The characters you are referring to are few and inbetween. Marvel has an absurd amount of cosmic level characters. At least 100 of them. Pre-Crisis DC is said and done. Never again. Marvel on the other hand is fond of reinstating the Pre-Crisis characters. (i.e. Gladiator, Hyperion, Sentry)
Marvel has been amping their characters relentlessly.
Scarlet Witch used to have hex spheres. NOW she can alter all reality as she sees fits.
Magneto used to control magnetism. NOW he can create blackholes.
Wasp used to shrink to the size of a wasp. NOW she can grow to a hundred feet and fire bio-electric beams as well.
Beast used to only lift 2000 pds. NOW He can lift up to 40 tons.
Human Torch used to control flame. NOW he's a cosmic herald.
Jean Grey used to be a telekinetic. NOW she's the White Crown Phoenix.
Thor used to be the god of thunder. NOW he's insanely powerful with the OdinForce.
Storm used to control the weather. NOW she can alter the electromagnetic spectrum.
Spider-Man used to rely on web cartiriges. NOW he has organic webbing.
Gambit used to have only kinetic powers. NOW he has telepathy.
Emma Frost used to be a telepath. NOW she can turn into a diamond.
She-Hulk could lift 75 tons max. NOW she can beat the Champion and can lift the Thing's max...with one arm.
Falcon used to control ONE bird. NOW he can control an entire freakin flock.
Iceman used to be a sub-par ice manipulator. NOW his control over temperature is ridiculous.
Quicksilver used to go at 500 mph max. NOW he can break the sound barrier.
Wonder Man used to be a guy with super-strength. NOW he's a pure ionic being with immortality.
The Hulk used to be vulnerable to telepathy. NOW he's immune to telepathy.
Psylocke used to have psy-knives. NOW she has uber-powerful telekinesis.
Ridiculous.
