Great Jaggi, along with the Great Baggi, may attack other boss monsters instead of focusing solely on the hunter, indicating a highly competitive and intelligent demeanor. It can also call its pack of Jaggi to its aid at any time with a loud, resonating roar. Being a larger and more powerful dominant male of Jaggi and Jaggia, it is considered by players to be the boss of these monsters. Its alpha status is much more prominent than that of previous Dromes, as it features many of the characteristics of full-fledged boss monsters — the ability to become enraged, limping when weak, and having a breakable part. One should note that the Great Jaggi can be summoned by the Qurupeco at the Deserted Island, Sandy Plains and the Misty Peaks.
The Great Jaggi is the head of a Jaggi pack. At a certain age, males leave the pack to live on their own for a period of time before returning to fight for the right to be a leader. They have a very commanding presence. It is said they can call and give complex orders to their pack with their howls and barks.
The commanding alpha male of Jaggi packs. Most males leave the group upon reaching maturity, returning to compete with others. The dominant male then becomes a Great Jaggi. Apparently, they can issue fairly complex orders via howling.
Great Jaggi will occasionally attack other boss monsters such as Rathalos or Zinogre if in the same area.

Great Jaggi has two different roars. Its first roar sounds like a the call of a howler monkey, and summons Jaggi to the area. Its second roar sounds more like a howling wolf, and will cause any Jaggi and Jaggia in the same area to gang up and attack the hunter.
