In fiction

Beast King Golion

Tsuyoshi is one of the five students of the Fuji Space School who returned to Earth after a space flight in 1999, only to find it in ruins after a great war. Captured by the Galra Empire, the pilots escaped to the planet Altea. Tsuyoshi's strength allowed him to bend the bars of their cell window to provide a route of escape. Once through the window, he revealed his fear of heights, though he was able to put it aside. [1]

He later meets a girl who calls herself Lisa, and learns she is from Earth and that survivors from Earth were captured and enslaved by Galra. He mentioned he had a sister, whose fate he did not know yet. [2]
