Onikage

Onikage (which translates to Demon Shadow) is a ninja Duke Org.

This devious ninja Duke Org was sent by Master Org to prepare for his arrival by killing the people he believed to be traitors of Master Org. He was believed to be in service of Mandilok, but secretly caused Toxica's death and then betrayed Mandilok as he had him trapped for the Master Org to kill the traitorous Org General. He then went to kill the third traitor, Jindrax, however Jindrax used a mirror which caused a shadow of Onikage to appear causing Onikage to battle his own shadow which led to his death. He fought the Rangers with different abilities, once spawning shadows of his opponents, which when the Shadow Rangers were hit, so were the real Power Rangers. He was destroyed by the newly formed Pegasus Megazord.
