when deku uses 100 percent of his brain

The percentage of Deku's power usage changes based on a lot of factors. Like the nature of the enemy, his training progress, and the urgency of the situation. So, it's hard to give a fixed percentage.

Deku can use 100 percent in the manga, but it's usually a last resort or when he's facing an extremely powerful adversary. This power boost often has significant consequences for his body and abilities afterward.

I'm not sure of the precise percentage. Different people might have different estimates. It's best to keep up with the manga's ongoing chapters and see for yourself how far Deku's story has progressed.

It depends. Sometimes Deku can manage to use 100 percent without getting hurt if he has mastered certain techniques or has received special training. But usually, it comes with a risk of injury.

It really depends on the specific fanfiction. Sometimes Ash's Charizard has a decisive victory, while in others, the battle is more evenly matched.

Well, in many fanfictions, when Ash pits his Charizard against Tyson, it's often a high-stakes showdown. The outcome can vary based on the author's imagination and the plot they've crafted. Sometimes, it could be a close call, and other times, one might have a clear advantage depending on the circumstances and character development.

Well, he might learn about his future achievements. For example, he could find out if he becomes the greatest hero. Maybe his future self gives him some advice on how to deal with upcoming villains more effectively.

I'm not sure of the exact significance of '23 percent' in it. It could be an arbitrary number the author chose to mark a certain part of the fanfiction.

It's hard to say exactly. But often, it might involve some unexpected twists and turns. Maybe Charizard has to overcome a special challenge or use a new move to gain the upper hand against Flint's Pok茅mon.

Well, it could lead to an epic battle with lots of action and strategy.
