A stupid ass superhero
from the South Park
episode Coon 2: Hindsight. He flies around the world providing hindsight after every catastrophy that happens, but doesn't actually do anything helpful. Instead of helping the fire department save lives, he just started bitching about how it could have been avoided. Not to mention how "useful" he was during the gulf oil spill
Rndm Citizen: Look!! It's Captain Hindsight!!! Captain Hindsight: That building shouldn't have been built there. It prevents fire trucks from getting closer to that other building. My job here is done. Captain Hindsight away!!! Everyone: Thank you Captain Hindsight!!!!!!
