In different degrees, the three most prominent star-faring empire-building alien races are traditionally (but by no means exclusively) associated with an Earth superhero team: the Skrulls with the Fantastic Four, the Kree with the Avengers (though they have troubled the FF as well) and the Shi'ar with the X-Men. Trying to build other established associations gives mixes results, however. Aside from Lilandra abducting Reed Richards to stand trial for saving Galactus' life, there is almost no interaction between the Shi'ar and the FF (though Gladiator did have an epic battle with Sue when she hosted the Uni-Power and was briefly Captain Universe). But if you were to switch things up, how would you establish long-term alternative ties. How would the Shi'ar interact with the returning Fantastic Four or Future Foundation? And beyond "The Three", which other races would you like to see interact with which teams? The Kymelians and Power Pack, the Brood, etc.
