Bloxx is the Omnitrix's DNA sample of a Segmentasapien from the planet Polyominus.
Bloxx's 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 doesn't have a primary color and has white eyes with a black face.
Bloxx wears the Omnitrix symbol on his head.
Powers and Abilities
Bloxx's shapeshifting powers allow him to transform into multiple things, such as a wall, catapult, cage, etc. If Bloxx's body is damaged/broken he can easily reform the broken pieces immediately. He can form more blocks on his body, either to grow in size, create constructs of blocks, change himself into a larger construct, or even use them as projectiles.
Bloxx can willingly detach parts of his body to get out of certain situations and turn his hands into guns, dubbed the Bloxx-Lobber, and fire explosive blocks from them. 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 is very dense and durable and has enhanced strength, as he was able to punch into a Dimension 12 robot and shut it down.
Bloxx is shown to be immune to extremely high amounts of radiation, as shown when he protected Rook from dying in the 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 being beaten down by Negative Ultimate Humungousaur. Similarly, plummeting through Earth's atmosphere caused him great discomfort, enough to make his butt feel like it was "on fire".
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.
There is probably a limit to how big Bloxx can become, but it has not been established.
