It also has a thing against "artificial evolution" (a key topic to explore in the future). All forms of the Phoenix Force of each and every given universe born and dies, are linked to the center of creation, the White Hot Room, where resides the "multiversal" nexus, soul of the Collective Phoenix Force, "the Phoenix Consciousness". It resides within the Crown, the highest realm of the White Hot Room, serving as "the Crown Chakra" of the Multiverse, and a "parental figure" of all Phoenix energy. It is in the Crown, the Phoenix attains full connectivity to all of "Existence" aka "this Multiverse", and possesses the full mobility and manipulation of "Existence". Only the most connected of Phoenix hosts can access the Crown of the White Hot Room. The White Hot room is the central birthplace, workspace and afterlife of all Phoenixes, and place of recollection and rejuvenation. The White Hot Room also acts as a "Grand Library" of all Phoenix and all cosmic knowledge. It is this, that makes the Phoenix Force one of the highest of respected cosmic entities..."
In other words, the Phoenix Force as a cosmic energy and entity, exists within its respective and specific universe, however she did adopt the idea of the Phoenix being multiversal on some level. She states it makes sense for the Phoenix to exist specific to each universe, as its the nexus of psionic energy and life force. However, as the White Hot Room is nexus of all realities (definitely multiversal), and this is the domain of the Phoenix Consciousness, then the Phoenix Conscious Spirit and nexus IS multiversal, and any Phoenix host that connects to the Phoenix Consciousness attains a multiversal status, even if temporary. While she never addressed WPOC, there's no doubt that the White Phoenix shared this powerful connection with the Phoenix Consciousness, so... I would believe that in this work at least, White Phoenix of the Crown IS a multiversal entity (despite whether or not that's true in canon).
