Ever since becoming a symbiote host they forsook their human name and became Phobos, living in a world inspired by both earth-42 and earth-35525 where Miles Morales' parents are dead and the Sinister Six rule the streets. At the beginning Phobos used their power merely for survival but, after being saved in their civilian form by Miles, they bow to help him however they can, having fallen in love with the young hero. Unfortunately, they ain't quite sane so it becomes an obsession that leads them to kill anyone that dares harm him and to kind of kidnap him (they don't call it that because really where else would he go? his uncle killed his parents! they are just making sure the kid is safe!!)
Phobos' pronouns are they/them but in a plural sense, so they say "we/ours" like venom lol
Anyways they are very much a deranged yandere and a deplorable human being, but they are also kind of a self-insert to somewhat ship myself with my darling 2D wife, y'all are invited to the wedding in my basement <3
