Bad Ending Counterparts

 are characters in the Theory series.

The concept of a Bad Ending counterpart goes as follows: An existing Theory character's backstory is altered to be much darker, usually with tragic events. However, most Bad Ending counterparts are not necessarily villains.

Maria Tachimi
A Japanese-American criminal and a member of the Xiaoying Gang. BadEnding!Maria is wanted for 25 murders of CCOTD members and people who made her suffer as a child. She also lost her mother and father to a beating from CCOTD and an assassination courtesy of Derek respectively. She is nihilistic and ruthless, and believes that religion involves abusing people for power. Her behavior is due to the treatment she and her mother received in the past.

Sophie the Otter
An otter refugee who fled Lake Hoohaw after it, Howdydoo Island, and a few other locations were decimated due to an event called the Maverick Invasion. She now resides in a refugee camp in Lake Convalescence. Although she misses her previous life, she feels thankful for the refugee camp employees as they supplied her, her family, and her neighbors with needs.

Darren Keene
An openly gay high school student who not only lost his mother from a car crash, but his sister, Kingston from suicide as well. While bullied by his peers and abused by his father for being gay, he had a lot of friends from the gay straight alliance club and cheerleading squad to begin with, but by the time he was at the park with Chris, he was being called a "fa***t" by an angry 32-year-old man. He was punched across the face, kicked in the shin and beaten almost to death. But when Chris slapped the homophobic man in the face, he punched him in the crotch and called him an "asshole" After a horrifying near-death experience, he realized that he nearly died after the incident, but stood with Chris.

Kingston Keene
A depressed ghost of Darren's younger sister who committed suicide by shooting herself in the head after not being able to go to the girls' bathroom because she was a male despite being a female transgender. By the time she wanted to go to the girls' bathroom, another girl saw her walk into the bathroom and mistook her for a boy despite being a transgender. She was bullied by the other girls for being "a boy dressed in girl's clothes" (read: transgender). The punishments worsen for her as her father yelled at her, slapped her and stripped her naked to see if she's a boy or a girl, calling her a "tr***y" in the process. As she committed suicide by pulling a gun into her mouth, blowing her brains out, she came back as a ghost, all depressed and lonely.

As a ghost, her gunshot wound was still on the back of her head, revealing blown bits of her brain and the part of her head.
