3 WWE storylines that included real-life family members and 2 that were fake 

#2 Fake - The Undertaker and Kane

One of the most convincing fake WWE families of all time revolved around The Undertaker and his half-brother Kane. The Undertaker was unstoppable throughout the 1990s and Paul Bearer decided that it was a time that he found someone who could step up to The Deadman both physically and emotionally.

In 1997, Kane made his WWE debut after Bearer told an impressive story about how The Undertaker's younger brother had been in the funeral home when The Deadman burned it to the ground and seemingly killed his whole family. What Undertaker didn't know was that Kane had survived and that he was suffering from some pretty brutal scars.

After the issues between The Undertaker and Paul Bearer reached boiling point. his former manager then called in Kane who became his enemy for a short time, before they later joined forces as The Brothers of Destruction.

To this day, there are still WWE fans who believe that Undertaker and Kane were real brothers because Bearer's story was so compelling and there weren't any online forums to debate how real the story was.
