Mike Raimos is a teenager living in Grand Junction, Colorado.
Mike was best friends with Shawn Raider and another boy named Evan with the three being described as "inseparable." One night, Evan dared his two friends to visit the haunted Meadows house, but Mike chickened out.
After Evan disappeared and Shawn was left traumatized, Mike lied that he knew nothing about where they had been to the police. He was eventually interviewed by hunter Sam Winchester in the guise of an FBI agent. Mike finally admitted the truth about where his friends had gone to Sam, allowing the Winchesters to figure out what was going on.
