The Red Dragon Clan was first introduced in Mortal Kombat Deadly Alliance, they are not good people. Daegon leads the group with passion, with Mavado second in command. Hsu Hao himself would hope to one day be promoted to Mavado's rank, being that they both were recruited around the same time. Luckily, it would never come to this. Hsu Hao and Mavado were both brutally murdered.
Daegon however, lives. Worst of all, it appears he may be interested in resurrecting Outworld's one true ruler.
