The Chief Labespent is a somewhat powerful leviathan that simply doesn't seem too interested in much. They don't usually pick any fights, even when threatened, until they are attacked. They also seem forgetful and will just stop what they're doing sometimes as if they either lost interest or simply forgot what they were doing. There are some Chief Labespents that are aggressive however, and they show how strong these strange leviathans can get. The Chief Labespent makes its first appearance in Monster Hunter: Wyvern Instincts.
