On
May 29 2006, Van Dam was selected by
Paul Heyman to be
drafted from
RAW to WWE's new
ECW brand. Upon being drafted, Van Dam became the new brand's flagship, mostly due to his prior history in ECW and his title shot against
John Cena at One Night Stand.
At One Night Stand, Van Dam defeated Cena to win the WWE Championship, his first ever World Title. Throughout the match the fans verbally abused Cena. A fan named Kevin S. Maharaj had hung a banner that infamously said "If Cena Wins, We Riot" over the balcony, with ECW announcer
Joey Styles noting, "Here comes the riot!" when Cena appeared to have the match won. After two referees were knocked out
Edge appeared from under the ring and interfered on behalf of Van Dam,
spearing Cena through a table. Van Dam then hit a
Five Star Frog Splash and the pinfall was counted by Paul Heyman, who had suddenly ran down the aisle. On the following episode of
RAW, Heyman confirmed that the title change was official, due to the match being held under "extreme rules." For the past few weeks, Heyman had hinted that the WWE Championship would be "rechristened" the ECW Championship when Van Dam won. On the debut of
ECW on Sci Fi, Van Dam was awarded the re-instated
ECW World Heavyweight Championship by Heyman. However, Van Dam decided to defend the WWE Championship separately and simultaneously, joking that "this one spins." Thus Van Dam became the first wrestler in history to hold both the WWE Championship and the ECW World Championship, and the only one to hold them at the same time.
On the
July 3 episode of
RAW, Van Dam lost the
WWE Championship to
Edge in a triple threat match that also featured
John Cena. The next night, on the
July 4 episode of
ECW, he lost the
ECW World Championship to
Big Show after Heyman
turned on him. Later on WWE.com, Heyman suspended Van Dam for 30 days without giving a reason; (
in reality, WWE suspended Van Dam for 30 days as a result of
his recent drug possession arrest) . He returned to house shows on
August 5, and returned to television on
August 8, attacking both
Sabu and
Kurt Angle during a match. His return to the ring came a week later, in a losing effort to
Sabu in a ladder match for number one contendership to the ECW World Championship.
Van Dam slowly worked his back into the championship picture. In October, Van Dam defeated The Big Show in a non-title match to regain the number one contendership. Having the option to pick a date, Van Dam announced the title match would occur at
December to Dismember. Heyman, however, had the option of picking the match type, and announced that the main event would be a six-man
Extreme Elimination Chamber match. At the event, Van Dam was eliminated third from the chamber.
Later in December, Van Dam would once again earn No.1 contendership to the ECW World Championship, but this time by a fan poll. Van Dam would go on to get three matches against ECW World Champion
Bobby Lashley, coming up short each time.
Rob Van Dam would later join the
ECW Originals along with
Sabu, Tommy Dreamer, and
the Sandman. The ECW Originals would then begin a feud with the
New Breed (
Elijah Burke, Kevin Thorn, Marcus Cor Von and
Matt Striker). The two teams would face off at
WrestleMania 23 in which the ECW Originals won. With this win, RVD tied with John Cena as one of few to go four WMs in a row without a defeat.
Following Vince McMahon winning the ECW World Championship at Backlash, RVD and the other ECW Originals made statements on WWE.com about Vince killing ECW. The ECW Originals all competed in a four way dance to decide who would take on
Vince McMahon the next week on ECW in a title match, which Van Dam won after a five-star frog splash on Sandman. However, Rob Van Dam instead had to face Vince McMahon,
Shane McMahon and
Umaga in a 3 on 1 handicap match, which Rob Van Dam was unable to win.
Rob Van Dam received a concussion during a match with
Randy Orton (
kayfabe). Orton further attacked Van Dam after the match due to the comments Van Dam made on WWE.com about the lack of respect Orton displayed towards
Shawn Michaels, who also suffered a
concussion (kayfabe) at the hands of Orton. Van Dam once again faced Orton at
One Night Stand, this time being a Stretcher Match. Although it looked as if Orton was going to win again, Van Dam gave a kick to his head, and was able to push the stretcher across the line for the win. However, despite winning the match, Orton continued to attack him, ending with a Elevated DDT off the barricade and onto the concrete floor. This would be Van Dam's last match. Van Dam's contract ran out as of the 8th of July 2007, and he declined to re-sign with WWE. On
September 5 2007 his profile was removed from WWE.com.
