When Robin becomes Red X, the Titans' reactions would vary. Starfire might be the most understanding, trying to reach out to him. Beast Boy would probably be scared and make jokes to hide his fear. Cyborg would be all about analyzing the situation, trying to figure out if Robin can be trusted. Robin, on the other hand, would feel isolated from his team. He'd have to work hard to prove that he's still on their side, and that the Red X powers are just a tool he's using for the right reasons. This would lead to a lot of tension and some heart - to - heart conversations as they all try to adjust to the new situation.
Well, at first, the Titans would be very suspicious. Robin has taken on the guise of a former enemy. They would keep their distance and watch his every move. But as time goes on, if Robin uses the Red X powers for good, they might start to see that he's still the same person deep down. However, there would always be a bit of uneasiness, like they're waiting for him to snap and turn back into a villain - like Red X.
In the 'Fire Emblem Robin Becomes a Dragon' fanfiction, his personality change could be complex. At first, he may be confused by the new emotions and instincts that come with being a dragon.

His sense of justice, which was present in his human form, could be magnified. He might be more likely to take on powerful enemies without hesitation, seeing it as his duty as a powerful dragon. And yet, he may also have moments of vulnerability when he misses his human form and the relationships he had in that state, which could add depth to his character in the fanfiction.
If Beast Boy becomes Slade's apprentice, some of the Titans might try to reach out to him secretly. They would hope to bring him back to the good side.

Well, Naruto's newfound maturity might lead to a more understanding relationship with Sasuke. He could approach Sasuke with more wisdom and less impulsiveness. Maybe he'd be able to better see Sasuke's pain and reasons for his actions, and Sasuke might start to respect Naruto's growth more, leading to a less adversarial and more collaborative relationship between them.
In this fanfiction scenario, Sasuke might be jealous of Naruto's new power at first. He has always been competitive with Naruto, and seeing Naruto become something so powerful as the Kyuubi could trigger that jealousy. However, when they face a common enemy together, Sasuke sees that Naruto is struggling to control the Kyuubi's power and needs his help. This could lead to a new level of understanding and friendship between them, as they work together to help Naruto master his new form.
Their relationship could become more of a partnership. With Naruto as Hokage, Sasuke might be more willing to work within the village's framework. They would still have their friendly rivalry, but it would be more focused on making the village better.
At first, Elena might be shocked and a bit scared when she finds out. Their relationship could become strained as she has to adjust to the idea of her brother being a vampire.

His relationship with Sasuke might become more competitive. Since they are both aiming for higher levels of ninja skills, they would constantly push each other. With Sakura, Naruto might be more respected as he has achieved the Chunin rank, and she could see him in a new light.
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.
Their relationship could transform into a more mentor - mentee dynamic. Percy, with his godly knowledge and powers, could start guiding Annabeth in a different way.
