Solar comes from a tribe of lucario well known for raising their young to be strong fighters, honorable warriors, and aware survivors. The mentality of the tribe is to do what is best for the tribe, and everyone contributes in various aspects. Males are typically trained in hunting, survival, and advanced combat. Solar was chosen by a mercenary group to join their team and received further training in tactical situations. As a result of all this training, Solar tends to be a quiet observer of his surroundings and potential threats than actively conversing with others. His ability to see aura gives him a very strong moral compass, and makes it difficult to attack others whose aura shines as good.

By a few minutes, Solar is the older brother of Lunar. Being the first born during a solar eclipse, it was only fitting he be named Solar. He belongs to the Osponje (Oz-pon-hey) tribe, which is a lucario clan renowned for their strength, organization, and strict training regimens. As a male, Solar was trained daily in hand to hand combat and aura. During training, it was discovered his aura abilities were disadvantaged yet he had other abilities instead. His training regimen was then adjusted to hone these capabilities. Almost a year after he evolved into a lucario, Solar was selected to join the Mamuno Mercenaries. As a mercenary, he received further training in the arts of stealth and alternative combat. His arsenal includes smoke bombs, flashbangs, and minor explosives all made of aura that is detonated at his will. Since he can see the true aura of creatures, he is incapable of killing anyone who does not possess an aura of true evil. Solar's story has a critical time point, resulting in 2 stories that take place in different dimensions. By default, the Posmastar Dimension is the story used for Solar.

Posmastar Dimension

After years away as a mercenary, he made a visit to his tribe and found his sister had evolved while he was gone. However, an enemy followed him and attacked Lunar, stabbing her several times. Sensing a problem, Solar quickly ran to his sister’s aid. Blinded by anger, he immediately tracked down and killed the attacker. Snapping out of it, he returned to her and realized he never bothered to help her. Stricken with immense remorse, his mind was unable to handle the emotional turmoil and blacked out. Hours later he awoke back at the tribe. The other members explained there was an explosion and they found him, Lunar's body, and the charred remains of the attacker. Emotionally unstable, he discontinued work as a mercenary and became a wanderer. Years later, it was discovered he had used Net R in his rage and absorbed Lunar's fading aura on accident. Her aura now resided within his body. When moonlight shines upon him, his body morphs into Lunar's and her personality comes out. For all purposes, he truly becomes Lunar and does not usually recall what happens while Lunar is the dominant aura. Solar does not return until contact with sunlight is made. A method to split them apart was discovered, but it is not permanent as their auras are still bound together. If the opposite light shines on either of them, they merge back together. Moon Stones and Sun Stones have been found to cause or deter morphing. Solar is continuously haunted by what has transpired and, despite her being alive within him, he still blames himself for her death. He is determined to find a way to get her back into a body of her own. Equinox is an anomaly that eventually came into existence as a result of when both sunlight and moonlight were present. Equinox's demented nature further plagues Solar's troubled mind.

Other Dimensions

Outside the Posmastar dimension, when Lunar was attacked and Solar came to her aid, he instead sought out medical help which resulted in her surviving the attack. This allowed Solar to remain mentally stable and continue his career as a mercenary. For years, he was obsessed with finding everyone associated with her attack, killing them in order to send a clear message to the one he was after. It was discovered that he was somehow eradicating his prey's aura in its entirety, leaving nothing more than a soulless husk of a body. His message was received loud and clear, resulting in no one ever daring consider the thought of attacking Lunar again. Unfortunately, as he progressed, he was starting to become crueler and more evil himself. Lunar sensed this change in him during a visit and pleaded with him to stop. He reluctantly left the mercenaries and exiled himself from the tribe for what he had done, feeling that he had crossed a line and brought shame to the tribe. Now he wanders about on his own, occasionally taking up jobs for hire on his own so he has money to get by. Equinox does not exist in this reality.

Solar is straight with no interest in males. The Osponje Tribe has “mating rituals” that he occasionally abides by. Normally, dominance is determined through a playful form of combat. Solar has come to terms that if the partner is submissive, then this ritual is unnecessary as dominance has already been decided. In the event a female attempts to show a form of dominance over him, they might be in for a surprise if his mind decides to abide by tradition. Sometimes he will seek companionship to satisfy his urges, but generally his reclusive nature causes him to keep to himself, requiring others to approach him.
