Story
When Astral first appears to Yuma Tsukumo in Yu-Gi-Oh! ZEXAL, it is revealed that he is trying to retrieve his lost memories, which have transformed into the 99 "Numbers Cards". When they are summoned their respective number is printed in their user's hand. It is said that these Number monsters cannot be killed with cards in this world. However. when two or more Numbers confront themselves in a Duel they'll fight each other to consume one another. When they're defeated in a Duel they're absorbed into Astral.

It is for this reason that Astral teams up with Yuma.

Members
Each Number monster has its respective number showing on a part of its body.
