The Void is a huge hole located in the bottom of the Nexusverse. It is bigger than any other Omniverse in the Nexusverse, it is also lead by Exdeath. The dark depths of the void is so strong that it's the only way to kill Hypneegee but the Nexusverse would also die with him, so Pureegee and Gabgee made a huge lock to keep the void shut. The lock is protected by millions of Weegee and Gabgee clones.  It slowly grows... people say it'll be the size of the whole Nexusverse in about 10 years.
