A monster was created by the dropping of the atomic bomb. Godzilla harbored no ill will to the humans population for creating him. It was thanks to a Melowy named Cleo. Cleo found Godzilla and Godzilla fell in love with the mare. Cleo used his love for him to make him promise not to attack any human city unless another MUTO attack it. Godzilla agreed to this deal and they married and laid an egg not soon after their marriage. However, due to his size, he is easily detected by sonar. This cause the human army to form different plans to kill him. No matter what they tried, Godzilla managed to survive. In order to protect the egg, Cleo used her special magic to travel to Equestria and placed the egg in Equestria before heading back to the human world. The Humans managed to track the egg to Equestria but is unable to destroy the egg due to the fact they did not have magic. This quickly changed when a Admiral who owns secret Unicorns used the Unicorns to build a ship that was capable of inter-dimension travel. This ship was heavily armed and needs only one person to control. The ship has large rapid-fire cannons, AA guns and is able to launch a total 10 fighters into the air (Using multiple catapults located on its sides)
It was sent to Equestria to hunt down the egg and destroy it. Unfortunately for the humans, the egg hatched and the creature swam to shore. The Creature found its way to an orphanage and got the attentsion of its staff. The staff of the orphanage adopted the creature and named her 'Little Spark' (aka Sparky) due to her small size and the fact that her spikes on her back glows blue when she is sleeping.
