Warning - this article contains spoilers for The Penguin

The Penguin has reached its dramatic series finale, but many will be wondering if Batman appears in the final episode.

During the series, fans will have seen Oz Cobb (Colin Farrell) launch a drug empire and criminal mastermind after he hijacked the growth and distribution of drug Bliss.

Oz's actions triggered a violent drug war in Gotham and see him betray two of the city's biggest crime families.

Sofia Falcone (Cristin Milioti) and Salvatore Maroni (Clancy Brown) teamed up to take down his drug empire and kill Oz. Yet Sal died from a heart attack and Sofia's car bomb takes out Oz's crew and operation.

Series finale 'A Great or Little Thing' saw Oz Cobb dragged away by a corrupt police officer to be interrogated and threatened by Sofia. Sofia continues to interrogate and unsettle both Oz and his mother Francis (Deirdre O’Connell) who proceeds to confront him over killing his brothers.

The Penguin was stabbed by his mother who suffered a serious stroke, but Oz managed to turn the tables in horrific and chilling fashion against Sofia.

While The Penguin has been heavily acclaimed by Batman fans, many have wondered if Batman appears in the series.

The Batman does not appear in The Penguin, but we do get a glimpse of the famous Bat-Signal in the finale.

Oz Cobb enters his luxury penthouse and it's revealed he took his mother, who is now in a vegetative state, to live.

The chilling reveal sees Francis cry in fear over her son who in turn believes she's crying over the beautiful view of Gotham.

Oz Cobb imagines dancing with his mother as they used to growing up. "Tell me you love me", he says as they embrace each other and dance around his penthouse.
