!!Tropes that apply to Ms. [=McCormick=] include:
* {{Adorkable}}: As Olive (and, to an extent, Sierra herself). Acting adorkable is what landed her the role of Olive in the first place (specifically, she talked about tigers for minutes on end).
* {{Bookworm}}: Again, both Sierra herself and Olive.
* CelebCrush: According to her Website/{{Twitter}}, [[Film/OzTheGreatAndPowerful James Franco]] [[http://instagram.com/p/ftd0qhk8Aw/ (whom she met in October 2013)]], [[Series/{{Scrubs}} Dave Franco]], Creator/AdamLevine, Creator/JosephGordonLevitt, [[Music/TheLonelyIsland Andy Samberg]], [[Series/{{Heroes}} Thomas Dekker]], and Creator/CillianMurphy.
* CelebrityEndorsement: [[http://www.peta2.com/heroes/sierra-mccormick-adoption-ad/ She's appeared in a peta2 adoption ad]].
* CreepyChild : Her role as {{Lilith}} in ''Series/{{Supernatural}}'' was nightmare-inducing, a testament to her acting ability, [[TheCutie as she is adorable anywhere else]].
** Also as "Creepy" Connie Thompson in ''Series/{{Jessie}}'' (albeit [[LighterAndSofter to a]] ''[[LighterAndSofter far]]'' [[LighterAndSofter lesser extent]]).
* TheCutie
* {{Fangirl}}: She's a {{Series/Super|natural}}[[Series/DoctorWho who]][[Series/{{Sherlock}} lockian]], and she loves Music/{{Maroon 5}}.
* GamerChick: Again, both Sierra herself (who loves ''VideoGame/AnimalCrossing'') and Olive.
* GenkiGirl: It really shows when she plays [[Series/ANTFarm Olive]] and [[Series/{{Jessie}} "Creepy" Connie]], and in [[http://youtube.com/watch?v=LnNg-up7rK8 her various]] [[http://youtube.com/watch?v=eYdpL3jLJWk Disney Channel]] [[http://youtube.com/watch?v=-rX0UWFtMwI intros]].
* HeterosexualLifePartners[=/=]PlatonicLifePartners: To most of the ''A.N.T. Farm'' cast, but particularly to Music/ChinaAnneMcClain (whom she's been been best friends with even before ''A.N.T. Farm'' due to their appearance in an episode of ''Series/HannahMontana''), Creator/JakeShort and Allie [=DeBerry=].
** She's also this towards ''Film/RamonaAndBeezus'' costar Joey King.
* HiddenDepths: Among other things, she plays the piano and speaks Spanish.
-->"[[https://twitter.com/SierraNMcCormic/status/381256913419137024 Yes, I sound incredibly formal, and the diction is somewhat basic, but yes [I can hold a conversation in Spanish].]]"
* IdolSinger: Unusually for such a prominent {{teen idol}} on Creator/DisneyChannel, {{averted|Trope}} so far.
* {{Meganekko}}: Sierra and Music/ChinaAnneMcClain play this [[http://antfarm.wikia.com/wiki/Chierra/Gallery?file=China_Anne_McClain_and_Sierra_McCormick.png#Modal adorably]].
* OlderThanSheLooks: She looks like she's 12 and sounds like she's 10, but she's really 17. The fact that she's only 5'2" certainly doesn't help.
* RapunzelHair: A more realistic version of the trope. Her hair is nearly to her waist even when braided or curled.
* SpiritualSuccessor: She's most frequently considered one to Music/EmilyOsment (considering she almost resembles Emily appearance-wise).
* TeenIdol: Although she's been acting since she was nine.
* TrademarkFavoriteFood: Orange Tic Tacs.
