The Lost King — Darius Anthom in the lore — rules the frozen wastes of Arat Prime, and he fights from the saddle of his personal Gigadesmodus: the first human boss in ARK, and the first to ride a tame into battle.
He is fought through the Red-Handed mission, started at the palace terminal. While his mount flies, nothing damages either of them — not melee, not ranged, nothing — so the fight opens as a hunt for the four power poles keeping it airborne.
The Lost King won’t give up without a fight, so be prepared to face him and his royal mount, his personal 
Gigadesmodus
While the Lost King isn't interactable, his mount becomes very dangerous while in flight due to its constant spew onto the group. That, coupled with the fact that nothing can damage them, not even Ranged weapons, and his cohorts of Thralls constantly spawning, makes them dangerous enough to deal with him.
Bringing too many players (10+) may trigger a scaling damage reduction buff on the boss, making him nearly impossible to kill.
There are no notable weaknesses formed from the Lost King's mount. However, de-powering the four pillars will force his Gigadesmodus to land, making them vulnerable to attacks until the mount flies up again.
Lost Queen immediately after it. There are no artifacts on this map's door.
Tek Rifles alike.
Started near the palace terminal — the boss teleporter is marked at 18.6 / 75.9. Ten survivors and twenty creatures maximum, ground tames only: flyers do not teleport in, and the 
Gloon counts as one. Large tames snag on the narrow ramps of the walkway, and the King will not spawn until stuck tames are freed, dead or cryopodded — carry Cryopods.
The 
Lost King Trophy — and the run itself continues straight into the Lost Queen and her rewards.
