* replaced Space Godzilla's role as ruler of the mutants to formal ruler due to him being deceased.
* promoted Destroyah to Ruler of the mutants
* promoted Krystalak as 2nd in command due to being (atleast in this story) the son of Space Godzila
*created personality reference for Kiryu (mecha Godzilla 3) describing him as a Godzilla accidently resurrected by the spirit possessing the mecha but without memory and seeks to find out what he once was to fully understand his powers to protect the race that brought him back to life.
Hopefully you would agree with these changes and updates.
