The Xenovoid contains the Ultravoid.
Deformation[]
When an Ultravoid was destroyed by a black hole of a Hypervoid, it can be merged by other black holes from Hypervoids from other Ultravoids and destroy more Ultravoids. This process take from 1 millillion years to 1 yoctillion years, it takes so long because the Xenovoid itself is very, very big.
Likewise, it can destroy a part of the Xenovoid, but it cannot destroy more. This scenario can happen milliillions of times until the entire Xenovoid is destroyed (this scenario can be in its Omnivoid just because of a black hole).
