Heimdall

Heimdall was described as a loyalist and true believer in Odin's cause. As such he is incredibly loyal to Odin, but he will try to go against Odin's will if he senses a threat to the All-Father. He is snarky, condescending, arrogant, and cruel. This is best seen when he belittled Atreus and Thrud as he knew that they are inferior to him in power. Despite his power, however, Heimdall is somewhat cowardly and fearful of people of greater power,His foresight is something he held in great confidence as it was the one power that made him untouchable, above everyone else. Due to his invaluable, irreplaceable position as Odin's mind-reader meaning Odin and his allies could never truly get rid of him, coupled with his abilities contributing to a record of having never lost a fight, Heimdall's ego grew massively. This escalated to the point that he became extremely arrogant and fond of bullying others around him simply because he could get away with it. He has a habit of giving insulting and cruel nicknames to belittle everyone around him,
