Well, perhaps Max gets hurt while trying to protect his family or a friend. He might jump in front of a dangerous attack meant for someone else. It could be a physical attack like a blast of dark magic that knocks him out cold. Or it could be a more psychological hurt.

One possible scenario could be during a battle with a supervillain. Max might be overconfident and underestimate the villain's power. The villain could then land a powerful blow that leaves Max seriously injured. For example, if the villain has some sort of energy - based attack, it could hit Max and cause internal injuries. Another scenario could be an accident during a training session with his family. Maybe they are practicing a new superpower move and something goes wrong, resulting in Max getting hurt.
