Luppi temporarily replaces Grimmjow Jeagerjaques as the 6th Espada when Grimmjow is demoted by the loss of his arm. Luppi is a youthful Espada with short black hair and a rather feminine face. The remains of his hollow mask (a top row of teeth) rests on the left side of his head, looking like a hair comb or barette. Luppi's attire consists of long sleeves that fall past his hands, hiding them. The location of his hollow hole is hidden from view, but his Espada tattoo is prominently displayed on his right hip.
Luppi's zanpakutou is Trepadora, a short blade resembling a kodachi or tantou that he wears close to the armpit. Trepadora is released with the command "strangle". When Trepadora is released, eight tendrils sprout from a carapace mounted on Luppi's back. Luppi's mask also changes, growing into a makeshift helmet. Luppi can freely and independently control these tentacles to attack his opponents, making him skilled at group combat. The tentacles can also grow spikes to cause additional damage. The carapace can also rotate, allowing Luppi to spin the tentacles like helicopter blades.
