TBH Daredevil never fought Blackheart in a straight out fight.If he did, Daredevil would be a bloody smear in the wall. If you're talking about Blackheart's 1st appearance, Mephisto instructed Blackheart to explore all sublime forms of evil.Meph also said to Blackheart to make a hero(Daredevil) sin the most vile of sin a superhero would commit.Meph also stated Blackheart should avoid the eyes of many people for evil should be invisible.He almost succeeded in making Daredevil kill him.Good thing Spidey and his spider sense warned Daredevil of Blackheart's scheme.The other incident involves Blackheart possessing a man.Daredevil almost killed the man possessed by Blackheart.
As for this thread, does DCNU Hades operates at the same level as Hela or Pluto?If not, Blackheart wins.
