Tiny Stark then proceeds to buy out Leonard's favorite bar just to crank him.
Doesn't necessarily have to be Marvel Superheroes on Robotech Earth. The original Iron Man movie makes little reference, if any, to other superheroes. In the stand-alone setting, Stark Industries was making a bucketload of money selling arms during the Global Civil War, and then afterwards after the SDF-1 crashed, and the Unification ran into problems(SHIELD being on of the UEG agencies formed to fight anti-unification groups like HYDRA, and AIM, which was trying to steal Robotechnology secrets. Tony Stark becomes a superhero briefly before the SDF-1 launch, and spends most of his time fighting global terrorism and cleaning up the mess left him by Stane, who was making money hand over fist selling armaments and leaking robotechnology to terrorists. Lang REALLY wanted Stark on his team, but Tony, being Tony, wants to go his own way. He has a crisis of faith after the Rain of Death, because it was something he couldn't prevent, but Leonard talks him back into joining forces with the UEG on a more permanent basis, and he effectively becomes Leonard's version of Lang after the latter leaves with the SDF-1. Although the two don't get along like Rick and Lang, Tony Stark treats Lonard like he does Nick Fury in canon. and Leonard is a LOT happier that Earth seems to be better defended by the efforts of a guy who could very well be smarter than even brain-boosted Lang.
Avengers Robotech re-introduces the greater body of superheroes into the universe, and introduces the SDF-1 as just another world disruption. Bruce Banner could be a result of independent biomedical research or an early accident with Protoculture. Other alien invasions happen, but they're more X-file incidents, small and contained, and the Asgard are seen as Earth's second contact(though the Asgard know nothing of the Tirolians). Nick Fury is a professional rival of Leonard, as well as General Ross, the three constantly playing each other off against the other. SHIELD has a helicarrier at Macross Island, but it either gets destroyed earlier, or becomes incorporated into the SDF-1. The presence of superheroes doesn't really change the outcome of the Rain of Death much, because there's just so many Zentraedi, even when a greater number defect to Earth's side because the news stories of the Avengers impress the Zentraedi even more than Lynn Kyle's movie 'powers'. Late in the first War, the Asgard MIGHT show up in greater numbers, mistaking the Zentraedi for the legendary giants they're supposed to face at Ragnarok.
In fact, the fact that HYDRA and AIM survive the Rain in their secret fortified bases makes the post Rain world that much more dangerous, and it balances out the greater number of permanent Zentraedi defectors who come over to the UEG's side, and the two terrorist groups actively support the Malcontent movement while carving out their own wasteland empires. SHIELD might wind up infighting with the GMP for dominance.
After than, you can have superheroes like Antman and the like popping up as surviving special operatives or emerging post-Rain vigilantes. New kingdoms could give rise to nationalist superheroes like the Black Panther, who MIGHT be persuaded to join a global force on occasion to deal with a common problem.
And there's always the chance of Bad Things like Bruce Banner completely blowing his cool at seeing the carnage wrought by the Rain of Death and near-permanently Hulking out, going on a wandering rampage of the wastelands, and becoming a problem.
Captain America? He'd work himself half to death helping the survivors and maybe having a crisis of faith, before regaining his mojo and becoming a living symbol of the reconstruction.
The course of events can roughly follow the notes I set up for my 'Mutantech' setting, which would be the next evolution of 'Robotech Meets the X-Men' with protoculture fueling the evolution of superpowers in a mutating population.
The way I see it, though, Marvel superheroes are good at acting as a spot fire brigade than fighting off global-level threats hitting multiple targets around the Earth at once. It would take something on the order of entire Earth ARMIES equipped with Iron Man-style suits to make a real difference against , say, the Robotech Masters or the Invid, or the Avengers would have to make a very LUCKY strike at some vital target, like blasting their way into the Robotech Masters' command deck at the onset of the Second War.
DC would be in much the same sort of situation, though admittedly Superman might be able to take a much greater chunk out of the Zentraedi fleet. Givem, however, that DC had an entire ARC devoted to a hellbent alien INVASION getting fought off, they (Comic Universe DC) might do better than Movie Marvel at dealing with the Grand Fleet. But I'm NOT doing Comic Universe Marvel or Comic Universe DC fighting off Robotech foes here, these are MOVIE versions introduced as part of the Robotech Universe.
In both cases, if the Rain of Death still managed to hammer Earth, there might be a post-Rain backlash along the lines of 'Where were you heroes while we were getting blasted?' that might see many of the surviving heroes forced to hide or go into greater assimilation into groups like the GMP.
Unless, of course, you live in Gotham, in which case the Batman emerges as sort of the overlord of the city, defending it against the lawless forces outside, and establishing Gotham as its own city-state.
