When Takuya as Agunimon entered the Light Sphere of Sakkakumon, he found Seraphimon's Fractal Code and Mercurymon's subconscious. Mercurymon absorbed the Fractal Code and became ShadowSeraphimon, who immediately attacked Agunimon. No matter what Takuya did in his Agunimon or BurningGreymon forms, nothing worked. Instead ShadowSeraphimon beat him down with his hands, feets and his Testament attack. When the evil Angel used his Strike of the Seven Dark Stars attack it caused BurningGreymon to regress back to Takuya. Takuya then was about to be killed by ShadowSeraphimon when Tommy, Zoe, J.P., Bokomon and Neemon called out to Takuya, causing Seraphimon's Digi-Egg to glow. It floated up to the Light Sphere and sent a stream of light into Takuya, who Fusion Evolved to Aldamon. He easily defeated ShadowSeraphimon and scanned his Fractal Code, returning it to Seraphimon's Digi-Egg.

He could be considered, though unlikely, as the Fusion Spirit Hybrid of Steel, because of his color scheme and that during his fight against Takuya, remember that he was still utilizing both Spirits of Steel AND Seraphimon's data. Also, keep in mind that Takuya and Koji both gained the ability to become their Fusion Spirits because of Seraphimon's egg.

Also of note is how oddly weak ShadowSeraphimon was to be defeated so easily by Aldamon, which would indicate the evolution was somewhat incomplete or lacked the vital data to access the forms true abilities.
