Card Trivia:Number 92: Heart-eartH Dragon
- This card is the cover card of Cosmo Blazar.
- The "False" part of this Monster's name probably refers to Dr. Faker's name.
- The "Heart-eartH" part of this monster's name probably refers to Heartland which was founded by Dr. Faker.
- The capitalization in "Heart-eartH", is probably because the 2 words are anagrams.
- In Japanese, the number 9 can be read as "ku" and 2 as "tsu"; together, it reads kutsu, which sounds similar to kuzu, the Japanese word for scrap.

- The "9" in the 92 might refer to its rank while "2" might refer to it being the 2nd "Number" Dr. Faker used.

- The way that this card was Summoned by the effect of another monster after the latter was destroyed may be a reference to how "Shinato, King of a Higher Plane" was Special Summoned after "Shinato's Ark", which was being used Noah Kaiba's Deck Master at the time, was destroyed in the Virtual World arc of the original series.
