Card Trivia:Megarock Dragon
- This card has a Reptile counterpart, "Evil Dragon Ananta".
- This has a counterpart in terms of appearance, "Gigastone Omega".
- A Deck can have from 40 to 60 cards. Supposing that a 60-card Deck has only Rock-Type Monsters, including Megarock Dragon, and that all of them, except for the latter one are on the Graveyard, multiplying 59 Rock-Type Monsters x 700 would give us 41300, the highest amount of ATK and DEF this card is able to have in the game.
