Cloudfill Palace, HQ, Morcubus Island, Morcubus' Lair
Halo returns in MySims Agents 3:World Domination as the main peacemaker for your team. He tries to settle disputes between you and MorcuCorp by travelling with you to Morcubus Island and entering his lair. This attempt is failed no matter what you choose him to say when he converses with Morcubus.
He can't be defeated as he is a major member of your squad.
