I don't see what the MC has to do with Bryan Mills or The Raid...
He's not an uber-fighter, doesn't have a lot of skills...
(And Tony Jaa is OVERRATED)
And if you want to talk about awesome fight scenes that could be linked with the main theme of DA...
I would have talked about "Oldboy".
Mystery, kidnappings, sex, incest...
But mainly, that kind of fights don't have a place in the noir genre...
Our "hero" usually is just an average joe... gullible, broken, rough around the edges...
Don't take my previous comment too seriously, it's not as if I expect the MC to become a human killing machine. As you've said before, a Punisher approach would be nice, but then again, The Punisher isn't an "average man" at all, neither would be John Wick, even if he may look like an average man at first glance.
On another note, it would be nice if the last fight finished at the Millenium Tower or vs a 100 Yakuzas, MWAHAHA I've just been playing Yakuza games lately. (BTW, this isn't a real suggestion, I actually like the way the story's going, besides there are various different paths depending on your choices, and I think that Philly_Games shouldn't feel discouraged to create his own vision).
PS: Tony Jaa's not The Raid's MC,that would be Iko Uwais. Whereas Jaa is known for Muay Thay, Uwais is known for Pencak Silat.
PS2: Kiryu-Chan can look Noir enough in a trenchcoat, or dressed as a cab driver, another Noir MC that would be great, would be Spike Spiegel, but then again...I would be feeling empty due to the lack of a dog like Ein.
