This is end-of-series Alita and pre-Nu52 Midnighter. No prep, fight takes place in an abandoned Gamorra City. No door technology or help from his ship for Midnighter, otherwise standard equipment for both. Both are willing to kill. Fight starts with them 100 feet from each other with no knowledge of their opponent.
Apologies if this is a stomp, I haven't read either in a bit!
