It was later revealed that Barry Allen had Zatanna tamper with the mind of supervillain the Top, turning him into a hero (the Top had gone on a murderous rampage and Allen believed this was the only way to stop him from causing more harm). As a hero, the Top went insane over the guilt of his earlier deeds. After Allen had died, Wally received a letter from Barry asking him to restore Top's mind if he ever returned. After Wally had Zatanna restore the Top's mind, the Top revealed that when he had been a hero he had attempted to reprogram many of the other Rogues into heroes as well, including the Pied Piper.
