(He's currently in the middle of a redesign, so he's in pieces right now and I don't have a high-quality picture on hand; instead, I just have this drawing)
Zurakia was a Great Being who was obsessed with war. He despised his brothers for "wasting" their resources on a useless, continent-sized robot, instead imploring them to focus on more pragmatic endeavors.
This frustration led him to form a coup against his brothers- unbeknownst to him, his own creation turned on him, mortally wounding him and seemingly dead. Alone in the barren wasteland of Spherus Magna, he slowly rebuilt himself, becoming more powerful than any of his brothers could have imagined.
Zurakia has abandoned his original body, creating a new one identical to the first in all but one way: this new body is made out of hundreds of thousands of tiny, microscopic cubes that can fuse together into a singular mass or act and move independently. These have the power of flight and can store a gargantuan amount of energy- combining into a practically limitless reservoir which each cube can release individually or coalesce and fire in a large blast from his palms. This energy can also be used to recreate cubes that may be destroyed in battle.
Zurakia, through his studies, has developed an ethereal substance known as "Zurakian Energy" (often referred to as ZE). This substance allows him to completely control energy that comes into contact with ZE, which he can spread around him like a large, invidible cloud of influence. This means heat, kinetic, electrical, chemical, and even pure energy are completely under his control and can easily manipulate and turn enemy's attacks back on themselves.
This ZE is strong enough that it can even cling to Zurakia in an aura, taking hold of the energy that makes up his atoms and acting as a shield. This aura negates any non-physical stimuli that Zurakia endures. This means many mask, kraata, rhotuka, or other miscellaneous powers are completely useless unless their effect is entirely physical.
This technology is also used in his large, metal arm. This absorbs any retaliatory, opposite energy used to resist blows and simply adds it to its own outgoing force- essentially causing a chain reaction that causes anything that blocks his punch, instead, go towards making his punch stronger and stronger until it can no longer protect the target.
