Devil King Gaelion

"I am... inevitable."

- Devil King Gaelion

Devil King Gaelion (悪魔王ガエリオン, Akuma-ō Gaerion) is a demonic entity that resided within Kamijou Touma's right hand, sealed by Imagine Breaker. While serving as a hidden figure throughout the Toaru Michi no Imagine Breaker Storyline since the earliest days, he becomes the main antagonist of Toaru Tamokuteki no Imagine Breaker, where he declares war on the Multiverse, in his quest to return everything to zero. His mission involves amassing enough power so that he can even erase the Gods and Outer Gods into a state of Nonexistence, by draining energy from powerful beings, and fusing with his generals, Mare, Michealis, Satella and Sebas.

Appearance
After Gaelion took over Touma's body, it began to change and alter to a form befitting Gaelion. With this, he has long ashy-white hair, red eyes that occasionally become dark at times, tan skin, and a build of that of a man in his prime, age wise and physical condition wise. He wears red and white ceromonial robes, though at times, he is seen bare chested.

In his ascended demon form, his hair grows even longer, becomes a flashy gold color, and his eyes become gold as well. In this state, he becomes completely nude, though parts of his body is in a state of nonexistence, which can be manipulated to form limbs, weapons, and other things as he wishes.

Personality & Character
Before Gaelion was freed and took over the body of Toma, he was cited as a vengeful creature that was filled with endless rage and malice towards life itself, and especially the Gods who sealed it away in Imagine Breaker. He had a burning desire to completely eradicate everything in sight, and this was shown during his official debut, when he started attacking everything indiscriminately. Before this however, he was shown to be manipulative, attempting to send Touma into despair early on in the series so that he would be ore susceptible to takeover when the seal was broken.

Sometime after taking over his body, Gaelion became connected with Touma's soul, sharing emotions, views and beliefs with one another. The Architect likens this to a phenomena similar to a fusion, only that Touma has completely relinquished control to Gaelion in his despair. This results in Gaelion taking on a more calmer and methodical personality, where he develops Touma's empathic nature and wishes to help those in need. He comes to realize that all of existence is a painful hell for everyone and that in order to save everyone, he must completely erase them from existence.

Gaelion was aware that simply killing everyone was not enough, as he knew that existence continued, even after death, so he had created several nonexistence entities to obey his new directive, of gathering enough power to return everything to zero (Nonexistence).
