Today was announced Number #81 (hachijuuichi) Choudokyuu Houtou Ressha - Superior Dora. That Number belongs to Anna Kozuki. It have Rank 10 and required 2 Level 10 Monsters. It have 3200 ATK, 4000 DEF and Earth Attribute. Why won't appeared in Anime. If that was happened, Yuma could suffers a Heart Attack from shock. He must destroys Number which had over 3000 ATK.
number 99 is utopic dragon not whatever that says and some of the card names may be lost in translation but most of these are in English now so theres no excuse
if u pay close enough attention there are actually not 100 under hundred number there are actually only 85 plus the barian numbers and the chaos versions of the monsters if u pay very close attention the start bouncing numbers 4ward at number 70 then it starts skipping numbers
If we're also going by lore, getting into base forms alone there is 113 separate ones alone for the base forms which are the numbers that are Astral's memories, the Mythirian Numbers, the Numeronius Numbers both real and fake, the Barian Over Hundred Numbers, Number 62 (I do not count it as a memory for the reason it's actually a legend), The Numeron Dragon, Numbers 1000 and Number F0 (similar situation as 62 but for Yuma)
