Saiyan adopted by Thanos

When Frieza, the emperor of a certain Dragon Ball parallel universe, detonated Planet Vegeta where the Saiyans lived, a baby placed by his mother in an escape pod accidentally came to a new world; the
desolate Titans. On the star, Comrade Thanos, the director of the Universal Family Planning Commission, staring at the hazy starry sky, accidentally discovered a survivor after the demise of the Titan civilization – a baby with a tail on the back of his butt…
“The survivors of Titan, from now on, You are my son.”
ps: This is the product of my imagination after watching Women’s Federation IV with my gay friends, so everything is based on the movie universe.
