Endgame continues in Batman #36 as the Joker returns armed
with the Justice League in tow. Batman finally takes down Superman by spitting
Kryptonite gum in his face. He searches at the collapse of Akham Asylum to find
clues of the Joker. Batman is confronted by an orderly by the name of Eric
Border who locks him up and reveals himself as the Joker promising to bring
havoc to Gotham.
Eric
Border was first introduced in Batman
Annual #2 where Batman tests the cells of Arkham Asylum. Border visits the
first patient of Arkham the Anchoress who is seeking revenge of Batman for
turning the asylum into a place of punishment instead of healing. The Anchoress
plans to release every patient of Arkham. Batman remembers her from Zero Year
as the she makes him relive his nightmares of his brother Owlman and the death
of Robin his son. Border and another orderly rescues Batman.
His
second appearance is in the Joker’s
Daughter where both Eric Border and the Anchoress show up. We are given the
origin of the Joker’s Daughter and the Joker communicates with her as Eric
Border.
