Feitan is a recurring character in the anime series, Hunter x Hunter. Feitan is a member of the Phantom Troupe and is currently the acting leader of the group until the original leader returns. Feitan’s main Nen ability is called Pain Packer which allows him to conjure a protective armor after taking damage. He is then able to transform all the pain he received as a giant ball of fire, much like the sun to scorch his enemies to ashes.
