Due to a number of reasons, when these individuals use their powers, they incur great risks.
With great powers come great responsibilities, but sometimes, they may be more than what these characters bargain for. There are so many main characters with mind-blowing powers that can destroy the most powerful villain, thus allowing them to save their world.
In order to reach their full potential, they have to undergo brutal and necessary training, and most times, it is more than what their human body can handle, therefore leading to complications. However, their will is much stronger, and even though their power can and does destroy their body, they never back down or give up; instead, they find a way to accustom their body to it. 7 Gray Fullbuster (Iced Shell)
