—Ryu Kasai's BattleCry
Ryu Kasai was one of the many personal guards that onaga had during his time as ruler. But, before he was a royal guard, he was a sorceror of Onaga's Holy Men, where he learned a variety of fire magics. Always being cold and emotionless in battle he showed no mercy towards enemies of the dragon king. He was also one of the few that knew of Shao Kahn's plan to posion Onaga but, unfortunately he arrived too late before the traitous deed was done. In a fit of rage he attacked Shao Kahn but, he was easily overpowered by him. Shao Kahn let him live but, not before tearing off his arm as a trophy for himself. Using magic Ryu was able to escape the palace and find a safe place to hide but, it didn't matter for he was slowly dying. But, by chance, he met a group of indivuals who cared for him, and constructed a metallic arm for him. After he was fit enough he left Outworld in hopes of finding allies to join him against the usurper, Shao Kahn.
