SkullKnightmon Mighty Axe Mode is an Enhancement Digimon. It is Axemon's "Pulverization-armament Mode" (粉砕戦集形態 Funsaisenshū Keitai?), which exploits its sturdy body to be transformed into a weapon, the "Bigaxe". That battleaxe, larger than an ordinary Digimon's body, exhibits more than enough weight and stiffness to pulverize everything. It can not only be wielded by SkullKnightmon, but can also attack autonomously as a living weapon, displaying its well-coordinated combination.
- Axe Rider: Charges with the Bigaxe held forward.
