Let's say the X-Men have set up the field as they want and are lying in wait for Superman. They see big blue coming up on the horizon, so without further ado, Emma Frost and Professor Xavier begin attacking his mind.
While Superman pauses in midair, battling an invasion of his will, Storm and Iceman freeze the air, slowing him further, while Ororo drops him out of the sky with a hurricane-force gust of air.
As Superman lands facedown, Nightcrawler teleports on top of him, right on cue, with Wolverine in tow. Logan pops his claws and brings his fists down, meaning to put nine inches of adamantium right through Supes' brain. Tink, nothing happens. Superman turns around and swings, smashing Wolverine and knocking him into Kurt. They go flying and land somewhere in Calgary.
Cyclops fires his most powerful blast, consuming pretty much the whole field. Power that could level mountains blasts Superman further back, while Storm rains lightning on him and Iceman pours on the freeze blasts.
They manage to throw the Man of Steel back, a stream of optic energy carrying him across the field in a big red tide, but he lands on his feet, now righted. Grimacing, he fires his heat vision once--having already pinpointed Professor Xavier and Emma Frost on the other side of the field, a single heat beam to the forehead effectively lobotomizes the two of them. (Even if Emma had been in her diamond form, which negates her psychic powers, it wouldn't have stopped the beam).
With the assault on his mind ended, the rest of this fight takes about a split second. Scott realizes his mentor and girlfriend have just lost most of their higher brain functions when he's knocked out, Storm following about a second later.
Thinking quickly, Iceman dissipates himself, becoming one with the air moisture. Unpurturbed, Superman ascends ever higher into the stratosphere. At the peak of his flight, he pauses and takes a single, deep breath....
And sucks Bobby (as well as the oxygen for a good surrounding mile) into his lungs. Before the rattled Iceman can do anything, Supes gives the "ice breath," blast of his life, tilting his head up and firing Iceman into the nether-regions of space.
As for Beast? He realized a week ago what a bad idea this was, and now Hank McCoy is busy relaxing in Aruba with a fine cigar in his muzzle and a frothing daiquiri in his paw.....
