Daniel "Terrible" Turpin is a character published by DC Comics. He first appeared as Brooklyn (due to him being born in New York City) in Detective Comics #64 (June 1942), and first appeared as Dan Turpin in New Gods #5 (November 1971).
Due to a recent retcon, Dan Turpin was made the adult version of Jack Kirby's Golden Age "kid-gang" character Brooklyn, of the Boy Commandos.
In Turpin's first appearance he is one of the few citizens of Metropolis aware that a secretive war is taking place in the city between super-powered beings. When this war turns violent, Turpin's boss tries to take him off the case, but he is ignored. Dan leads the fight against the rampaging Kalibak, using the energy of the entire city to assist Lightray and Orion in defeating him. Turpin suffers multiple injuries but survives.
He keeps his job and becomes Lieutenant Inspector of the Metropolis Special Crimes Unit. In the third Superboy series, Dan Turpin is sent to Hawaii to investigate whether or not they needed a Special Crimes Unit of their own. While initially skeptical, a visit from the violent Darkseid faction, the Female Furies convinces Dan that the islands need an SCU. In current Superman titles, Turpin is extremely loyal to Inspector Sawyer, before her transfer to Gotham City. His romantic feelings for her fall apart when he learns she is a lesbian. Turpin has a daughter named Maisie.
He has spent a long time fighting threats in Metropolis; such as the rampaging group of mutants called the 'Underworlders'.
Dan Turpin returns in Final Crisis #1 (May 2008). He had been called back from retirement to investigate the case of several missing kids; this evolves into investigating the death of the New God Orion. Orion passes on several cryptic phrases to Turpin, telling him that "He is in you all!" before finally passing away.
In the second issue, he follows clues given to him by Renee Montoya and The Mad Hatter, investigating The Dark Side Club and journeying to the devastated city of Blüdhaven. There he meets up with Reverend Good, and begins to realize that "there's someone in my head."
In the fourth issue, Turpin, after much inner struggle, is turned into the new host body for Darkseid; Darkseid later reveals that he selected Turpin rather than Batman as a host because Batman would have resisted longer than he wished, while Turpin struggled just enough to make his victory sweeter.
In the sixth issue, Batman uses a gun loaded with a Radion bullet, which is poisonous to the New Gods, to shoot Darkseid in the shoulder. Barry Allen and Wally West, managing to outrun the Black Racer—currently after Barry—so that it takes the currently-weakened Darkseid during a confrontation with Superman. After Darkseid is claimed by the Black Racer, Turpin is reverted back to normal and regains control over his body, breathing "In us... in all of us..." in apparent recognition of the meaning of Orion's last words.
In Superman: The Dark Side, an alternate reality in which Superman's rocket crashed down on Apokolips and the infant Superman was raised by Darkseid, Turpin is a member of the Metropolis Special Crimes Unit, who greets Superman when he arrives on Earth from Apokolips.
In Superman's Metropolis, an alternate reality in which Clarc Kent-son is the adopted son of Jon-Kent and Marta, the founders of Metropolis, and rules the dystopian city, Turpin was among the lower working class who was part of Lois's workers' revolution.
In Elseworld's Finest, Inspector Turpin is a Metropolis detective who frequently comes into contact with reporter Clark Kent.
Turpin appears in the Smallville: Season Eleven comic-book continuation of Smallville.In the 1990s Superman: The Animated Series television show, Turpin was modeled on Jack Kirby and voiced by Joseph Bologna.
Dan Turpin has an uncredited cameo in the 2013 direct-to-video film Superman: Unbound. He appears as one of the police officers attempting to save Lois Lane from being kidnapped by terrorists. In this version, he looks very similar to his Superman: The Animated Series counterpart.
