Card Trivia:Sephylon, the Ultimate Timelord
- This monster's name is based on the Sephirot, an alternate name for the Tree of Life, the ten emanations in the Jewish Kabbalah.
- Fittingly, in the Yu-Gi-Oh! 5D's anime, when this monster is Special Summoned via the effect of "Infinite Light", a tree structure appeared with the other ten "Timelord" monsters (representing the ten emanations of the Jewish Kabbalah) depicted on the circular patterns.
- This reference is maintained in this monster's OCG/TCG Special Summoning effect, which require the player to have ten or more monsters in their Graveyard.
- Based on its position on the tree, this monster is based on The Almighty, Judeo-Christian God "Yahweh" or "Jehovah", but it received its name from the Sephirot to make it less offensive.
- Fittingly, in the Yu-Gi-Oh! 5D's anime, when this monster is Special Summoned via the effect of "Infinite Light", a tree structure appeared with the other ten "Timelord" monsters (representing the ten emanations of the Jewish Kabbalah) depicted on the circular patterns.
- This is the only "Timelord" monster whose artwork shows it from an angle rather than front on.
- This is one of only two "Timelord" monsters to not have an equal original ATK and DEF of 0, the other being "Sandaion, the Timelord".
- Despite its status as the higher level "Timelord", this is the only "Timelord" monster that does not have built-in protection from being destroyed, or an effect that prevents its controller taking battle damage from battles involving it. In the Yu-Gi-Oh! 5D's anime, it needs to banish one other "Timelord" monster to grant itself the built-in protection the other "Timelord" monsters have.
- Despite being in possession of the most powerful of the four Duelists from the future in the Yu-Gi-Oh! 5D's anime, this is the only one of their signature cards that is not Level 12, the other three being "T.G. Halberd Cannon", "Malefic Truth Dragon", and "Meklord Astro Mekanikle"; also, it is weaker than "Malefic Truth Dragon" in terms of ATK and DEF.
- In the Yu-Gi-Oh! 5D's anime, this monster's attack name is "Akashic Storm", which references "Akasha", the Sanskrit word meaning "aether", the basis and essence of all things in the material world, and the first material element created from the astral world. It is known as the "fifth element", the other four being WIND, FIRE, EARTH and WATER.
- Fittingly, all ten original "Timelord" monsters possess one of the aforementioned Attributes, with this monster and "Sandaion's" LIGHT Attribute referencing DIVINE or "aether".
- This monster, "Arcana Force EX - The Light Ruler", "Arcana Force EX - The Dark Ruler", "Odin, Father of the Aesir", and "Sandaion, the Timelord" have the highest original ATK (4000) of all Fairy monsters in the OCG/TCG.
- In addition, this monster, "The Light Ruler", "The Dark Ruler", and "Sandaion" also have the highest original DEF (4000) of all Fairy monsters in the OCG/TCG.
