I think the Vok = Swarm was a later retcon by writers of convention/magazine fanfic (which makes its canonicity dubious at best). However, it was one of the earliest points at which the writers interacted with fans via BBS’s, and at least one member of the fan community was credited as a lore consultant, and helped them add more details from the original cartoon and comics. Simon Furman, who wrote most of the original Marvel run, actually wrote the S3 finale.
