(SCP×Cuphead) Devil's First Mission (as an Involuntary Agent): Retrieving an escaped SCP-953 (March 2023)
I wish I could draw fight scenes: both of them taking on different forms as they brawl it out, SCP-953 trying to psychologically manipulate/entrance Devil, and the Devil using his growing stress/anger to deliver blasts of fire to deter her. It ends with Devil using his remaining energy to keep a weakened SCP-953 leashed with an Octopus arm as MTF operatives arrive. SCP-953 doesn't resist capture, but in her cell, she ominously express interest in the Devil as a worthy opponent. She's looking forward to a rematch and will find joy in tormenting him in future battles.
Let's just say during his time in the SCP foundation, the Devil's enemy list gets long pretty quickly.
