Remember, this is a multiverse that has vampires, ghosts, the holy grail, ultimate beings, genderswapped histroical and mythical figures, a high school student who can kill ANYTHING UNDER GAIA, a woman who is pratically immortal, a man who can survive being destroyed to his ankles by one of Earth's nature spirits, magic, and Archer. The fact the genderswap of a genderswap of Saber-Nero looks nothing like the bust doesn't even raise an eyebrow.
