Spoilers for 'The Penguin' follow.
"The Batman" ended by suggesting that Oz Cobb/Penguin (Colin Farrell) would be stepping into the shoes of his late boss, Carmine Falcone. The series opens with Oz meeting with Falcone's princeling, Alberto, and killing him, leading to a series of events that complicates his rise to power.
Jason Todd's DC Comics origin as Robin, explained
Jason Todd was introduced as a new Robin in the comic book world in 1983, originally with a backstory mirroring that of the first Robin, Dick Grayson, but was later revised to reflect a more complex character.
