Armadiko

Beyond his sheer bulk, Armadiko could pass for any common armadillo. Coloring like lipstick rings his mouth, deepening the impression that he is female, and yet the plates of his tough, armored shell bear the kanji meaning male.

A timid, withdrawn sort, he speaks in tones so soft and gentle that many mistake him for a woman.

In the lead-up to the Fourth Shinobi World War, Don, Chuji, and Hippo Boss come to blows over who has won Armadiko's heart. Stepping in to end the squabble, King orders that the female they are quarreling over be fetched so she can name her choice. The moment Armadiko turns up, King is stunned and enraged to find who it is, and it emerges that he too carries feelings for Armadiko. To general astonishment and Condor's delight, Armadiko settles on Naruto Uzumaki ahead of every suitor, alarming the young man as the pack readies to pummel him. He bolts, Armadiko trailing behind, and the creature is soon found nestled against a shaken Naruto while the rest of the animals file into the temple. Once inside, as Naruto sets about an ecological survey, Armadiko keeps trying to slip off, and Naruto can hardly tell whether the creature is male or female, its manner clashing with the character on its shell. Even when B puts the question to him, Armadiko will not expose its genitals. Soon after, tremors from Deidara's blast rock the island and Manda II's strike tips the animals over; while Yamato's fast reaction spares most of them, Armadiko is flung down and knocked out, and in that state he is finally shown to be male, to everyone else's letdown.
