  • In the OCG, this is the only "Number 39" monster that is not a "Utopia" monster by name, but treated as one by its effect. As such, it is the first card in the OCG to possess an archetype condition.
    • In the TCG, this card does not have an archetype condition, as its name was changed to include "Utopia" in its name.
  • This is the only "Number" monster, whose number forming animation during its summoning sequence, ends with the numbers having an afterimage in various colors, instead of a single color.
  • This is one of only two cards which, in its card text, mentions a specific number which is not a multiple of 100. The only other card to do so is another "Utopia" evolution: Number S39: Utopia Prime.
  • This is the first and only card to increase a player's LP by a fixed amount of a number ending in 50 through a card effect, rather than by half of an odd number.
    • This is the only "Utopia" card that has an effect to increase LP.
    • The amount of LP gained is half of the original attack of "Number 39: Utopia" and "Number C39: Utopia Ray." (The anime effect was to gain half the ATK of the monster that was Summoned by the effect.)
  • This card's Japanese name, "Beyond The Hope", appears to be an allusion to the song "Beyond The Time", the ending theme of the film Mobile Suit Gundam: Char's Counterattack. The battle that introduced this card in the anime is highly reminiscent of the final battle in that film - in both cases, the protagonist is a peacemaker with a white-armored machine, while the antagonist is a sympathetic villain with a larger red-armored machine plotting to crash one world into another.
