my hero ultra rumble new characters

Todoroki might be another likely character. He has a complex power set and has been through a lot of emotional and physical growth. His struggle to control his two quirks could be a parallel to the control needed for Ultra Instinct. If he can master the balance within himself, it could potentially lead to the awakening of Ultra Instinct in him.

The Ultra Instinct in a fanfiction might also have an impact on the character's growth. It could be a new milestone in their hero journey. Instead of just relying on their existing quirks, they have this new ability to master. This could lead to new relationships and rivalries. Other characters might be in awe or jealous of this new power, which would create more drama and tension within the story.

Maybe it's a feature that was automatically added or a glitch. Hard to say for sure without more context.

Well, clearly Sweetballe and Rumble are the main characters. Sweetballe might be a pony with a kind heart and some special abilities or qualities. Rumble, as a pegasus, is likely to have flying skills and a personality that can either complement or contrast with Sweetballe's.

Not sure. I haven't heard about any new story in Ultra Moon recently.

Definitely Rainbow Dash. Since Scootaloo looks up to her, Rainbow Dash could offer some flying tips or be a mentor figure. Fluttershy would also be great. Her gentle nature could contrast with the more energetic Scootaloo and Rumble, and she could help them when they encounter some scared animals during their adventures.

Yes, it has some new elements and plotlines compared to previous Pokemon games.

One idea could be that the characters find a new home as a secret hideout from villains. They might use their quirks to build and customize it, making it a safe place full of unique features.

There might be a new character who is a tech - genius and uses advanced gadgets to fight crime. They don't have a traditional quirk but instead rely on their intelligence and engineering skills. This would be a fresh take on the types of characters in the story. Also, a character who has the ability to communicate with animals and enlist their help in battles could be really interesting.

I'm not entirely sure as I haven't studied it deeply, but usually there would be students like the class clown, the smart girl, and the popular boy.
