Titan

The once green and blue world turned burnt orange and brown as the upper atmosphere was ravaged by electrical storms with the broken remains of Titan society littering its surface. Even its moon was not spared, taking on a similar appearance. On a planetary scale, Titan was left eight degrees off its axis with its gravitational pull being "all over the place". Convinced that his plans could have saved his homeworld, Thanos became dedicated to wiping out half the life in the universe so as to spare other planets from sharing the fate of his own people.
