Hailmar greets the ninja aboard their Destiny's Bounty. He tells the group that they don't allow visitors to Shintaro due to the Dire Bats, but tells them to forget about it and introduces them to the Kingdom of Shintaro.
Hailmar introduces the ninja to Vangelis.
After Vania went after Wu and Cole, Vangelis orders the guards to prison Chompy and makes up a lie to hide the fact that he's the Skull Sorcerer. Hailmar is confused since Chompy is Vania's pet, but Vangelis double downs on his command.
Hailmar discovers Cole in the throne room along with the Upply, Vania, Wu, and Cole. He calls for Cole's arrest after Vangelis ordered him to do so, but Vania tells Hailmar it's all a misunderstanding. However, he doesn't listen and orders his men to apprehend Cole. While fighting, Chompy turns into an enormous dragon and allows Cole and the Upply to flee the throne room. Vania tries to reason with Hailmar, but he charges at Vania.
After Vania was successful in convincing Hailmar, he helps in the fight against Grief-Bringer and the Skull Sorcerer. After arresting Vangelis, he is there when Vania is crowned Queen of Shintaro.
Hailmar is with Vania when she tells him to boost security. Hailmar asks what the "Storm Amulet" is, and Cole replies that it is something that should never see the light of day.
Hailmar and some of the Army of Shintaro attends Nya's memorial.
- His helmet is the same as the one reborn Garmadon wears, albeit in gold.
- He uses the armor piece first seen on the Stone Army and currently used by P.I.X.A.L. in her Samurai X attire.
- His name means "Helmar" in Hindi, which also means "famous protector."
- He is similar to Hakim from Disney's 2019 movie Aladdin, as they are both leaders of the guards with a name beginning with Ha-. Both were also loyal to the king (or the sultan), although they were willing to betray him to help the protagonists.
The images on Hailmar need to be organized.
