Chōji Akimichi (秋道チョウジ, Akimichi Chōji) is a member of Konohagakure's Akimichi Clan. Though his habit of always eating gives him a relatively large appearance, Choji insists he is not fat, instead using explanations like being "big-boned". If someone refers to him as fat, Choji instantly becomes hostile and increases his resolve to battle,[ch. 55] even killing one of the Sound Four during one occurrence. Shikamaru Nara has never found an issue with Choji's weight, instead choosing to look upon Choji's inner strength. Because of this, Choji regards him as his best friend, stating he would willingly give his life to defend Shikamaru.[ch. 190] In battle, Choji can increase the size of his body to improve the amount of damage his strikes deal upon impact.[ch. 189] He can also use his clan's signature Calorie Control (カロリーコントロール Karorī Kontorōru) which converts his body fat to chakra.
