Card Trivia:Supreme King Gate Infinity
- This is the first Pendulum Monster with a Pendulum Scale of 13.
- This monster's name is based on "infinity", whereas its appearance resembles the infinity symbol (∞) turned vertically.
- This monster's name also references its Pendulum Scale, which allows the player to Pendulum Summon monsters with every Level, and its Pendulum Effect to increase the player's Life Points without any limit.
- Ironically, despite the above fact, this card's OCG/TCG Pendulum Effect prevents the player from Pendulum Summoning if they control a monster, which was used in the anime Pendulum Effect of "Supreme King Gate Zero".
- This monster's name also references its Pendulum Scale, which allows the player to Pendulum Summon monsters with every Level, and its Pendulum Effect to increase the player's Life Points without any limit.
- This monster and "Supreme King Gate Zero" both reference the similarly-named cards, "Infinity" and "Zero".
- Both cards are used by their respective anime series' final antagonists; the "Supreme King Gate" monsters are used by Z-ARC in Yu-Gi-Oh! ARC-V, while "Infinity" and "Zero" are used by Nightshroud in Yu-Gi-Oh! GX.
- Both cards require one another to utilize their Decks' field control strategy; the "Supreme King Gate" monsters support "Supreme King Z-ARC", while "Infinity" and "Zero" support the "Darkness" Continuous Trap Cards.
- Both cards can be placed in certain Zones on both sides of the player's field and allow them to use their main "weapon" in between them; the "Supreme King Gate" monsters are placed in the Pendulum Zones to Pendulum Summon monsters, while "Infinity" and "Zero" can be placed in the Spell & Trap Zone and activate all of the "Darkness" Continuous Trap Cards between them.
- This card's OCG/TCG effect Special Summoning a Dragon Xyz or Pendulum Monster references how Yuto merges with Yuya Sakaki in the Yu-Gi-Oh! ARC-V anime.
