SkullKnightmon is a major antagonist in the 2020 reboot of Digimon Adventure:. He serves as an agent of Devimon.
SkullKnightmon is a Knight all clad in black. He has two bloodshot eyes on his chest and carries two red spears.
After Nidhoggmon was destroyed by Omnimon, Devimon sends his agents, Skull Knightmon, Velgemon and Calmaramon to attack the Digidestined.
After Velgemon was destroyed by the combined attacks of MetalGreymon and WereGarurumon (thanks to Angemon’s holy power), SkullKnightmon suddenly appears and steals Angemon’s Digi-Egg. He attacks them with his Nastagia attack, and escapes on horseback with DarkMaildramon. He takes the opportunity to imprison Angemon’s Digi-Egg in Devimon’s castle.
After Splashmon’s defeat, Yamato, Taichi, Takeru, and their Digimon partners arrive in Devimon’s tower (located on top of ElDradimon), where they confront SkullKnightmon. Greymon and Garurumon put up a great battle against SkullKnightmon until he has the upper hand in brutally beating them. They Digivolve to MetalGreymon and WereGarurumon to get their upper hand against SkullKnightmon. However, Devimon, who was watching the duel, supports SkullKnightmon by Digivolving into AxeKnightmon. He brutally fights MetalGreymon and WereGarurumon, while Yamato and Takeru manage to reclaim Angemon’s Digi-egg. As WereGarurumon was pinned by AxeKnightmon’s dark arrows, Yamato upgrades WereGarurumon by becoming his Saggitarious Mode, and manages to overpower AxeKnightmon. Just then, Angemon’s Digi-Egg glows and wipes out AxeKnightmon, destroying the tower in the process.
However, AxeKnightmon survives and resurrects the defeated NeoDevimon and grants him the power to Digivolve to Done Devimon.
