Marshall

Marshall it is confirmed

@Disneyscripts , @CM120210 , @Rocky and Marshall 22 , @Baymax6 , @Royson123456

But isn't it supposed to be Rex? Just read the page about him

It also says something about a volcanic eruption. But this will cause a big fire, it is quite possible that Marshall will be more miraculous there, as well as Rex.

@BogdanShark Rex helps out but it said in a nick article that Marshall was the main character like the one who will get a backstory

Rex is like the Liberty or the Junior Patrollers of this movie.

I say Marshall will be the main character and Rex will be the minor character in the third movie

Main Character: Marshall

Deuteragonist: Rex

Tritagonists: Ryder, Chase and Skye

Main Villain: Humdinger or an unknown villain
