Uncle Ben is one of the few characters who has never officially been brought back from the dead (I think). Which gave rise to the phrase:
No one in comics stays dead except Uncle Ben
There is a timeline, according to Uncle Ben's wikipedia page, where Ben survives but May dies:
A storyline in Friendly Neighborhood Spider-Man has suggested that Ben may be alive. This Ben, however, was actually from an alternate timeline where Aunt May died in a random accident, leaving him to raise Peter. This alternate Ben came to the 616 reality as part of a plan devised by the Hobgoblin of 2211 to defeat the Spider-Men of different eras
Is there any alternate timeline / dimension / universe in which Ben never dies and Peter grows up with both Uncle Ben and Aunt May?
