Important to note- Snowpoint Temple is completely abandoned in this(considering the events of the story, for good reason) and Regigigas is an actual colossus instead of 12' tall.
"Five humans go into Snowpoint Temple. None of them are seen again."

Part two! :D This person got absolute cop energy, lmao. Well, they are a cop. This is why Registeel was next, I figured it would be more appropriate for a cop.
