History Characters / TheBigBangTheory

* HollywoodNerd: Leonard's incredibly good looking, even more so when you [[TheGlassesGottaGo remove the geeky glasses]] and restyle his hair.

* CommitmentIssues: Penny has this problem, ''big time''. She and Leonard eventually works through it by Leonard putting the power to propose marriage in Penny's hands, so she won't have the weight of it on her shoulders until she decides she's ready. At the end of season 7 they mutually agree to get married.

The world famous physicist himself. First featured when Howard was assigned to help maintain his communication and life support systems when he visited the university, he has since irregular appearances.

* LivingLegend: The guys, being scientists themselves, naturally admire his genius and absolutely squee over him when he appears at Cal Tech for the first time. Even Sheldon craves his approval.

* SupremeChef: Zigzagged. According to Leonard, her brisket just melts in the mouth. However, her Thanksgiving specialty "tur-briske-fil" (turkey stuffed with brisket stuffed with gefilte fish) has to be swallowed like pills.

* CommitmentIssues: Penny has this problem, ''big time''. She and Leonard eventually works through it by Leonard putting the power to propose marriage in Penny's hands, so she won't have the weight of it on her shoulders until she decides she's ready.

Howard's overbearing mother whom he insists lives with ''him'', rather than he with her. During the show, she has never actually been seen on screen, only [[TheVoice yelling from off it]]. According to Howard, she is very large in figure and sports facial hair. Has a tendency to treat Howard as if he is still a child, which he is often annoyed by and simultaneously enjoys on some level, and she also requires (or at least likes to have) Howard to help her with necessary tasks in daily life such as shopping and transport to/from fitness class and beauty clinics.

* SheWhoMustNotBeSeen: Although in "The Spoiler Alert Segmentation" she can be briefly seen in the background from behind as she shuffles around the kitchen.

* ShiksaGoddess: Howard at one point calls Penny a Shiksa Goddess. She fits the trope by being blonde, though she is green-eyed not blue-eyed.

* {{Hypocrite}}: Bernadette's description of him implies he is a very conservative Catholic (he disagrees with vatican 2... which happened in 1965.) but he later encourages her to get a pre-nuptual agreement.

** In a Season 5 episode, Penny falls in the shower and breaks her arm. She calls for Sheldon to help, because she knows the sight of her naked would literally do nothing for him. In fact, Sheldon spends more time whining about the possibility of getting injured driving than appreciating the fact that he got to enjoy Kaley Cuoco "in the altogether."

* {{Adorkable}}: Petite and cute with a squeaky voice and a love for "Literature/{{Cinderella}}".

* TheGrinch: Sheldon hates Christmas, claiming it's a knockoff of the pagan celebration of Saturnalia, bemoaning being forced to participate by his zealously religious mother as a child, etc., all to the annoyance of Leonard, who just wants some Christmas cheer because ''he'' was forced to write papers by his family on Christmas. It all comes to a head during a Christmas themed game of DungeonsAndDragons where Sheldon leaves Santa (whom they were supposed to be saving) to die, ruining the game and Christmas spirit for all involved. He declares that the real reason he hates Christmas is that Santa never granted him his wish of bringing his "Pop-Pop" (grandfather, and the only family member to encourage his interest in science) back as a kid.

* {{Adorkable}}: Petite and cute with a squeaky voice and a love for "Cinderella".

* FakeShemp: She re-appears in Season 6 giving birth to her first baby. However, considering the whole of the arc is about Sheldon's reaction to becoming an uncle, and she's only ever heard-off screen or seen with her face obscured, it's unlikely that the studio had been able to get the original actress back.

[[folder:Dr. and Mrs. Koothrappali]]

* ClosetGeek: Becomes one as the series goes on, to the point of watching the "Star Trek" movie before one of the guys and getting into an intense argument with the girls over Thor's hammer.

'''Althea:''' Unless my people were freed by Benjamin Franklin[[note]] dollar bill[[/note]] and his five twin brothers, you are wasting your time!

* HeroicSacrifice: Not a lethal one, but during a paintball war his comrades (Leonard, Howard, and Raj) have no enthusiasm due to prior events, and don't really want to fight. Sheldon proceeds to walk outside, into the open, and take several shots to motivate them into fighting, resulting in victory. [[MundaneMadeAwesome Complete with slow-motion]] and a {{Platoon}}-style [[ShoutOut "death"]].

* SuperOCD: Don't sit on his favorite couch cushion, you'll smush it out of shape. Also, the odd way he knocks. [[RunningGag "*KNOCKNOCKNOCK* Penny. *KNOCKKNOCKKNOCK* Penny. *KNOCKKNOCKKNOCK* Penny."]]

* DysfunctionalFamily:

* CuteButPsycho: She's very lovely, but has a rather disturbing side as well. She once remarked she became a dermatologist because it's a line of work where she's allowed to cut people. It could have been a morbid sense of humour, but it's a bit scary.
** Also, she has a tattoo of Sally from Nightmare Before Christmas on her shoulder blade because she likes the fact she's covered in scars and can pull her own limbs off and sew them back on.
