Fugo is one of the most unique characters in the Jojo's Amazing Adventuresappearing in one fight and showing the audience how terrible his stance is. The look of the Purple Haze is something that fans will remember, with this stand that foams at the mouth and is also difficult for the user to control.
The power of this stand infects anyone and anything with a terminal virus that will kill them in no time. It's such a terrifyingly powerful stance that Fugue had to be cut from the show to make future battles more interesting, which was understandable.

Beauty Diary of the future stems from its exciting premise, where players of this twisted game have a diary that can predict the future in interesting ways. The main character gets a clear diary that achieves this goal in a simple way, while Yuno's diary embodies her psychotic personality by tracking Yukiteru's movements.
For the most part, Yuno acts as a supporting character helping her partner whenever possible, though her obsession reaches dangerous levels and causes Yukiteru to try to avoid his crazy side as much as possible. She is one of the best and most iconic examples of a creepy yandere character who commits several heinous acts to prove her love to the man she is obsessed with.

For the majority Attack on TitanEren Jaeger looks like an ordinary hero who does nothing wrong. It's only after the time lapse that viewers get to see the terrifying side of his character that makes him one of the scariest and most fascinating anime characters of all time.
The look on his wild face after declaring war on Paradise Island still sends shivers down the spine of viewers to this day.

When the Black Swordsman is introduced Berserk for the first time it is easy to be frightened by his bloodthirsty behavior. The way he wields his signature sword and enjoys the act of killing the Serpent Lord makes him look insane.
However, fans won't get to see Guts in one of the greatest story arcs in anime history until after the Golden Age arc. It's easy to see why he becomes such a terrifying, bloodthirsty hero after the trauma he's endured, his mind solely focused on getting revenge on Griffith.
