• This is the cover card for Generation Force.
  • This is the first cover card for a booster pack to debut in a manga since "X-Head Cannon", "Y-Dragon Head", and "Z-Metal Tank" debuted in Advent of Union, a gap of over nine years.

• This is the first WATER Attribute monster to be a cover card on a main series Booster Pack.

• The number 17 can be seen on one of its horns.

• The number 17 may refer to it being the 17th Ghost Rare released.

• This is the first Xyz Monster to be the cover card of a Booster Pack.

• This is the first WATER Attribute Monster to be a Holographic Rare.

• This card is the first revealed member of the "Numbers" archetype.

• This card having 3 pairs of wings and arms probably have some relation with its Xyz Material Monsters as this card uses 2 Level 3 Monsters.

• After this card's ATK increase via its effect, it has 3000 ATK, the same as "Blue-Eyes White Dragon", "Armed Dragon LV10" and "Red Dragon Archfiend", which were the signature cards of the previous series rivals. Interestingly enough, all of these monsters are Dragon-Types.
  • However, unlike all the 3 above cards, "Leviath Dragon" is not a rival's signature card, due to it being used only for a single Duel before absorbed by Astral following its user's defeat. Also, all the 3 above cards has their original (printed) ATK as 3000, while "Leviath Dragon" needs its own effect to reach 3000 ATK.

• This monster has a cry very similar to that of "Stardust Dragon".

• In anime, when this card removes an Xyz Material Monster, it eats the Xyz Material Monster.

• This card's name comes from the mythical sea creature Leviathan, which explains this card's Attribute.
  • The other use of the name Leviathan is a book by Thomas Hobbes about the need for a strong central power in government to control the chaos of the masses. The cover art of this book depicts the "Leviathan" not as a sea monster, but a giant king whose body is made up of the subjects of the king who has gained their collective power, which is possibly referenced in this card's effect to use its Xyz Material Monsters to increase its attack.

• This monster's horns resemble Ryoga Kamishiro's hair style, if Ryoga's head was viewed from above.
