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.
