As it turns out only one had survived the extinction through the deep trenches of the ocean and that being was you aka Titanosaurus. A giant sea dinosaur that peacefully slept for a hundred years until you were discovered by a mad marine biologist who captured and experimented on you to be used as a mind controlling weapon against humanity until a certain legendary Kaiju stopped and freed you from control. Knowing that there will be others looking for you, so you made your escape and swam away to find a new home to hide in. After traveling so far you ended up in a city called Metropolis and you decided to make this your new home.
