* The ending for Double Dragon II on the NES and TurboGrafx16 [[spoiler:[[http://www.youtube.com/watch?v=DSuVH4YgIx0 when Marian]] [[http://www.youtube.com/watch?v=EmjKbof0Kpw is brought back to life]]]]. This makes it all the more heartwarming if you played the [[BittersweetEnding original arcade version of II]] first. The music helps a lot too.
* Double Dragon Advance throws another heartwarming. After beating Willy, Billy and Jimmy fights for the hand of Marian, but [[spoiler:rather than one of them being 'dead' so the winner takes everything, Marian stops the battle and made the Lee brothers realize that fighting each other isn't good, and then they continue to be friends with Marian and still stay as brothers. In other words, Marian made them realize the sacredness of 'Bros before Hoes'!]]
