Ivankov is a large man with an afro of indigo hair, and has long eyelashes, he also has a noticeably-odd shaped chin resembling an arrowhead. His afro is large enough to hold people inside it. He has a personal Jolly Roger tattooed just below his chest.
As an okama, he dresses in reddish-purple woman’s garments with heavy makeup. To signify his queen-ship of New Kama Land, he wears a queen’s crown with a king’s crown on top.
Using his Emporio Female Hormones on himself, Ivankov can become a large-sized, relatively curvy woman. This form is more realistically proportioned (relatively speaking) than his male form, and is rather well endowed. Because of the clothes he wears as an okama, this form is also scantily dressed. Despite the changes brought on by the hormones, however, he is still incredibly tall and is at least twice, if not three times the size of the Impel Down officer Sadi.
While in a flashback as a Revolutionary, Iva has been seen wearing a cloak, and without the crown.
In the anime, when Iva turns into a woman, he keeps his male voice, unlike the other characters who are changed by his powers, although his voice sounds slightly different between male and female.
