broken when hit with enough force, but can easily rebuild himself right after.

Beings that can become intangible, such as Ectonurites, can easily phase through Bloxx if he traps them in his dome form.

While Bloxx is highly durable to an extent, he still feels pain, as seen when he was acting as a railway bridge to save a train. Similarly, plummeting through Earth's atmosphere caused him great discomfort, enough to make his butt feel like it was "on fire".

Bloxx's strength has a limit, as he was unable to punch through a force field surrounding a bomb.

Bloxx is vulnerable to acidic substances, whether it be liquid or gaseous.

Like any other organic being, Bloxx is vulnerable to being erased from existence by a Chronosapien Time Bomb.


Bloxx first appeared in "The More Things Change: Part 1", where he saved Mr. Baumann's shop from being destroyed with Rook's help.

In A Jolt from the Past, Bloxx fought Fistrick and his gang.

In O Mother, Where Art Thou?, Bloxx was defeated by Ma Vreedle.

In For a Few Brains More, Bloxx took Azmuth's brain from Ultimate Albedo and was defeated by Negative Ultimate Humungousaur.

In Rook Tales, Bloxx was defeated by Kundo.

In Breakpoint, Bloxx saved Rook from being burnt to death in the Earth's atmosphere before he reverted.

In It's a Mad, Mad, Mad Ben World: Part 2, Bloxx and Handy Man gave water to the enslaved Benwood citizens.

In Stuck on You, Skurd gave Humungousaur the Bloxx-Lobber to fight Khyber as Tyrannopede.

In Let's Do the Time War Again, Skurd gave Gravattack the Bloxx-Lobber to catch the Time Beast.

In Third Time's a Charm, Skurd gave Shocksquatch the Bloxx-Lobber to battle Charmcaster.

In Malgax Attacks, Skurd gave Whampire a pair of Bloxx-Lobbers to fight Malgax.

In A New Dawn, Bloxx appeared for a short time when Ben was cycling through his aliens.
