>>7857369as others have pointed out MASK, Action Man, and Inhumanoids can be folded into the GI Joe sphere pretty easily, Rom can tie into either the Transformers or Power Rangers stuff since it's also a space robot franchise(inded Rom could easily be used to facilitate a crossover between those two franchises), and depending on how you handle them Visionaries, Micronauts, and Jem could be tied into any of those other ones(or even into properties like Magic: The Gathering, Dungeons & Dragons, or even the Pastel Talking Equines)
and I'm probably forgetting about a couple Hasbro properties that could also get involved, basically Hasbro's stuff is perfect for weird crossover stuff, it just needs to be approached correctly
