One Night Stand
2006 | Rob Van Dam | WWE Champion / ECW Champion
RVD was the only man to hold both the ECW Championship and the WWE Championship at the same time. At One Night Stand 2006, Rob Van Dam faced Cena in an extreme rules match. The conditions were extremely hostile for Cena with signs threatening to riot if he had won.
Edge made sure this did not happen by spearing Cena with a motorcycle helmet on. Paul Heyman counted the pinfall and Rob Van Dam was declared WWE Champion.
The next night on ECW, Paul Heyman revived the ECW Championship and simply awarded it to the high-flying ECW alumni. This made Van Dam double champion for 22 days. On Raw, he lost his WWE Championship in a triple threat match with John Cena and Edge. It would be a lot longer before he would lose the ECW Championship to The Big Show though.
His push with two titles was cut short and many believe it to be down to his shenanigans outside of the ring. The fact still remains the he is the only person to ever hold these two titles simultaneously and that certainly speaks for the unbelievable talent that Rob Van Dam displayed in his storied career.
