The Teen Titans would react with a combination of fear and courage. Starfire, being from another planet, might have some knowledge about the invaders which could be useful. But she'd also be worried about her new home, Earth. Cyborg would probably be excited to take on the new technology of the aliens, seeing it as a challenge to improve his own. Raven, on the other hand, would be more cautious and try to sense any dark motives behind the invasion.
The Teen Titans came into existence as a group of young superheroes. Each member had their own origin story. For example, Robin was originally Batman's sidekick. He brought his skills and determination to the Teen Titans. Starfire came from another planet, Tamaran, and she had superhuman strength and the ability to fly. Cyborg was a result of a scientific experiment gone wrong in a way, which gave him his cybernetic enhancements. Beast Boy could transform into different animals due to an experiment. Raven had her own mysterious background related to her demonic father. Together, they formed the Teen Titans to fight crime and protect the world.
The formation of the Teen Titans had several important events. Robin, having grown as Batman's sidekick, felt the need to step out on his own and lead a team of young heroes. This was a crucial starting point. Then, Starfire's journey to Earth was a major event. She crashed on Earth and her powers and alien nature attracted the attention of others who would become Titans. Cyborg, who was dealing with his new cybernetic body, saw an opportunity to be part of something bigger. Beast Boy, who had always been different because of his shape - shifting abilities, found a group that accepted him. Raven, with her complex powers and background, also joined, and together these events led to the formation of the Teen Titans.
It adds variety. There are so many different ways to interpret the Teen Titans characters, and this fanfic offers one more unique take. It gives fans who are interested in this particular concept (futa Beast Girl) something new to enjoy.
Naruto could fit in by sharing his knowledge of the ninja world. This could include things like how to make different types of ninja tools or how to perform certain stealth techniques. In return, the Teen Titans could teach him about teamwork in a different way than he's used to in Konoha. His unique abilities like summoning animals could also be a huge asset when they are up against tough enemies.
Raven might be a bit aloof at first, but she would eventually try to use her magic to help him. She has a deep understanding of emotions and powers, so she would see it as her responsibility. Starfire would be overly concerned and would probably try to cook him all kinds of strange but nutritious meals to help him through it. Cyborg would likely try to analyze him with his tech, thinking there's some sort of mechanical or biological malfunction that he can fix.
Beast Boy would be quite distraught. He might initially feel a bit helpless, but then he'd start thinking of creative ways to find Robin. He could transform into various animals to search for clues or to sneak into Red X's lair. His sense of humor might also help to keep the team's spirits up during the search, even though they're all worried about Robin.
Cinderstar is likely a character created specifically for the Teen Titans fanfic. She could be a new hero or villain in the fan - created world of the Teen Titans.
