Nexus is the devolved form of the Ultra demigod Noa, reborn in this weaker state. Nexus would resurface in 2008 to fight against a wave of Space Beast assaults, slowly growing in strength and finally regaining his long lost form Noa in his battle with Dark Zagi. Although Noa is his true identity, he is able to switch between his true form and Nexus at will.
Anphans is Nexus’ base form, a middle stage between his depowered self as The Next and his true self as Noa.
