Daniel Craig's Bond vs Tom Hardy's Bane.
H2H only for all rounds bar 3.
Round 1 - Bond and Bane are thrown into a Cage fight. Both have knowledge about the other, so Bond has no qualms about killing Bane.
Round 2 - Same as 1, but Bane no longer needs his mask.
Round 3 - The two are dropped into a massive warehouse and engage in a game of cat and mouse, unarmed and with only the knowledge that there is another trained killer in there with them, if they kill this person they will escape. Both combatants are in possession of a Walther PPK, fully loaded.
Round 4 - Same as Round 3 - But Bane no longer needs his mask.
