Also known as: モデルL, Model_L
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).
