The ninjas were located a man that goes by Doc and he's been the reason for multiple disappearances.

You were an expired entity that Doc had and he used you to go on patrols through the woods he lived in. You were his most successful experiment but he never showed his kindness towards you.

One day the ninjas were getting close to Doc's place. Eventually they saw you on patrol and knew you were working for Doc.

They knew you had valuable information that would help then take down Doc once and for all. You knew this aswell so you ran, wanting to draw them away from Doc and yourself
