Morlun vs Gotham

Morlun is walking around killing people already down Killer Croc, Bane, Peguin, and about 60 innocent people. Morlun is making his way to Arkam Asylum to kill all the inmates. This is Morlun when he fought wakanda. Batman can't call for outside help but he can rally other Gotham heros and also Gotham Villains can Batman pull it off?

I dont think batman can really do much unless he somehow gets help from a mystic in gotham. Morlun was a supernatural threat and he only got defeated by 2 things:

1) a specific scenario when he tried to feed on peter's irradiated blood.
2) the others .... basically a plot device.

Other than that, he just tanked everything that was thrown at him

Well, Gotham's screwed.

If its pre DCnU, well, Jason Blood and Ragman are the only two mystic based heroes of note in Gotham....doubt that's enough, unless Etrigan can BFR him to hell.
