Demencia is a character from the Mexican web series Villainous. She has competed in all Ms. /co/ tournaments, reaching round 3 the first two years, and round 2 in suceeding years. She was also the consecutive #43 seed the first two years. She notably lost to Hekapoo by one vote in 2020, the same opponent she lost to the year prior with the same #11 seed. In 2021 she beat notable contestant Kim Pine in Round 1, but had to face heavy hitter and former semi-finalist Shego in the second, suffering a heavy defeat, but in the process having an indirect revenge on Hekapoo by outlasting her one round.
By this point anon's noted how Demencia had made every tournament despite her show not having even premiered yet. Her show did eventually premier in 2022, but did not seem to have an especial impact on her performance. She still qualified (for now on under her English name Dementia), but was eliminated in the 2nd round by Coraline. In 2023 she continued her yearly appearances, losing round 1 to Tinker Bell though remaining in the increasingly small group of characters to appear every year.
