- In this au the monsters have gaster blasters forms (both feral and anthro ) along with their monster forms but they where not born gaster blasters though so you know.
- Monsters in this au can suffer some pain and mental damage abit when they change into their gaster blaster form and all since it painful to change into and they don't always enjoy the change that is for sure.
- Depending on their magic can depend on how they look when in gaster blaster form sometimes as well too.
( still working out more for this au so there will be more things over time added for it and all )
