Card Trivia:Supreme King Gate Zero
- This is the first Pendulum Monster with a Pendulum Scale of 0.
- This monster's name is based on "zero", whereas this monster resembles the number "0".
- 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 reduce any damage to zero.
- In the anime, this card's Pendulum Effect also prevented the player from Pendulum Summoning if they controlled a monster, thereby giving them "zero" monsters to Pendulum Summon; however, this anime Pendulum Effect is implemented in the OCG/TCG Pendulum Effect of "Supreme King Gate Infinity".
- 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 reduce any damage to zero.
- This monster and "Supreme King Gate Infinity" 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 Fusion or Synchro Monster references how Yuri merges with Yugo in the Yu-Gi-Oh! ARC-V anime.
