OK, lets check Batman,s equipment .... 5 batarangs and a smoke pellet, it's a poor day for Batman when thats all he's got. He would lose this fight just through being underequipped.
Batman keeps pace with all the superpowered heroes and villains around him mainly by having more gadgets than you can shake a stick at!
Let's face it, Marv could beat Batman on his own with this gear. after Batman has used the smoke pellet and the 5 batarangs and realised their uselessness he would have to go toe-to-toe with Marv and no matter how good he is Marv would tear him apart (especially with a hatchet as a bonus).
It would pretty much be a quickdraw challenge between Batman and Hartigan, if Bats can disarm Hartigan quickly enough he wins, if not then he suddenly misses a large chunk of his body. (I know he wears body armour but Hartigans Magnum makes a mockery of this)
Bats would probably be able to handle Miho, sure she is fast but then so is Batman and he is much tougher than her, her ranged weapons owuld be nigh useless against him as his would be against her. It would come down to close combat which you would expect Batman to win.
All 5 at once? Batman has lost unless he gets a better arsenal!
