Did you know that not all cannibals are alike? An exo-cannibal eats only those outside his immediate social circle (e.g., his enemies), while and endo-cannibal will eat those within his immediate social circle (e.g., his friends). A pan-cannibal is indescriminate, and will eat anyone.
The world's most infamous cannibal is the legendary, 19th century, Fijian chieftan, Udre Udre, as described in an article from the FIJI TIMES:
Udre Udre holds the Guinness World Record for "most prolific cannibal."
The name Udre Udre still stirs fear in people even though he is said to have died and is resting in Rakiraki.
From stories passed down generations, Udre Udre was from Draqara in the Nakauvadra mountain range. It was the time when tribal war was going on and people were killed, cleaned and eaten beside a river — a spot known as Kanakana Bridge. … Udre Udre and his people moved to Korolevu and some went to Lovoni ...
"When Udre Udre and his group settled at Korolevu, they used to beat the lali an idiophonic Fijian drum from the top of the hill and it could be heard as far as Yaqara," said Epeli Bukadogo of Vatusekiyasawa Village.
"From what I was told by my forefathers, the beating of the lali meant Udre Udre was looking for someone to eat.
"People used to hide their children, who even went and hid themselves when they heard the beating echoing through the mountains.
"He would go for those who were fat and healthy, even children. If he wanted to eat someone, he would just get that person."
Mr Bukadogo said Udre Udre killed his victims by smashing their heads on a sharp stone. …
Udre Udre reportedly ate between 872 and 999 people.
He kept a stone for each body he ate. The stones were reportedly placed alongside his tomb in Rakiraki.
According to Udre Udre's son, the chiefs of Rakiraki would go to the battlefield along with Udre Udre and they would each give him every body part of their victims, especially the head, preserving what he couldn't eat in one sitting for consumption later.
