Eugene defeated Angle, winning his cherished Olympic gold medal (per match stipulation), and starting a feud between the two. The feud culminated at SummerSlam on August 21, where Angle defeated Eugene to regain his medal. Eugene then briefly teamed with Tajiri (who, incidentally, had also previously teamed with William Regal). The team lasted until Tajiri's release in December.

On November 18, WWE.com reported Dinsmore was rushed to the hospital the previous night, after passing out in a hotel lobby in Manchester, and was suspended indefinitely. Days later, WWE.com stated Dinsmore admitted to taking prescription drugs, including somas. This coincided with the announcement of WWE's new drug policy (established as a result of Eddie Guerrero's death from heart failure, aggravated by his history of drug abuse). Striker ultimately defeated Eugene to end the feud. After appearing at ECW One Night Stand on June 11, On the September 4 Raw, Eugene and Duggan challenged World Tag Team Champions the Spirit Squad for the title, but were unsuccessful. The team split up on the November 6 Raw. After losing a rematch to The Spirit Squad, Eugene attacked Duggan, turning heel.

Eugene made his final WWE appearance on the August 31 edition of SmackDown!. While shooting T-shirts into the crowd via T-shirt gun, he accidentally shot Mark Henry.

On July 28, Gowen and U-Gene defeated the Ring Rydas to win the JCW Tag Team Championship. However, Gowen forfeited the championship after realizing that U-Gene cheated to win, causing U-Gene to attack him and disband the team.

Professional wrestling style, persona and reception During his run with WWE, Dinsmore's character was "Eugene", an overly-excited and "special" person who could outwrestle anyone in the ring, based upon some people with intellectual disability. The idea of the gimmick came from then OVW trainer Rip Rogers, who was inspired by his autistic son.
