History Recap / Supergirl2015S3E10LegionOfSuperHeroes

* BattleThemeMusic: The Legion gets Reign's attention by blasting Music/BonJovi's "Livin' on a Prayer" from their ship's speakers. He probably took a page out of [[Film/GuardiansOfTheGalaxy Star-Lord's book.]]

** J'onn, again, forgets that he has powers at all. His first line is that he doesn't think they have a chance at beating Reign without Supergirl. Except that, as we've seen, J'onn by himself is easily a match for a Kryptonian. This is somewhat [[JustifiedTrope justified]] considering that Reign ''[[UpToEleven is on a whole different level.]]'' When they actually battle, Reign defeats him after a short struggle.

* HealingVat: Kara is kept in one aboard the Legion's ship for half the episode, while recovering from the Reign's beatdown.

* FaceHeelTurn: Thomas Covill is disappointed with Supergirl's failure to stop Reign, so he decides that he will follow Reign instead.

* TheDragon: Covill submits to Reign, becoming her right-hand man.

** Ayla Ranzz (Lightning Lass) from the ComicBook/{{Legion Of Super-Heroes}}, planet Winath and the Blight exist in this continuity.

** Apparently, Mon-El forgets that he has SuperSpeed, as he runs towards Reign at a fairly leisure pace, even for a human.

* FutureImperfect: According to the Legion, at some point in the future, a terrible catastrophe will befall humankind, resulting in much of knowledge and history being lost. Thus, only bits and pieces are known, and Mon-El is responsible for reintroducing some of the cultural knowledge in the 31st century. For instance, they seem to treat Music/BonJovi lyrics as words of profound wisdom.

* MultinationalTeam: So far, the known members of the Legion include a Daxamite (Mon-El), a Titanian (Imra), and a Coluan (Brainiac 5). During the fight with Reign, they were also working with a Green Martian (J'onn) and a Kryptonian (Kara).

** Ayla Ranzz -Lightning Lass- from the ComicBook/{{Legion Of Super-Heroes}}, planet Winath and the Blight exist in this continuity.

* NoSell: Reign towards Red Sun grenades and Kryptonite. Only when it is directly injected into her bloodstream, she is affected, but she can still use her flight power and overcomes it relatively quickly on her own.

* SociallyAwkwardHero: Brainiac 5 is a little like that. He even does the super-nerdy thing like signing Alex's cast in binary.

* BaitAndSwitch: During their first scene, it seems like Ruby is running away from Samantha in terror. Turns out they are only playing a game.
* BankRobbery: Reign responds to a bank robbery in progress, only for it to turn out to be a trap by DEO with many of the people inside (robbers, clerks, customers) being DEO agents in disguise.

* ClarkKenting: No one recognizes Reign as Samantha, even though she stands fairly close to some of her friends. Then again, Supergirl manages to pass as Kara with just a pair of glasses. At least Reign has a mask and changes her voice and ties her hair back and does a 180 on her personality.
* CliffhangerCopout: The previous episode ended with an ominously-still Samantha ignoring Ruby as she spoke to her and drew closer, then Samantha suddenly spinning to face her. And then...presumably she apologized for being distracted and they went about their day, because it's not touched on again.

* ExcuseMeWhileIMultitask: During the Legion's fight with Reign, Brainiac 5 splits his attention between helping Kara find a way out of her coma and flying the ship. When Kara figures it out, she tells him to leave her and focus all his attention on the battle.
