This card shares the same ATK and DEF as "Stardust Dragon" and "Elemental HERO Neos", as well as the same ATK as "Dark Magician". These cards are the signature cards of Yusei Fudo, Jaden Yuki, and Yugi Muto, respectively, who are the previous protagonists from the first three series of the anime. This card is Yuma Tsukumo's signature card.

The artwork book of Kazuki Takahashi released on December 2011 revealed that this card originally had the number "3" instead of "39", as the artwork shows "03" on Utopia's shoulder.

If one puts the words for "3" and "9" together, they form "sankyū", which sounds very similar to "Thank you", referencing how Yuma saves people from the "Numbers" (or other dilemmas) and is therefore a hero.

This card is one of the first three Xyz Monsters to be released. The second is "Gachi Gachi Gantetsu" and the third is "Grenosaurus".

This monster appears to have taken its form and name from Yuma's kattobingu, as he never gives up until the very end.

This card's English name, "Utopia", is a literary term used for a perfect society or community. The word originated with Sir Thomas More, in his 1516 novel of the same name.

"Numbers" take the form of their original owner desires. In this case, it is to remain strong, never give up, and protect. The result is a Warrior-Type monster who can negate attacks by detaching an Xyz Material from it, preventing monsters from being destroyed, and protecting a player from direct attacks.
- This card's effect may represent Yuma himself, as by detaching one Overlay Unit, it negates an attack, protecting the monster or person being attacked, like how Yuma would go out of his way to protect his friends or anyone else; as well as his refusal to give up even when a situation is at its grimmest for him.

"Utopia" appears to be the most loyal Number to Astral. In episode 37, when Dark Mist attacked Astral, "Utopia" protected him. Also Utopia acted completely on his own as both Astral and Dark Mist were clearly surprised, implying that "Utopia", like "Number 83: Galaxy Queen" and "Dark Mist", has a mind of his own.

As Dark Mist can be seen as the dark counterpart to Astral, "Utopia" can be seen as the light counterpart to "Number 96: Dark Mist".

This card is the first card to be the Cover Card of two different Starter Decks.
- In Starter Deck: Xyz Symphony, this card's Set Number is YS12-EN039, which is the same as its number.

This card is the second ace card of a main protagonist to have its name changed in the dub, the first being "Dark Magician".

This is the first Xyz Monster to be released as Gold Rare in the TCG, in Gold Series: Haunted Mine.
