Off the top of my head:
Angel flies. Um... at least at one time he had metal wings that I seem to recall being razor-sharp and capable of shooting the 'feathers,' but I could be mixing him with someone else. I mostly know the X-Men from one of the cartoons and the movies.
Cyclops shoots beams beams of energy from his eyes. At full power, he can destroy a building-sized combat robot in a single blast. As long as his eyes are open, he will unleash this beam of energy, so he has to wear a special vizor to regulate it. This also allows him to see without destroying whatever he's looking at, and also, IIRC, lets him control the beam better, adjusting its radius and power level. Beyond that, he's the usual team leader of the X-Men (not a power so much as a personality trait), and he has amazing luck with women (also probably not a power, but who knows).
Magneto is a villain (usually) and a mutant, probably one of the most powerful in the Marvel universe. He has almost total control over magnetism, and his aptitude with this ability goes way beyond pseudo-telekinesis that only works on metal. He can control one of the four fundamental physical forces and is smart enough to use that ability in creative ways. There aren't many abilities Magneto *doesn't* have - IIRC, he can even do a limited form of mind control by manipulating electrons in the subject's brain! At the very least he can paralyze anyone, lift any metal object through pseudo-telekinesis, cause certain chemical reactions remotely, disrupt or strengthen electricity, and interact with electronics remotely. Magneto believes mutants should be ruling humans rather than cooperating with or being slaughtered by them; he espouses this position as leader of the Brotherhood, a group of like-minded mutants. However, Magneto has been on the side of the angels when it suits his purposes, and even led the X-Men for a while!
Colossus can turn his body into a metallic substance. This gives him super strength and, in particular, super resilience. He's a member of the X-Men.
Hawkeye flies. And, and, he led the Defenders!
Captain America is a World War 2 soldier who was enhanced with 'super-soldier serum' to, IIRC, save him from injury and allow him to return to the fight against the Nazis. Probably the best way to think of him is as a 'perfect human' - in D&D terms, a character with 18s in every stat. He's technically not 'super' in that he can't do anything a normal human couldn't do, if that normal human were at the peak of physical and mental suitability for the task. His weapon is a shield, which he can throw like a boomerang or use to great effect in melee; he also has a mean right hook. Personality-wise, he's the avatar of all that's best in the American ideal. He's known as the best tactician and most inspiring leader among Marvel heroes (remember, ALL 18s, including Cha and Int
) and normally leads the Avengers, Earth's premier super team.
