Card Trivia:Number 61: Volcasaurus


 * In the anime, when this card removes an Xyz Material, this card eats it. The two spikes on it's chest open and shoot flames to destroy an opponent's monster, inflicting damage to the opponent.


 * So far this is the only "Number" to be FIRE.
 * This is also the one of the first two "Number" Monsters to be Rank 5 and a Dinosaur. The second is "Number 19: Freezerdon".


 * Rikuo's "Numbers" monster is this card, whose number could be seen 180° clockwise of "19", the "Number" of his tag partner.
 * They're both Dinosaur-Type Xyz Monsters whose themes (Lava and Ice), Attributes, and 2500 ATK/DEF are reversed.
 * #61 could be shaped as a volcano while #19 could be shaped as an icicle.


 * This card's effect is similar to the effect of "Destiny End Dragoon" and "Infernity Doom Dragon".


 * This monster's initial form is a sphere of mostly-solidified magma with two orange glowing spikes on the top and bottom. The sphere "erupts" into its true form.


 * This monster sort of resembles Gigan from the Godzilla Franchise.


 * This card will be available in Duelist Pack 12: Yuma Tsukumo. Yet Yuma himself has never used it in a duel, though currently it is located in his Extra Deck via Astral.
