mythra (massive melee) (xenoblade)
The modified version of Mythra made for Super Smash Bros. Ultimate in order to keep the game at its E10 / CERO A rating. The name is a reference to Melee, the second entry in the series.
The cleavage cutout of her blouse is covered, and she now wears black pantyhose.
It first appeared as a spirit in the base game before appearing as an obtainable costume in Xenoblade Chronicles 2, later serving as her default appearance as a playable character.
