Charlotte is a large, bulky, and muscular Arrancar. His mannerisms and dress style border on those of a stereotypical drag queen. He has long, wavy purple hair, large glossy lips, icy blue eyes, and curly long eyelashes. While his Hollow hole is not visible, his Hollow mask remnants resemble a small tiara with horns, and his Arrancar outfit is customized with feminine motifs. He has a large amount of pubic hair when not released.
Charlotte believes beauty is derived from a person's heart and personality, leading the first part of his battle with Yumichika Ayasegawa to be little more than the two shouting insults at each other. He is very vain and flamboyant, believing himself to be the "most beautiful being in all creation", and refers to himself as "princess". Like his fellow Fracción, he holds his master, Baraggan Louisenbairn, in high regard, referring to him as "his majesty". Charlotte has the odd habit of giving his attacks very long names, believing himself to be talented at naming things. He holds his hair in great regard, only releasing his Zanpakutō when Yumichika ruins it. Despite this, just before his death, he displays respect for Yumichika for hiding his Zanpakutō's true power despite being cornered during his fight.
