Legendary Hero (Dragon Ball Z/Super x Tate no Yuusha)

Broly is a very peculiar person because it is the first time that a Legendary or Mutant Saiyan stopped destroying everything he saw; for a special reason, but one day (while he was training to become stronger) he is unexpectedly summoned without his consent to a rather strange world with laws that border almost fantasy. (Warning: Broly Fusion. Changed personality).
