Summary
After the world forgot him, Peter kept fighting. He was Spider-Man after all. But as the villains get worse and the heroes dwindle, Peter finally grows tired. Hasn't he done his time? He's never once shirked the responsibility forced upon him. Never once has he put himself first.
Eventually, the straw breaks the camel's back. Peter finally hangs up the cape.
Unfortunately the universe seems to disagree. When Peter wakes up in Gotham he knows he should probably find a way home. But what's the point? Normal people don't find their way home across the multiverse, and Peter is normal now. He refuses to be anything else.
So why do unfamiliar heroes keep ending up on his doorstep? And can he really turn them away?
--
In which Peter Parker just wants to retire but instead he becomes a mentor for young dcu heroes and his home becomes a vigilante halfway house
