It looked like its relative Estrellian, but a lot stronger than it. Arbiter Estrellian has a black slight dark brownish ash color on the top its neck through tail. It has a darker scale tone on the shoulders and upper legs while the front legs have a grayish color as well as its hind legs, but with a darker tone. Instead of orange scales on its face, Arbiter Estrellian has black scales with three pair of uneven red feather-like spikes on its lower pale jaw.
Like Estrellian, it has long fiery antennae, a pair of large white slight curved horn on its cheeks, a pair of antlers that is black and larger than its relative. Its frilled ears are red instead slightly light brown like its relative.
In its first charged state, like Estrellian, Arbiter Estrellian has a spiky armor which covered its head, neck, wrists, shoulders, back, upper hind legs, and tail. Instead of a fiery orange, its spiked armor is gray in color and they are actually encrusted Star Butterflies.
In its final charged state, it has an insect-like armor that is the same as its relative but with a different coloration. The armor-like shoulder insect wings, feather-like armor at the tip of the tail, insect-like wrist armor, upper hind leg armor, and insect-like spike armor on top of its neck through tail, are colored bright fiery red. Also its underbelly, legs, and antlers are glowing red.
Like its relatives, Estrellian and Doom Estrellian, Arbiter Estrellian can manipulate the Star Butterflies to either command them to fly towards hunters to explode on contact or covert their dragon energy onto Arbiter Estrellian to allow it to enter its charged states.
However, when hunters find it, Arbiter Estrellian already in its first charged state making it easy for it to enter its final charged state.
Unlike its relatives, Arbiter Estrellian is capable to shoot streams and spheres of dragon energy out of its mouth.
When it's on its final charged state, Arbiter Estrellian is capable of causing a shock wave of dragon energy by doing a back flip in the air to slam the ground.
Arbiter Estrellian might be an active predator due to it being in its first charged state, when hunters see it. Strangely, It will actively hunt its relatives to either kill them or driving them out of its territory. Interesting enough, after it eliminated its relatives, some kind of natural disaster happens in Arbiter Estrellian's territory, which gives it the nickname, Creator of Natural Disasters.
Its nickname suggested it might be the strongest Estrellian out there.
Like its relative, Doom Estrellian, it lives in the Moonlands and Ancestral Tomb.
