"Batman: The Dark Knight" The Dark Knight Returns
Batman: The Dark Knight Returns is a Batman comic book mini-series written and drawn by Frank Miller and published by DC Comics from February to June 1986. This story arc is set 20 years into the future, where Bruce Wayne is an elderly man still guilt-ridden over Jason Todd's death.
"Berserk" The Prototype
The originally published Berserk one-shot, when reprinted it has added "The Prototype" as a subtitle. Although it is similar to the original serialization that started soon after this was first published, some of the changed elements have made it non-canon. It was the first appearance of Guts and Puck, a partnership that carried over to the first Berserk serialization but was reintroduced much later in the mainline Berserk serialization.
