Arc inspired by early 90s beat'em ups

Preparing for the introduction of Street Justice to AE, I started to make a short arc (two or three missions) inspired by the classic beat'em up genre.
The plot is quite simple: an criminal organization known as Deadly Dragon is roaming the streets and spread mayhem. They are now organizing a fighting championship known as "the World Warrior". The only chance to limit the influence of the organization is to win the championship, but the competition is tough.

My question to you is if you have any ideas of subplots and dialogs that would spice up such arc. Subtle references to well-known games and movies would be good too. My point of view is that many players appreciate a story better if they have something to relate it with, regardless if it is complex or simple.

Could have a random girlfriend get smashed in the stomach and hauled off from your oh so cool garage that you happen to come out of ten seconds later.

I don't have any ideas for you but I'm looking forward to see the finished arc.

Double Dragon, Ninja Gaiden, Street Fighter, and Mortal Kombat references would all be pretty fitting. Maybe even Guilty Gear references.
