Undyne

Undyne is one of the major characters of Undertale.
She is incredibly loud, strong, and brash. She also hates to lose, and is very stubborn. However, she does have a hidden talent of being able to play piano, which isn't expanded on in the game proper.
Proof of her inability to take an L can be found in all runs:
*In the True Pacifist Run, Frisk is tasked with taking Undyne out on a date on Papyrus's suggestion. She is clearly not pleased at this, and is quite hostile towards Frisk. She ultimately ends up burning down her own house as a result of taking her "cooking lesson" too far.
*In a neutral run, if Undyne is killed, she will refuse to die, turning Frisk's Soul green and daring Frisk to dodge more arrows. She's clearly grasping at straws, though, as the arrows get slower every time as she melts.
*In the Genocide Run, Undyne shows up far earlier than usual to take a hit for the Monster Kid; she eventually becomes "Undyne the Undying".
Undyne also appears in Deltarune as a cop. Most notably, she lacks her eyepatch here, revealing a perfectly normal eye.

An Undertale-themed Halloween special was planned for Super Smash Stadium in 2020, but was scuttled due to the very late start to Season 49. Had this come to fruition, Undyne would've appeared as a guest fighter. Mandi dressed as Undyne on other company media, though.
Undyne appears in Mario Kart: Ancient Circuit as part of the game's second DLC pack. Her home, Waterfall, also appears as a track. She is a cruiserweight, with good top speed, off-roading, and Mini-Turboing, but bad acceleration and handling.
In Tropes vs. Women in Pokémon Training, a Battle Turnpike Trainer references Undyne through her physical appearance and Pokémon choices. Also, Undyne shows up in the animation for the move Pride Parade.
