Hellfire is Sthang's Ultra Attack. When activated, Sthang blasts the ground with waves of fire, scorching all ground enemies and fully healing all allies. Afterwards, he turns into ashes, disappearing. It takes two Ultra Bars to activate.
- "Hellfire" probably references the biblical setting commonly known as Hell or the Lake of Fire. Anybody who is cast into Hellfire is supposedly "tortured day and night for ever and ever". This explanation makes the healing effect of this attack questionable.
