  • This card contains the name of Yuma's mother "Mira Tsukumo", whose Japanese name means "future".
    • Interestingly, this can also be applied to her English name as Mira means "peace" in South Slavic languages. Not only this ties her name to "Utopic Future", but her name also refers to the entire "Utopia" archetype that is the main focus on her son's deck.
  • This card is Yuma's successor for "Utopia", and unlike the other "Numbers", this card represents Yuma's own power, which he obtained without Astral. This is apparent considering that Astral did not absorb this "Number" at the series' conclusion.
  • This card's appearance resembles Yuma himself, having a red-black-white-orange color scheme that matches his casual outfit, the collar of his jacket as part of its armor, and metal protrusions on its head resembling Yuma's hair.
    • Yuma eventually fuses with this card for his last attack on Astral, which adds the Emperor's Key to this monster's body, atop the "0" on its chest.
    • This card's ATK and effect may also represent Yuma, as he is said to not want to harm his enemies directly (thus having 0 ATK) but rather let them join his side (thus the effect that switches control of the opponents' monsters).
    • This card also references Yuma's name which contains the characters for "Horse": during the summoning chant, Yuma referred to this monster as "Pegasus" a winged horse and this card's wings become much larger and glow whenever it uses its effect or attack. Yuma's last name, "Tsukumo", can be translated as "Ninety-nine", and if one subtracts both nines it becomes "0".
    • This card also bears a slight resemblance to "Number 39: Utopia Roots".
  • While this card's "Number" was displayed as "00" during its Summon, it only appears as a single digit "0" on its body (at the center of its chest). This makes it, "Number S0: Utopic ZEXAL" and "Number F0: Utopic Future - Future Slash" the only "Number" monsters to have only a single digit on its body (all other single-digit "Number" monsters have been zero-padded so that they appear as "0X").
    • This monster's appearance and its number is based on GNT-0000 00 Qan[T] ELS Version with the swords, the wings, and the core in its chest.
  • This card shares several traits with "Ultimaya Tzolkin", the first Level 0 Monster Card. They both have 0 ATK and DEF, and a condition that treats themselves as having a specific Level/Rank other than 0. Both monsters also appeared in the final battles of their respective series.
    • Outside of these similarities, however, this monster is almost the exact opposite of "Ultimaya"; "Number F0" is a LIGHT Xyz Monster (black card frame), is treated as Rank 1 (the lowest Rank), and was used by an anime protagonist. "Ultimaya" is a DARK Synchro Monster (white card frame), is treated as Level 12 (the highest Level), and was used by a manga antagonist.
