Kaiju Planet

Overview
Kaiju Planet is a theme park on a distant planet created by a group of scientst, who genetically modified animals to be gigantic.

History
In the early 2000's, a group of scientist discovered a panet unlike any other, it was similar to Earth back in the Late Triassic yet looked completely alien. They spent 3 decades studying this planet and somehow kept it secret until they could fully understand this planet that time forgot.

Around the same time, another group of scientist in Japan were genetically modifying animals to be kaiju sized, after many failures they finally made the world's first kaiju: Aswang. It unfourtanately killed off its creators and attempted to escape but was defeated by the failed experiments and was put into suspended animation by the JSDF. Eventually in 2030, the scientist finally explored the planet and made a space traveling organization that later became Mech-Tech, then created Kaiju Planet, the largest theme park in the known universe. They moved Aswang and the other failed experiements into an underground laboratory on the planet.

The Aswang Incient
Many years after  Kaiju Planet was opened, Mech-Tech decided to attempt to make their own kaiju incase there would be a war on Earth or if something comes to the planet. Eventually, they came up with the idea of replicating Aswang but all they had to do was get his DNA, while extracting it, Aswang woke up and destroyed the lab, releasing itself onto Kaiju Planet. Mech-Tech attempted to stop Aswang by using many weapons against it, including mobile sentury turrents and Mechas that they created incase one of the kaiju break out of their exhibit but unfortunately nothing stopped him, Aswang unleashed all the kaiju in Kaiju Planet along with the failed experiments and overthrown the theme park.
