Osiris

Osiris is a member of the Employers and one of the greater-scope antagonists of the Madness Combat series REALM.

Origin
Osiris' exact origin is unknown, but it can be inferred based upon the backstory of the Employers as a whole that Osiris was once a servant of the High until he betrayed it alongside his fellow Employers.

REALM: Illuviation
Osiris is first seen informing Ra of Sokar's takeover of Nevada. Ra remarks that Sokar is a far greater threat than they had anticipated, and Osiris states they should take action before he returns. However, Ra calls him a fool and reminds him that they cast him out of their realm once before. He then decides to observe Kelzad's fight against Sokar to see if he stands a chance against him.

At the end of the episode, Osiris is seen conversing with Ra and one other unnamed Employer. The unnamed Employer states they should interfere now that Sokar is weakened. However, Ra declares that he believes Kelzad can take of Sokar and tells his fellow Employers that they should instead reclaim what is theirs.
