Si Xing Long
Si Xing Long is one of the seven Shadow Dragons, the fifth to be fought by Gokuu and Pan. He is the dragon of the Four-Star Dragon Ball, and is the twin brother of San Xing Long. He represents the element of fire. He was born from King Piccolo wishing for the restoration of his youth during the events of the original Dragon Ball series. His name refers to a nova, an exploding sun, referencing his incredible fire powers.
Si Xing Long is very faithful to his fellow Shadow Dragons, but also is fair to his enemies in battle, never resorting to desperate tactics, no matter what situation he is in. He will even assist his enemies if he considers his brothers’ tactics on them unfair and desperate. He is also one of the most serious dragons, rarely smiling and limiting his taunts to the heat of battle.
Si Xing Long’s abilities are all heat based. He can raise his temperature to more than 6,000 degrees Celsius, effectively making him hotter than the surface of the Sun.
