Only a small number of Filmon can temper their quills to their limits, achieving this Ultimate form. The quills all over Stefilmon are said to rival Red Digizoid in their sturdiness, acting as both a shield around its body and pikes boasting unparalleled attack strengths. The Hurricane Knuckles on its arms are its pride and joy, highly condensing its shed fur to form weapons. It trains diligently, dreaming of the day it can trade blows with its perceived rival, WereGarurumon. Stefilmon uses its special move Giga Crimson Dive to perform a high-speed drilling charge, hacking the enemy to pieces with bristling quills and its Hurricane Knuckles, or Vermilion Vortex to extend red drill-shaped spears from its body that obliterate multiple foes at once.
