Cold as the planet of his Uranian Medal, Sombra is cool and never loses his temper in battle. Outside of the battles, he is always with his own thoughts gazing far away, searching for meaning in his existence and inner peace. He is always the first to sense danger and is the most agile of the group. Garra fell in love with a human and Dr. Mente made Sombra face him in a deadly fight. Sombra always believed that the reason for his existence was to be a killing machine, but after seeing Garra fighting for love, he had doubts. What Sombra fears the most is the emptiness inside his heart. The last thing Sombra wants is to live as just a failed laboratory experiment.
During his training, Sombra learned to use the Uranian Medal and thus has the ability to create ice and control it. His main technique is the Uranian Ice.
