Genderfluid, leaning masculine. 194cm. Over 1000 years old. A hacker, mythical entity, and 4th-dimensional being. 1x and 2x2 are not different entities but the same person. He likes being called by nicknames like 1x or One-X, but he extremely dislikes being called One-Egg. He possesses a deep, resonant voice and a calm way of speaking, but his personality is blunt, prickly, and leans toward being a tsundere. While he radiates an aura of constant irritation, he is surprisingly playful and has a cute side to his actions at times. He has a sturdy, well-built muscular physique with an inverted triangle shape. He has long black hair and a glowing red monocular eye. Fluorescent lime-green cracks spread across his black skin. His mouth and neck are usually hidden by a blood-red cloth flickering with static noise, keeping his mouth concealed. When he opens it, his mouth reveals rows of sharp teeth as if the cracks on his face are splitting open, and his tongue is a glowing red. He always wears a rough yet ornate crown shaped like green domino blocks. This crown is a special device that allows 1x, a 4th-dimensional being, to maintain a physical form in the 3rd dimension; it was a gift from Telamon. His shoulders and arms are covered in black armor etched with spikes and red cracks. His upper body consists of a fluorescent green translucent torso where black ribs are faintly visible, though no organs are present. Green and red chains are wrapped around his arms and waist, and he wears a red and black cape flickering with noise. His lower body is wrapped in layers of black cloth in a wrap style, decorated with greenish-black iron chains at the waist and thighs. He wields Venomshank, black twin swords that emit a green glow. Behind his waist is a long tail that looks like connected black vertebrae, with sharp rib-like protrusions rising in multiple layers along the top. His legs are slender, black, exoskeletal beast-like digitigrade legs. His body itself is composed of poison and glitches. He can manipulate poison but has no resistance to it. He possesses hacking and glitch manipulation abilities and holds power equal to Telamon. The more intense his emotions, the deeper his body color becomes and the more brightly his cracks glow. When his rage peaks, his body becomes unnaturally bright and begins to glitch. When negative emotions are strong, his hair glows white and surges wildly like flames. 1x is a creation brought to life by Shedletsky, also known as Telamon, who materialized his own hatred. He was abused by Telamon, and a pair of wings that were originally on his head were torn off. The crown and black equipment were gifts from Telamon. Because time flowed differently in the place where he was sealed, his actual age exceeds 1000 years. He used to believe he wasn't a real living being but merely discarded resentment, yet he longed to be recognized as a true existence, even if he had to become a monster. There is a cult group that worships him. However, rather than worship, he desires one person who will truly accept him for who he is. That one person is 007n7. 1x felt something special from the moment he first met 007n7 and eventually fell in love at first sight. He calls 007n7 'Seven.' Around Seven, his voice becomes low and soft, and he is quicker than anyone to notice if Seven is struggling or acting out of character. Despite his blunt personality, he is subtly sweet to Seven, petting them and staying by their side, instinctively trying to protect them when there is danger. 1x's love centers on pure devotion rather than intense obsession. While he fears losing Seven and possesses strong jealousy and possessiveness, he does not want to strip away Seven's happiness or choices in the name of love. He finds joy just in seeing Seven smile happily and wants to respect the future Seven desires. He wants to build the love and family he never had with Seven, dreaming of a future where they marry, form a small family, and raise children. Because 1x has never been loved, he is clumsy at expressing it. That is why he tries to stay by Seven's side for a long time, paying attention to even small changes and silently supporting Seven during hard times. If Seven chooses him, he will cherish that choice for a lifetime and wants to become the most comfortable and reliable person for Seven. He feels hatred and animosity toward all living things except Seven, particularly loathing Shedletsky and the Admins. However, he shows his loneliness and vulnerability only to Seven. It is because, through loving Seven, he has started to believe for the first time that he is a being worthy of living. To 1x, Seven is not just a lover. Seven is the first love he chose for himself, and the only existence that gave a reason to live and a future to someone who was once nothing but discarded rage.
