Percy Jackson and the Olympians: Legends

Heimdall has curly white-blond hair like ram's wool, alabaster colored eyes and golden teeth. He wears a padded cloth tunic and woolly leggings, all beige to pick up the colors of the Bifrost. He is mentioned to have fluffy eyebrows. Magnus describes him as "the goofy guy you didn't want to sit next to on the school bus."

Heimdall was a strong and loyal warrior, with a high sense of honor. Although being extremely powerful, even for an Asgardian, he loyally served Odin, having swore an oath of faith to his king. However, his true loyalty mainly lied with the throne of Asgard, rather than Odin personally. Heimdall was ultimately philanthropic as he would put his people and his allies before himself. Heimdall was a great friend of Thor and showed much care over him as he watched over him.

Heimdall is the Norse Aesir god of vigilance, the son of Odin and the nine mothers. He possesses the resounding horn Gjallarhorn and the golden-maned horse, Gulltoppr. He keeps watch for the onset of Ragnarök while drinking fine mead in his dwelling Himinbjörg, located where the rainbow bridge Bifröst meets Asgard. Previously, Heimdall graciously granted Magnus Chase, Samirah, Alex Fierro, Halfborn Gunderson, and Amir his blessing to cross the Bifrost bridge. He meets them all at the top, where he proudly shows his collection of selfies.
