"
Fire Fist", known as "
Flame Star" (炎(えん)星(せい)
Ensei) in the
OCG, is an
archetype of
FIRE Beast-Warrior monsters first introduced in the as Magazine Promotional Cards, but from different magazines and later expanded in
Cosmo Blazer. In the
OCG, every "Fire Fist" monster, except "Horse Prince", "Lion Emperor" and "Spirit", is named after the 108 heroes of
Water Margin, the "
108 Stars of Destiny", mixed with names of animals; the "Horse Prince", "Lion Emperor", and "Spirit" are characters from the novel, while the "
Fire Formation"
Spell/
Trap Cards are named after celestials. Roughly a third of the heroes, the "Heavenly Spirits", have been released as of now. They are played by
***** Geki in the
Yu-Gi-Oh! D Team ZEXAL manga.
As seen in the artworks, every "Fire Fist" monster has a flame which represents a monster/animal form, except "
Spirit" who is a flame. Most "Fire Fist" monsters have a counterpart monster in the archetype with the same Level, ATK value and flame color. They can be seen together in the "Fire Formation" cards.
Currently only twenty-one "Heavenly Spirits" and three other characters have been released.
