A villianous example: M.Bison and Juri wrecking everything in sight in the 1/16/2012 cinematic trailer at the Mishima Zaibatsu. Note that up until this point, the Tekken cast has been literally walking all over the Street Fighter cast. The moment is slowly diminished when Juri's cruelty towards Xiaoyu results in Jin activating his Devil Gene and nearly killing Juri, though Dictator still knocks him through a window with a Psycho Crusher. Also, take note that this is the first time where the Street Fighter side has been shown to generally be the winning team this time around.
The four words everyone who ever played with The Dark Side wanted to hear...
Kyoufu wo oshiete yarou...note I'll teach you fear... - Devil Jin's catchphrase
Many consider Mad Gear Hideout to be one as a stage example. Not only is it well-made, it's a tremendous love letter to Final Fight fans. And that's not even considering thefantasticremixes of music from the series...
Ogre barely manages to deflect a shot from Akuma, and notes that "this planet does have some strong warriors, after all." He then tells Akuma to "tempt your fate at my hands," and the latter is seen giving Ogre an aggressive glare from a distance.
Speaking of Akuma, his ending has him face to face with a Pandora version of Oni, his ultimate form from Street Fighter IV. He dismisses it as a shadow, just before he manages to fight it.
King and Marduk's ending has them confronted by an apparition of Armor King, shortly before they destroy Pandora once and for all.
In Kazuya and Nina's ending, Nina reveals that someone else wants Pandora more than Kazuya. Having sensed this betrayal, Kazuya orders a small hidden squadron of G Corp soldiers to open fire. Seconds later, Nina is nowhere to be seen, and the soldiers are left beaten.
Similar to Sagat and Dhalsim above, Poison and Hugo decide to leave the Pandora behind, deciding that it would be better to find other ways of getting famous fast, and judging by the newspaper article that follows, they succeed.
