Prior to signing with Apex Caliber Wrestling (ACW), Yugi Mutou and Atem were two people in one person considering the former had the latter as a spirit within the Millennium Puzzle since the early days of Mutou's fiction professional wrestling career. As within the anime/manga series, Mutou and Atem became two separate entities of their own bodies. The Fiction Wrestling Multiverse (FWM) followed canon with that and therefore, Mutou and Atem aligned with each other as "Altered Egos".
World Tag Team Champions and Various Feuds Edit
On April 5, 2013, Mutou and Atem made their debut to ACW as they were part of the first-ever ACW contest against the fellow debuting tag team of Alpha & Omega (Carter Young and Stan Terra). During the match, The Gods of Darkness (Yami Bakura and Marik Ishtar) interfered and attacked Mutou when the ref was distracted by Ishtar. Joey Wheeler and Tristan Taylor ran to Yugi's help, but Bakura and Ishtar escaped before they can get to them. Terra took advantage of a distracted Atem and hits a spear on him to pick up the pinfall. Later that evening in backstage, Atem was assaulted by Bakura and Ishtar. By the main event aftermath, Altered Egos, alongside with The Erupting Eds, interfered Bakura, Ishtar, Young, Terra and The Wolves (Hannibal Ambrose, Seth Rollins, and Damian Reigns) from ruining the night of ACW's debut and chased them off after a clashing brawl.
