However, there are a select few who have actually managed to attain immortality. There are different ways of gaining immortality, and most of them come at a great cost. These immortal characters have a distinct advantage in battles, as their inability to die makes them immune to attacks from their opponents.
Updated May 11, 2022, by Suzail Ahmad: The world of anime is ever-expanding and every week a new anime is released with ridiculously powerful characters. These characters bring a great deal of excitement to viewers’ screens, which is a big reason for the success of any anime series. Many of these characters are bestowed with true immortality or pseudo-immortality, both of which are extremely powerful. As a result, anime characters who possess either of these two forms of immortality really should not be messed with.
14 All For One - My Hero Academia

When Yuji consumed one of his fingers, it became clear why Sukuna was feared in the past. Sukuna’s powers are directly linked to the number of fingers that are consumed by an individual. The more fingers that he consumes, the easier it becomes for him to withstand more powerful attacks.
