Eaten by Chaka, one of Arabasta's two guardian warriors, this Zoan fruit turns its holder into a large black jackal, offering both a full-beast and a hybrid form at will while sharpening the wielder's strength, speed, and predatory instincts.
Ranked among the Zoan fruits, this power reshapes its eater into a big black jackal, with a complete animal shape and a hybrid one both on call. Chaka is the one who consumed it, and because jackals belong to the same biological family as dogs, the name keeps the canine thread running through the Inu Inu line.
The change raises Chaka's power, pace, and sensory acuity in the manner of any carnivorous Zoan, leaving him far better suited to physical clashes than the milder animal types. He tends to summon the shift when feeling runs high, having morphed into the jackal once Crocodile stoked his fury, then fusing beastly muscle with his swordsmanship. The boost to speed and strength let him spring onto the roof of the Arabasta castle where Crocodile sat. Only one named attack has ever been displayed. In Narikiba, Chaka takes his full jackal shape, grips his sword between his jaws, and charges to rake his target with the edge. That strike accomplished nothing against Crocodile, who turned his body to sand so the blade slipped straight through. Apart from the usual seawater weakness, no special flaw has been noted.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
Chaka of Arabasta wields the fruit. He embodies the jackal, one of the kingdom's pair of guardian spirits, alongside Pell, whose own falcon form comes from a different fruit named Tori Tori no Mi, Model: Falcon. That pairing nods to the Egyptian gods Anubis and Horus in turn, linking Chaka's power to notions of protection and standing.
Chaka, one of Arabasta's two guardian warriors, is the character who ate the Inu Inu no Mi, Model: Jackal, gaining the power to transform into a large black jackal in both full-beast and hybrid forms.
The Inu Inu no Mi, Model: Jackal is a Zoan Devil Fruit that increases its user's strength, speed, and predatory instincts, letting Chaka combine jackal-enhanced physicality with his own swordsmanship.
Chaka's only known named attack is Narikiba, in which he takes his full jackal form, grips his sword between his jaws, and charges to slash at his target, though the move failed against Crocodile, who turned to sand to avoid it.
Beyond the standard Devil Fruit weakness to seawater, no special flaw has been noted for the Inu Inu no Mi, Model: Jackal.
Chaka's jackal form makes him one of Arabasta's two guardian warriors, paired with Pell, who wields the falcon-based Tori Tori no Mi, Model: Falcon, echoing the Egyptian gods Anubis and Horus as symbols of protection.
