Rosalind Lutece

Rosalind Lutece is a respected quantum physicist. She was always curious about multiple realities from a young age. Through experimenting with atoms, Rosalind invented the 'Lutece Field', a wonder that allows large structures to suspend up above the ground. This allowed the floating city of Columbia to stay amongst the clouds. Later, Rosalind was able to bring in Robert Lutece, a male version of herself, from an alternate reality and into hers. He is her 'twin brother'.
