Credit goes to GodzillaZero-Ones Hebimizu blog post for the inspiration.

Origins
A meetup between a Great White and a Saltwater Crocodile resulted in a fight to the death between the two. They came to a volcano, which exploded and destroyed itself, knocking both out. They woke up just to somehow be merged by a massive nuclear bomb testing, where the creature went to dormancy after migrating to Mauna Loa.
