In Xenologue 2, he is seen discussing the Tempest with Veronica while disguising himself as her brother Bruno. Veronica quickly sees through his disguise and questions his true identity; as she knows that her brother is elsewhere. He then takes the forms of Sharena and Alfonse while expressing his surprise at her seeing through his illusion so quickly before he decides to settle on Anna's apparance. He tells Veronica that his name is Loki and also tells her that she will have to wait if she wants to see his true form. Loki mentions the rite for the Tempest, and Veronica agrees to do it. He expresses joy at seeing that Veronica knew about the Tempest all along and also tells her that he likes her.
In Paralogue 10, he receives Naglfar from Veronica, and claims that, with it "in hand, my king's vessel will move." In addition to this, he mentions building a bridge across the southern sea and having said king assist Veronica.
In Paralogue 13, Loki claims that he had ample time to prepare for the rite and he thanked Veronica for that. He also mentions that the rainbow bridge will become real and that their king and his forces will invade Askr.
Currently, not much about him is known other than the fact that he is capable of changing his appearance and the fact that he is knowledgeable about the Tempest and wishes for its activation. He seems to be somewhat mischievous and also seems to like Veronica.
"Loki" was the name of a giant known for his mischief in Norse Mythology, and both him and this character share the ability to deceive others by disguising as other people. Loki in Heroes is the second character named after this Norse figure, with the first being Loptyr in Genealogy of the Holy War.
Naglfar is the name of the ship Loki took during Ragnarok. Ragnarok signified the war between the gods of Asgard and the giants of jotunheim. Also, Naglfar was a ship made of nails.
- It is currently unknown if Loki has been masquerading as Bruno since the beginning of the game and thus what appearances of Bruno have been him or Loki masquerading as him.
