Mike would likely be in pain, both physically and emotionally. Physically, he'd be trying to tend to his wounds. Emotionally, he could be feeling betrayed if he thought someone he knew was involved. He might initially be hesitant to tell Harvey or the others at the firm, not wanting to seem weak or vulnerable, but eventually he'd realize he needs their help.
After getting beat up, Mike could be very determined. He'd use this as fuel to dig deeper into whatever situation led to this. He might start to become more cautious in his investigations, but also more tenacious. He could also be a bit paranoid, looking over his shoulder more often and being more suspicious of people around him, while still trying to maintain his normal facade at work and with his friends.
He might be in shock at first. Mike could just sit there, trying to process what has happened. Then, he would probably be angry. He's not the type to just let things go, so he'd start thinking about who could be behind it and how to get revenge.
One possible reason could be that he's gotten on the wrong side of a powerful client. Maybe he uncovered some shady business deals of the client during a case, and the client decided to take revenge by having him beaten up. Another reason might be related to his past. If some of his old associates from his pre - Harvey days found out he was now working in a high - profile law firm, they could be jealous and target him.
He might be confused at first. Naruto is used to being attacked by enemies, but Karui is an ally. So he would wonder what went wrong.

Lucy getting beat up can also be a turning point for her character development. It might make her realize she needs to train harder or develop new magic skills. This could lead to her going on a training journey, which would be an interesting sub - plot in the fanfiction.
Jaune could also become angry and frustrated. He might feel that the system is unfair and that he's being wrongly punished. So he could lash out at those he believes are responsible for his expulsion, whether it's a fellow student who set him up or a teacher who didn't give him a fair hearing. In some cases, he may even try to expose the wrongdoings or secrets of the school as revenge for his expulsion.
Well, in a lot of these fanfictions, Stiles can get beat up due to his own recklessness. He might be so determined to solve a mystery or help his friends that he doesn't think about the consequences and ends up in a dangerous situation where he is outnumbered and beaten up. Also, there could be miscommunication. Maybe someone thinks he has done something wrong when he actually hasn't, and they take matters into their own hands and beat him up.
He might be extremely angry and feel a great sense of injustice. He has always seen Hogwarts as his true home, and being expelled would be like losing his family. So he would probably fight back, trying to prove his innocence and get his expulsion reversed.
