wait marvel does do reboot here article that lists some of them oh thou I guess it depend on how one would define a reboot
HEROES REBORN (1996)
After dying in the final battle of the
Onslaught event, a handful of classic heroes—Iron Man, Thor, Captain America, Hulk, and, most importantly, The Fantastic Four—were transported to a pocket universe created by Franklin Richards (Sue & Reed’s occasionally omnipotent offspring). Marvel rebooted the
Avengers,
Iron Man,
Captain America,
Fantastic Four, and
Thor titles, giving them to Jim Lee and Rob Liefeld (who never met a foot he could actually draw)—both former Marvel employees who had left to start their own studios. Liefeld only lasted two issues before Walt Simonson at Wildstorm took over.

In a “No more Multiverses” proclamation that would make Scarlet Witch proud, the powers that be decided to literally mash Earth 616 with the Ultimate Universe, leading to their mutual destruction. Saving them both, at least partially, was none other than Baron von Doom. With the launch of
Secret Wars, Marvel grabbed hold of all their various side-titles, tossed them in a bag, and shook vigorously. The resultant comics, part of the
Battleworld event, were a mix of old 616 heroes and villains, escapees from newer offshoot realities (like
Old Man Logan), as well as new and forgotten characters alike (like Singularity and America Chavez in
A-Force). But
Secret Wars and
Battleworld, despite Marvel assuring us they were the new status quo, were never meant to be anything but a stepping stone that led to the…
