The hero that navigated the trials of the Minotaur is Theseus. He volunteered to enter the labyrinth and, with the help of Ariadne, he used a ball of thread to find his way back after slaying the beast. Theseus' journey symbolizes courage and ingenuity, representing the ideals of heroism in Greek mythology. His victory over the Minotaur also depicts the triumph of human intellect over the monstrous and chaotic forces of nature.
