As much as i hate to admitt it 1 wolverine is a match for the hulk seeing as wolvy can hurt hulk easily with adimantium and is faster and more tactical, but realy it shouldnt matter, because hulk should heal straight away and due to increaseing strength his speed will also graduly increase and eventuly be able to smite down wolverine. But of course this is never how it works when wolverine is in a fight against spider-man all of spidey's powers are dumbed down so he can get a hit in, when he is a fight with the hulk hulks healing factor disappears, so hulk dies of blood loss or summit.
Hulk would easily get beaten by 5000 wolvys as stupid as it seems, but doomsday i know nothing about so cant say.
