Attack Potency: At least Small Country level+ (He was capable of attacking the likes of Fujitora, Sengoku, and Tsuru, and put up a good fight by destroying half of their forces before escaping with his life. As one of Kaido's Calamities, Jack should be comparable to other Yonko commanders such as Marco and Charlotte Cracker)

Stamina: Very High (Fought constantly for 5 days straight against 2 equal opponents who each had resting periods, along with the entire Mink Tribe dwelling on Zou. He then immediately engaged in another fight that resulting in his assumed death before being struck by the trunk of Zunisha, and was left underwater for presumably days and remained almost unphased despite severe injury to his body while also remaining in the ocean as a Devil Fruit User – weakening him to some extent and rendering him immobile)

Range: Extended melee range by virtue of his size, in mammoth form his trunk gives him extra reach

Standard Equipment: Two sickles concealed as tusks which can be used to amputate victims

Notable Attacks and Techniques

Zou Zou no Mi, Model: Mammoth (Elephant-Elephant Fruit, Model: Mammoth): A Zoan Devil Fruit. The full mammoth form granted by this fruit gives Jack a massive frame, significantly increasing his already abnormal size. Jack can level buildings with a single swing of his trunk and leave imprints of his feet on the ground just by stepping on it. However, the user is extremely heavy and slow in this form, leaving him unable to dodge high-speed attacks.
