I haven’t seen Lycoris Recoil, but I’m not sure I’d call the other three power fantasies. Sure these main characters are OP, but they all have goals or wishes that remain out-of-reach for them despite that. Mob’s goal isn’t to smash other dudes with his power. He just wants to be able to run better than an old lady and confess to the girl he loves. Likewise, One-Punch Man avoids it because the main character’s dream is to have an engaging fight and his overwhelming strength doesn’t help him with that at all. Frieren can kill demons all day but it won’t bring her dead friend back to life.
