Francis Castle (Earth-3064)

"One more criminal dead, and this city is a safer place. I did more in one night than you ever accomplished in what, 8 years? I am the true dark knight."

- - The Punisher to Batman Francis "Frank" Castle is a former FBI agent who had his family killed by Sal Maroni because of Castle having murdered Falcone's son, Mario. Vowing revenge after the massacre of his family on a family party, Castle became the hardened vigilante Punisher, who killed any criminals standing on his way, which made him one of Batman's most phylosofically cunning adversaries, as Bruce has to protect criminals from Frank's bloodlust.
