Segmentasapien

Segmentasapiens are a species from the planet Polyominus.

Anatomy
Segmentasapiens' appearance is similar to a gorilla made out of building blocks that come in three main colors (which varies between universe) with black lines all over their bodies with large fists and curved feet.

Whenever they walk, either they bring their feet up and put it in front of them on the ground or walk with their arms in front and legs in the back almost like a human.

Powers/Abilities
Segmentasapiens have enhanced strength and shapeshifting powers that allow them to transform into multiple things, such as a wall, catapult, cage, etc.

If a Segmentasapien's body is damaged, they can easily reform the broken pieces, allowing them to survive explosions and being bisected.

Segmentasapiens can turn their arms into guns (dubbed "Bloxx-lobbers") and fire explosive blocks that are painful to step on.

Segmentasapiens are shown to be immune to high amounts of radiation, such as when reentering a planet's atmosphere.

Weaknesses
While Segmentasapiens are highly durable, they can still feel pain from being beaten down by an Evolved Vaxasaurian. Similarly, plummeting through Earth's atmosphere can make them feel like "[their] butt is on fire".

Segmentasapiens are vulnerable to acidic substances, such as the saliva of a Skreegit and hydrogen chloride gases generated by Gutrot's Species.

Ectonurites and other beings capable of becoming intangible can easily phase through a Segmentasapien if they are trapped in its dome form.

Segmentasapiens can be lifted and thrown by a species with as much strength as a Thep Khufan. Similarly, they can be easily overpowered by a Galilean's gravity powers.

Like other organic beings, Segmentasapiens can be erased from existence by a Chronosapien Time Bomb.

Although it has not been determined yet, there is probably a limit to how big a Segmentasapien can become.

History
Segmentasapiens are one of the oldest lifeforms in the universe and are able to rearrange their matter at the sub-atomic level to create a vast variety of shapes and forms. They evolved this way in response to invasions of their homeworld Polyominus by warring alien species.

To avoid detection by so many violent interlopers, Segmentasapiens began to transform themselves into the very architecture of their planet. In this way, they could remain hidden in plain sight as army after army over the centuries marched through or even occupied their eerily abandoned, medieval-style walled cities, finding not a single living creature—because the living creatures are the cities. Segmentasapiens are in fact so rarely seen in their true form that many consider them to be only a myth.

Omnitrix Transformation
The Omnitrix's Segmentasapien representative is named Bloxx, who first appeared in the Omniverse episode "The More Things Change: Part 1". Bloxx solely appears in Omniverse.

The Ben Tennyson of Dimension 23 has an equivalent of Bloxx named Build-A-Guy, who first appeared in the Omniverse episode "And Then There Were None".

Bloxx is available in Mad Ben's Omnitrix, as glimpsed in the Omniverse episode "It's a Mad, Mad, Mad Ben World: Part 2". According to Derrick J. Wyatt, Benzarro has Bloxx available in his Omnitrix.

Etymology
Segmentasapien is a combination of segment, which is a reference of their ability to create different objects in segments, and sapien.
