Pierre Marceau

WWE NXT (2013–2016) Marceau was documented to have been with WWE since September 2013. WWE describes him as having formerly played rugby, been in the French military riot police and worked in a psychiatric prison.

On the 8 May 2014 episode of NXT, Louis formed an alliance with Sylvester Lefort as two French characters representing 'the Legionnaires', and later participated unsuccessfully in a 20-man battle royal for a NXT Championship title shot. On the 26 June episode of NXT, Lefort and Louis attempted to attack Colin Cassady, who was saved by Enzo Amore. This was a continuation of Lefort's feud with Amore and Cassady back in September 2013.

At NXT TakeOver: Fatal 4-Way in September 2014, Lefort lost to Amore, and was thus supposed to lose his hair as per the match stipulation. However, Lefort ran away and Louis instead lost his hair and eyebrows via Amore and Cassady's hair removal cream. Louis initially persisted in his alliance with Lefort, hiding his lack of hair with headgear and a wig, only to lose to Amore in a singles match on the 25 September episode of NXT when his baldness was exposed. On the 16 October episode of NXT, Lefort accidentally knocked off Louis' wig, this led to Louis snapping and attacking Lefort. On the 30 October 2014 episode of NXT, Louis' character, now without entrance music, began screaming "You did this to me!" This coincided with Louis defeating Lefort in a singles match. This storyline led to Louis' character turning crazy, being described as a "baldy Kane version 2.0" by the Pro Wrestling Torch Newsletter.

On the 27 November 2014 episode of NXT, Louis lost to Tyler Breeze, who constantly taunted Louis as being ugly. This led to a storyline where Louis could not be found, only to resurface in January 2015 stalking Breeze from afar. Yet the storyline with Breeze was dropped when Louis returned months later in June, still bald and deranged, tagging again with Jason Jordan in a loss to the Vaudevillains. On the 12 August 2015 episode of NXT, Louis lost to NXT Champion Finn Bálor in a non-title match.

He then wrestled a string of tag team matches during the rest of the 2015 summer winding down toward the October month and into the fall season. Victories included winning a match with Sawyer Fulton and Solomon Crowe against Bull Dempsey, Mojo Rawley and Tucker Knight on October 30 and a win against Oscar Vasquez on December 3.

Louis wrestled only three more matches during the new year. All three matches occurred over the month of January 2016. Louis lost all three of his tag team matches. It was reported on February 5, Louis was released from the WWE.
