Well, some might be really amazed. They could see a new side of Deku that they never knew before. His singing might show a different level of confidence or a hidden talent, so they would probably cheer him on.
Bakugo would likely be furious. He'd feel betrayed and would probably be the first to attack Deku, yelling at him about how he's thrown away everything they've worked for. Uraraka might be more empathetic. She'd try to understand what drove Deku to become a villain and hope there's a way to bring him back to the side of good.
In 'Class 1 - A's AUs Adventure', they not only watch different AUs but also get to interact with their alternate selves in a very unique way. The story is full of humor and some really cool fight scenes that are different from the original series because of the AU elements.
You can start by looking on Archive of Our Own (AO3). It has a large collection of fanfictions, and if you search for 'bnha class 1a watches aus', you're likely to find many relevant stories. AO3 is known for its wide variety of fan - created content.
Bad Cat Search was an excellent novel search tool that could be used on a variety of platforms, including PC, mobile phones, and tablets. As for whether there is an Apple version of Bad Cat Search, I don't have any relevant information in my knowledge at the moment. However, under normal circumstances, the software on the Apple platform is usually only applicable to Apple devices. Therefore, using Bad Cat Search on Apple devices may require the use of other software or plug-ins. If you have any questions about the bad cat searching for the Apple version, feel free to ask me.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
He might cry a lot. Deku is very emotional, and being cheated on would be a very painful experience for him. He could also get angry, which is rare for him, but this situation would be so unjust that he might not be able to hold it in. He'd probably start to question his self - worth too, thinking that there was something wrong with him that made his partner cheat.
Deku might be initially shocked. He's used to Bakugou's aggression, but an actual injury is different. He could be in pain and disbelief at first. Then, he might try to downplay it, especially if he doesn't want to cause trouble for Bakugou, because Deku is generally a very forgiving character.
I think Uraraka would be very excited. She has always been a big supporter of Deku. Meeting Future Deku would give her a chance to see how far he has come, and she might also get some inspiration for her own hero journey. Plus, she's a friendly and emotional character, so she'd likely be thrilled at the opportunity.
