Nothing and no one has said that Ophis and Great Red are needed together to destroy Trihexa. If anything, the opposite has been suggested, since what is feared is a clash of Trihexa and Great Red because of their comparable powers. This wouldn't be an issue or kept in mind if Trihexa was equal to Great Red and Ophis put together. Therefore, the story itself proves that Trihexa is only as strong as Great Red or Ophis (full power) individually, at most.
