Vladimir Kozlov

On the December 6 episode of Raw, Kozlov and Marella captured the WWE Tag Team Championship by defeating the defending champions Heath Slater and Justin Gabriel, Mark Henry and Yoshi Tatsu, and The Usos in a four-way elimination tag team match. At TLC: Tables, Ladders and Chairs, Kozlov and Marella defeated Slater and Gabriel via disqualification to retain the title. The duo lost the tag team titles back to Slater and Gabriel at 2011 Elimination Chamber. Kozlov was supposed to be a part of an eight-man tag match at WrestleMania XXVII. However, during a WrestleMania Axxess match, he was attacked by The Corre, Kofi Kingston took his place at the event.

On August 30, 2011, it was announced that Prudius would be making his first post-WWE appearance on September 3, working for the Japanese promotion Inoki Genome Federation (IGF) under his new ring name Alexander Kozlov. He made his debut on September 3 at Genome17, losing to Eric Hammer in under three minutes. On December 2, Kozlov defeated Montanha Silva. On May 26, 2012, at the IGF Genome 20, Prudius battled Jérôme Le Banner for the IGF Championship, but lost in three minutes. On July 10, Prudius got a rematch for the title, but lost again to Jerome Le Banner. He has not wrestled since his last match for IGF, electing to focus on work as an actor and stuntman.

When the ECW brand came to an end, Kozlov, along with all other ECW talent, became a free agent. Kozlov would make his debut for the Raw brand on March 8, 2010 in a handicap gauntlet match with John Cena competing against Kozlov, Mr. McMahon, Batista, Mark Henry, Drew McIntyre and Jack Swagger. On the May 3 episode of Raw, he would team again with his former tag team partner William Regal to face the WWE Tag Team Champions The Hart Dynasty, Kozlov and Regal were defeated when Regal tapped out to David Hart Smith's Sharpshooter.

Continuing his pursuit of the WWE Championship, Kozlov competed in and was unsuccessful in winning a Beat the Clock Challenge match against ECW Champion Matt Hardy for another title shot. This led to the two meeting at Armageddon, where Kozlov gained his first pay-per-view win by defeating Hardy in a non-title match. Kozlov competed in the 2009 Royal Rumble match, entering as the sixth participant, but was eliminated by Triple H after eliminating The Great Khali, Carlito, and Montel Vontavious Porter. He then qualified to be part of the No Way Out Elimination Chamber match, where he was pinned for the first time after receiving a Last Ride from The Undertaker, though he still remained unpinned in one-on-one competition. Kozlov's undefeated streak in televised singles competition ended on the March 2, 2009 episode of Raw, in which he was defeated by Shawn Michaels; this match was for the opportunity to face The Undertaker at WrestleMania XXV. His first televised singles loss on SmackDown came against The Undertaker himself on March 13.

On April 13, 2009, Kozlov was drafted to the ECW brand as part of the 2009 WWE draft, as ECW's only pick of the night. Shortly after the draft, his character was tweaked to further highlight the training he received within the Russian military. He won his first match on the brand when he easily defeated a local competitor. On the June 30 episode of ECW on Syfy, he teamed with William Regal to defeat Christian and Tommy Dreamer. His first defeat in singles competition on ECW came on the July 9 episode of ECW, where he lost a #1 contenders match to Christian for Tommy Dreamer's ECW Championship at Night of Champions.

On the April 4, 2008 episode of SmackDown, Kozlov made his official WWE debut as a villain, with the unique quirk of having no entrance music and no Titantron video – his "entrance" consisted of complete darkness except for a solitary spotlight following him to the ring. He defeated Matt Bentley in his first match, and over the following weeks, Kozlov would go on to easily win several matches, first against local talent and then established names including Colin Delaney, Funaki, Nunzio, Shannon Moore, Jimmy Wang Yang, Jamie Noble, and Domino. On the July 11 episode of SmackDown, Kozlov debuted an entrance theme and Titantron video as he defeated Stevie Richards.

On July 28, 2007 in Louisville, Kentucky, Kozlov won the OVW Heavyweight Championship by defeating Paul Burchill, but gave the championship the same night to Michael W. Kruel due to an agreement they made before.

On May 5, 2006, Prudius had his first untelevised WWE match during a house show in San Jose, California, defeating Rob Conway. The next night, at another house show in Sacramento, California, Matt Striker cut a promo on Prudius, calling him a "filthy immigrant", causing Prudius to attack him. Prudius then picked up the microphone and said he that he is "proud to be in America".

On the December 18, 2006 episode of Raw, Prudius made an appearance as a WWE prospect named Vladimir Kozlov or Moscow Mauler, which became his ring name. For the next several weeks, Kozlov was interviewed on WWE programming, proclaiming his love for "Double Double E" (WWE), but also began drawing a villainous response after declaring his superiority over whatever wrestlers were competing at the time, saying "I could beat both of them". He then was taken off television for over a year while working in the developmental system and participating in a number of dark matches, including one at Armageddon 2006, all of which he won.
