Hmm. In Marvel comics, I often see a lot of interaction between different supers - but generally it's a matter of calling on someone's expertise rather than their ability to smash face. For example, let's say Spider-Man runs into some shape-shifting aliens. He then calls up Reed Richards, who goes "Oh, those are skrulls, blah blah blah. But we're headed out to the Microverse, so good luck with those."
Often enough to be worth mention, tho' not often enough to be SOP, when things need smashing, they call upon Hulk, She-Hulk, or Thor. And a few of the comics have the headliner get on the case by call-up from someone who can't handle them. (DC does this, from time to time, too.)
