The Flash: Supergirl's Sacrifice

Synopsis
THE DIMENSIONAL RIFT LOOMING OVER CENTRAL City is closed, thanks to last-second heroics from the Flash and Team Arrow. But they still have plenty of chaos to deal with: Cisco and Curtis are lost in time, a maniac is terrorizing the citizens of Star City, and the Flash is running out of option to save everyone. And when Anti-Matter Man arrives on Earth-38, the Flash and his friends race across dimensions to join forces with Supergirl, and Superman, and their allies at the DEO - but even with all hands on deck, will it be enough to stop a force of pure decay?

Trivia

 * Ambush Bug broke the fourth wall two times:
 * The first time he criticized the fact that his suit is copyrighted by Warner Bros and that he deserved his own TV series on The CW.
 * The Second time he criticized the fact that his suit is green by stating "It ain't easy being green, you know. Just ask J'onn J'onzz. Or that Brainiac 5 kid. Although he's really more a bluish color in this particular version, isn't he? And even then, only when it's in the budget that week."
 * He didn't meet the Martian or the Coluan, so it's a clear reference to the fact that he is aware of being a simple character.
 * Despite being an antagonist, Owlman is one of the main characters and some chapters are from his point of view.
 * His role in this Crisis is similar to the one of Lex Luthor as both are a villain that has an important role in their respective Crisis.
 * According to Brainiac 5, Supergirl was destined to die if the Anti-Matter Man entered their Earth's atmosphere.
 * The ending Cliffhanger implies that Supergirl has sacrificed herself by fighting the Anti-Matter Man.
