It is common to find in animes some characters that are or have been affected by amnesia, generally retrograde or dissociative, for a various length of time. Those ones are frequently praised by the audience as there is always some kind of big mysteries hiding in their past, often tragic.
Personally I love those kind of characters as it makes my imagination run wild imagining what could have happen during that unknown period of their life.
But the amnesia doesn’t always appear in this way, from times to times it affects the story by altering drastically or not the behaviour of the protagonist.
Here are 10 memorable characters who lost their memories:
1. Touma Kamijou from “Toaru Majutsu no Index”
2. Lucy from “Elfen Lied"
3. Vash the Stampede from “Trigun”
