Chaka

Chaka (チャカ, Chaka), also known as "Chaka the Jackal", is one of two head guards in the Arabasta kingdom that serve under Igaram; the other is Pell. He is the acting captain of the royal guard in Igaram's absence. He ate the Inu Inu no Mi, Model: Jackal, a Zoan-type Devil Fruit that allows him to transform into a jackal or a human/jackal hybrid. Most of the time he's around with Pell, but when Sir Crocodile attacks the kingdom, he attacks Crocodile outside of the Alubarna palace - first because Crocodile's utter lack of compassion angered him and to protect the country, and then in an attempt to protect Vivi and Kohza, as well as buy them time to put an end to the battle - but Crocodile easily defeated him both times. He survived, however, and showed up later on in the Arabasta arc commanding the royal guard to stop fighting. He then appeared at Pell's grave.

His newest appearance is when the Straw Hat get their first bounty, shocked to see Robin in the Straw Hat crew.
