Loyal handmaiden and servant to Hela, Leah is an Asgardian and denizen of Hel. She can be relied on to be a sounding board, and advisor to Hela. When the all father Odin's brother the Serpent Cul returns from millennia long exiles and launches a global wide terror campaign by making lieutenants out of powerful Earth heroes, it is Leah that seems to advise Hela to consider the offer by the Serpent. That it might be better to ally under him in a subservient role, as Hela and Hel owe no allegiance to Odin and the Asgardians. That Asgard and Odin owes Hela a debt they will never pay. Leah is also quick to alert her master Hela, when Loki informs her of possible war between Hela's forces and Mephisto's forces, and the involvement of the Disir. In one incident Loki would try and endear himself to Hela with sweet words of compliments before Leah would play along before attacking the trickster god's groins. Yet that moment would start the machinations of an eventual friendship between the two, both noting how their names are interesting in the context of their constant companions Ikol and Hela.
Loki would also manipulate Leah by getting her to get word to Leah that Mephisto has the Disir after manipulating Mephisto into confronting Hela over a possible alliance with Cul, whilst he and Tyr killed the Serpents servant. After the defeat of the Serpent at the hands of Thor, Hela decides to relocate Leah to Earth, Broxton, Oklahoma, where Asgard is current located. This seems to bother Leah, but she does as she is ordered. Leah is to live in a cave nearby. She and Loki have a loose form of friendship, that can be complicated at times. Leah is foreign to many of Earths ways, so is on a learning curve for human habits and stylings. Leah would also be a founding member of the short lived Magic Secret Action Squad alongside Loki, Tyr, the Destroyer and the Disir. Leah is especially fond of milkshakes.
Leah is a Marvel Comics published character created by writer Kieron Gillen and artist Dougie Braithwaite appearing for the first time in the Journey Into Mystery title, first appearing in issue Journey into Mystery #624 - Feeling Hela Good. Leah is an anagram for Hela. Leah will also occasionally act as the narrator for the issue recap page.
Introduced as a part of the Fear Itself series Journey Into Mystery tie in issues, Leah was introduced in a small and humble role as Hela's hand maiden and assistant. However her writer Kieron Gillen would have much more planned for the character and rather than stay as a minor one off character, Leah quickly developed into one of the main supporting characters of Journey. With a much younger reincarnated Loki as the protagonist of the series, Leah who was of a similar age and stature would become very important to his development as well, with Leah serving as not only a potential romantic interesting but a character to clash with at times. Leah would also have her own story as she would be transported from her familiar location of Hel to Earth and experience the idiosyncrasies of humans first hand.
Seemingly an aged version of Leah eventually finds herself in the Young Avengers book, also written by her creator Kieron Gillen. Describing what she is up to Kieron notes "Leah is the therapist, and she’s up to something. She’s definitely been pro-splitting Teddy and Billy. I mentioned that he had a therapist two issues ago so she’s been involved with Teddy for some time. Oh, and of course, Loki. To what level Loki is a villain is up to you. That’s what the next issues is about. Leah talks about a group; a group of people who have been similarly hurt by the super hero lifestyle. I imagine we’ll be meeting them quite soon."

However, a mysterious female figure is later seen working with Surtur. Surtur is using the same British gods of modernity that Loki helped earlier as his pawns. He plans to use their fire and connection to Otherworld to destroy everything. This woman, who turns out to be a resurrected Leah, is helping him. She confronts Loki, telling him that she is the version of Leah that he wrote into the Serpent's story, and because he did such a poor job writing her, she is forever a one-dimensional character, unable to evolve. She tries to kill him, but after a variety of tricks, Loki is determined to help her, and ends up going back in time to write more of her story into the history book, fleshing out her character with all the details he has come to know and appreciate about her. When he comes back, she is able to be her own person, and feels more like his old BFF once again. In order to protect her from the evil that may be coming, Loki has Hela send Leah far back in time.
