Model F

Fighting Fefnir - 'The Flame Mega Man'

History
Model F was stolen in the first ZX game by Serpent and split into two halves to create Fistleo the Predatoroid and Flammole the Moleroid. Once attained by Vent/Aile, he/she gains access to Model F's abilities by Double Megamerging it with Model X to create Model FX.

His password is Flamma Wies, a corruption of 'Flamma Vis', which means 'Power of Flame' in Latin.

In Mega Man ZX Advent, Biometal Model F is used against its will by a new Chosen One by the name of Atlas. Her manifestation of Model F bears closer resemblance to Fefnir, with the helmet ornaments mounted on the front instead of the back. In Ashe's story, Atlas can use this Biometal to lay bombs.

Trivia

 * Model F is one of two original Biometals that produces armor that is not the same color as the armor of the original Reploid (Fefnir has red armor, but Model F produces orange armor). The other is Model P.
 * An interesting note when playing through Lurerre's stage is that it is much easier to go through if the player Megamerges to Model FX. Because Model FX is of the Fire element, it makes the player invulnerable to the slowing effects of the numerous Moth Queens' attacks through out the stage essentially melting the snow crystals that falls from them on contact.
