Fan Casting Slade Wilson in Batman: Family of Steel

Before going off to fight Superman and his family, Batman begins training himself with blade weapons such as swords and daggers, ahead of his Superior Batman suit upgrade that comes with retractable Kryptonite-infused armblades. And while he is doing this, he begins to have flashbacks to his first real adversary, Slade Wilson, better known as Deathstroke, who has been dead for decades at this point in the timeline.
