Luke Cage vs Marv...

Luke Cage (Netflix) takes on Marv (Sin City) in a fight to the Death or KO with no BFR allowed...

Pure melee combat only...

Who wins?

Cage.

Cage would have to break his neck... twice, to put him down.

Which he could easily do. Or he could just hit him really hard. Cages strength would be more than enough to kill Marv.

I plan on rewatching the Sin City films on my days off, but from what I remember Luke should cave his head in

Jessica Jones Luke might have a fight on his hands.
