Star trek, Family guy, doctor who, mlk cartoon, x-men, butterfly effect. Back to future 3 Subverted. Flashpoint.
- Sonic the Comic has a unique example of an antagonist fixing a wrong in the past to advance their agendas.The Brotherhood of Metallix traveled back in time and prevented the Freak Lab Accident that transformed kind veterinarian Ovi Kintobor into the evil Ivo Robotnik. As the doctor played an integral role aiding Sonic and the Freedom Fighters in opposing the faction, this created a Bad Future where the Brotherhood conquered Mobius and renamed it "Planet Metallix". Sonic then went back and Set Wrong What Was Once Made Right, leaving us with the disturbing knowledge that the hero is responsible for unleashing a great evil in the series, even if it was to prevent a greater evil from taking place.
- Discussed, but ultimately averted in Miss Kobayashi's Dragon Maid. Lucoa offers to rewind time for Ilulu to before her Heel–Face Turn so she can undo her attempted destruction of the city and ease her guilt, but Ilulu turns down her offer on the grounds that it would also undo everything that Kobayashi had done for her.
