It's funny, around 2001 I was making this game with RPG Maker named Chrono Galaxy. A silly crossover RPG where all dimensions melt in one galaxy and you could space-travel with Epoch and recruit Link or Kirby.
The point was, I had made Reptite Crono and Reptite Magus, Reptite Zeal and others on a Reptite planet. Based on that CT ending.
I also like the theory about Leah coming from the Reptite Dimension, consider it like this:
- Chronopolis is pulled back in time due to experiment phail.
- The Planet goes omgosh I should do something.
- The Planet sends Leah to Serge's era in order to help his cause.
- Reptite Dimension is created from Leah/Ayla absence, allowing Reptites to get in caves instead of humans and survive. If Ayla was there, the humans would take the caves and leave Reptites out in the cold.
- Reptites develop into Dragonians, and Dinopolis is pulled back to Serge's dimension.
How does that sound?
