There ' s literally no room for debate here . The android saga created one and ONLY one time ring . Stated fact . Not stated . You are right about Gowasu ' s line , but it ' s not like characters in Super hasn ' t been wrong before . Also , I don ' t remember Zamasu saying anything about Trunks creating a ring , but if he did , it ' s true , he did create one . Zamasu didn ' t confirm anything related to this . The only thing you have to support it is the Gowasu line about it , nothing else . We know , however , that Cell ' s timeline is one of those rings . No definitive confirmation on the contrary , so don ' t try to pass it as a fact or a retcon . It ' s a legitimate doubt , no more than that . Oh , and they ' ve been using CELL ' s Time Machine on Super . how about that ? lolOh and the only other retcon I can remember is the Potara ' s time limit . That was not a bullshit retcon , it actually gave sense to a plothole in Z .
