model_l_(mega_man)
Biometal Model L is the Mega Man transformation for Thetis (mega man) from Mega Man ZX Advent. It's design takes inspiration from Fairy Leviathan (mega man) from the Mega_Man_Zero series.
Vent (mega man) or Aile (mega man zx) from Mega Man ZX may also use this form, combined with Model X to transform into Model LX (mega man).
