- This monster resembles the Summon Alexander from Final Fantasy Franchise.
- This monster's name and design reference the trickster giant Utgaroar (also known as Utgard-Loki) from Norse mythology, as well as his illusory castle. His name literally means "Loki of the Outyards". He got this name to distinguish him from the god Loki, the companion of Thor.
- It is also named after Utgard, a stronghold located in Jötunheimr, home of the jötunn, from Norse mythology.
- The symbol from "Generaider Boss Stage" appears in this card's artwork, albeit the upper right circle is highlighted light blue. This circle represents Jötunheimr.
