As a Sumerian, Bamora's physical appearance indistinguishably matches with that of a young female Earthling, as her body is completely humanoid with a slender build and has short, blonde hair (lime-green in the anime). The only unique characteristics that sets her apart are her magenta antennas attached to the top of her head and her green eyes that have star shape corneal reflections. In the anime, her antennae are shown glowing with some form of bioluminescence. She is greatly recognized as being very pretty by the boys around her.
