A cruise ship? Big deal. Compare that to being able to tank a blast capable of tearing billions of tons of rock from the moon without being harmed... Now that's a feat, and the Hulk may be more powerful than that currently. Just accept the fact that the Hulk would tear her limb from limb if he got serious on her, they are not in the same class, you need to deal with that, she would never be able to physically contain a planets explosion due to sheer strength. The Hulk over powered the explosion, what's there to get? I'm not trying to be lippy, or make it seem that I'm even steamed about this topic, I'm just telling you that her star bolts aren't going to put him down.
Storm and the Human torch combined blasts and it did nothing, are you saying that she can do better by herself? Carol also has huge feats, she smacked the crap out of Sentry once, and nearly one-shotted the Grey Hulk. Let's stick to averages. Starfires average showings aren't that big, yet you completely ignore those ones and supplant them with her major ones.
Yes she can fly but as you've seen, so can Sentry, Ironman, Gladiator... etc the list goes on. Here's a fun-fact, the Hulk can leap to the point of flight, which means that he could catch her in mid air, bring her down and KO her before they reach the ground. This is of course if you believe that since she can turn a cruise ship to paper that it means that she can tank a planet busting punch. See what I did there?
You should allow this thread to sink into obscurity.
