SkullKnightmon is one of the major antagonists in the 2020 reboot of Digimon Adventure, and the dark corrupted alter-ego form of Gatomon. She serves as an agent of Devimon until it’s death and takes over as the secondary antagonist of the second half until her own defeat and reverts back to her true form, Gatomon.
SkullKnightmon is a Knight all clad in black. It has two bloodshot eyes on its 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 uses Moon=Millenniummon’s dark power to Digivolve him into DoneDevimon while he escapes with DarkMaildramon.
After Devimon’s defeat, while the Digidestined and their Digimon partners reunited with each other on the new continent, AxeKnightmon ambushes them and attacks them. Patamon digivolve to Angemon to fight AxeKnightmon, but the battle seperates the other Digidestined and their partners into separate different locations. The battle reverted AxeKnightmon back into SkullKnightmon and Angemon back into Patamon.
After MetalGreymon defeats Volcadramon, SkullKnightmon suddenly kidnaps Hikari, Taichi’s little sister, and flies away with DarkMaildramon with her. She takes her to the area where Millenniummon is imprisoned.
Taichi, Sora, and Takeru (Yamato’s little brother), and their Digimon partner come face to face with in a showdown with SkullKnightmon. SkullKnightmon Digivolves again to AxeKnightmon and starts to resurrect Millenniummon. The battle becomes ferocious when AxeKnightmon becomes gigantic and attacks the Digidestined. After Garudamon defeats DarkMaildramon, AxeKnightmon imprisons Hikari inside himself as a sacrifice. Inside, Hikari finds Gatomon’s spirit, who has waited a long time for her. Taichi, now determined to rescue his sister, allows MetalGreymon to Digivolve to WarGreymon and is able to break through AxeKnightmon’s attack and impales her through the chest, finally rescuing Hikari and destroying AxeKnightmon for good, and reverts back to her true identity as Gatomon.
