History Characters / BestFriendsWhenever

** [[spoiler:Averted, as it is revealed that he is nothing more than a RedHerring, and apparently, so were the Tachyon Particles]].

* NotSoStoic: For all his restraint, he will slip and act emotional during emergencies.

* TeenGenius: At the age of fifteen, he has his own lab and regularly experiments on near revolutionary technology. It was this that was responsible for the accident that allows Shelby and Cyd to travel through time.

* {{Cloudcuckoolander}}: Is normally just dim, however he will occasionally fall into this. Such as on one occasion believing if they visualise upon the model rocket he's agreed to make for Chett it will come to them. And then later trying to claim the one that Barry made was his, cause he saw it after this.

* AnnoyingYoungerSibling: To Shelby.

* AmbiguouslyEvil: [[spoiler:Evidence points to Janet having a role in the BadFuture. Janet knows about the top secret lab, she clearly didn't take kindly to children like Cyd and Shelby, and she promoted Shelby's dad to working at the lab. It stands to reason she could be the [[ManBehindTheMan mastermind behind the masked man]]. Not only is it confirmed she's behind everything, but she's after Cyd and Shelby]].

* Adorkable: Her 6th grade look. Also, any time she tries to make a pun.

* DistressedDamsel: Daisy is the archetypal example of the classic "princess locked in a tower", having never seen much of the outside world. Thankfully, a time rift saved her from that, and her new friends prevented her from going back to it again.

* OlderThanTheyLook: She's physically a teenager, but due to TimeTravel, she's technically over 500 years old.
* ShipTease: Daisy is starting to get this with Barry, hugging him after he pulled his other three friends to save her, and when she turned his own prank device against him, he's starts thinking he could be in love with her.

* SpoiledSweet: There's a bit of a "pampered princess" vibe to her, but she's cheerful and friendly all the same. Ever since she came to the present, she's wanted to spend more time with commoners.

* TheDitz: They both make [[BookDumb Naldo]] look like [[TeenGenius Barry]].

* DumbBlonde: Averted. She is far from dumb as she gets good grades, but she's still no rocket scientist like Barry and she can be somewhat naive. [[spoiler:Humorously, she pretends to be one to get answers about the BadFuture]].

* OlderThanTheyLook: She's physically a teenager (due to coming through a time rift), but due to TimeTravel, she's technically over 500 years old.

* SpoiledSweet: There's a bit of a "pampered princess" vibe to her, but she's cheerful and friendly all the same.

!! Daisy

* TheDitz: [[DownplayedTrope Downplayed]]. She seems reasonably intelligent, but she has the occasional ditzy moment (like not realizing that she was a prisoner, despite having been confined to a dungeon).

* OlderThanTheyLook: She's physically a teenager, but due to TimeTravel, she's technically over 500 years old.

* ThePrankster: In "Derby Little Secret", she pulls off an extended prank on Barry and Naldo by making them think she can knight them, then gets them to perform a series of embarrassing tasks to earn the title before revealing that she can't really knight people. She did it to prove to them that she was an example of this trope.

* EtTuBrute: [[spoiler:Shelby couldn't see him the same way after learning about him in the BadFuture, and broke up with him]].

* AmbiguousDisorder: She may have something wrong with her, as her behaviour seems to go beyond simply being weird.

* BoyOfTheWeek: Subverted. He's the first of Shelby's love interests to last three episodes.

* ChuckCunninghamSyndrome: She's conspicuously absent from Season 2, due to Madison Hu taking the lead role on ''Bizaardvark''.

* {{CloudCuckoolander}}: Makes and wears clothes from rubbish, compares herself to a dog and apparently sleeps at the foot of her parents bed. Need we go on.

* CorruptCorporateExecutive: Is the founder and CEO of Globo-Digi Dyne, a very powerful technological research and manfucture company that makes everything from computers to military defense systems. She likewise uses this to [[spoiler: create the future Lab, to experiment on Cyd and Shelby]].

* VillainWithGoodPublicity: Is a well-respected scientist and businesswoman; Barry especially practically idolizes her. Of course, she has contempt even for Barry.
