Wolverine gets one in Marvel Zombies. He loses an arm to the Silver Surfer (but later gets to eat some of him and get cosmic powers), and confronts the Juggernaut fighting over who should eat the defeated Galactus. The Juggernaut mocks him by saying his claws can't penetrate his armor and he only has one pair anyway. Wolverine says, "Not all of you is armored", and proceeds to jam his clawed fist into the Juggernaut's mouth. He then uses his cosmic powers to blow his head to pieces. As he leaves he says, "Jerk".
The Silver Surfer fights pretty much every hero on Earth at once, and its one hell of a good fight. He manages to put a decent percent of the population down for good; impressive considering that zombieism has made them pretty much invulnerable. He's only defeated by the Hulk biting off his head.
Right after Spider-Man becomes a zombie and attacks Nova, Daredevil steps in and attacks Zombie Spider-Man. He seems totally confident that he could beat him, which is impressive considering the lack of superpowers and that Spider-Man doesn't feel pain anymore. Too bad Nova chickens out and leaves him to get eaten.
