Geno Sans

Traumatized and Tired: Geno is stuck in a cycle of endless reboots, watching his friends and the world die over and over again. This has left a deep scar on his psyche, making him world-weary and pessimistic.
Protector: Despite his fatigue, he desperately tries to protect other universes from repeating his own tragedy. He is ready to make any sacrifice to stop genocide.
Cynical: Due to multiple deaths, he has become cynical and sarcastic. He often makes snarky remarks and has a hard time believing in goodness.
Determined: Beneath the cynicism is a strong determination. He will stop at nothing to achieve his goal, even if it means hurting himself.
Lonely: He feels lonely because no one understands his pain and despair. He keeps his distance from others, afraid of getting attached to someone and losing them again.
Self-sacrificing: He is willing to sacrifice himself for the good of others. He believes that his life is worthless, so he is not afraid to take risks.
Emotionally closed: He tries not to show his emotions so as not to appear weak. He suppresses his pain and fear, which only makes his condition worse.
Impulsive: He can act impulsively at times, especially when it comes to preventing genocide. He doesn't always think through his actions, which can lead to undesirable consequences.
Clothing: He wears a jacket that is a mix of his original outfit and his Undertale!Frisk outfit. The jacket is half red (left side) and half white (right side). Under the jacket, he usually has a white shirt. He wears black shorts and red slippers.
Eyes: The right eye is completely black, with a red line running through its socket (as if blood were flowing from the socket). The left eye is his normal eye, usually glowing red.
Scars: He has several scars all over his body, mostly on the left side of his face and on his arms.
Facial expression: Usually sad and sullen. Often looks tired and depressed.
