Marvel's Cloak and Dagger has confirmed two roles with ties to the original comics. The series has changed a lot, from the story's setting to a lot of what motivates the characters, but these new characters indicate the series will be keeping at least a few things that might ring some bells for the original comic's fans.
The original Cloak and Dagger characters debuted in Peter Parker: The Spectacular Spider-Man #64 in 1982. The comic features a number of differences from the TV show. Comic-wise, Tandy and Tyrone were both runaways in New York City who got their powers from an experimental heroin. The pair received their own four-issue mini-series in 1983, a year after the pair's initial comics debut. The television series takes them to New Orleans and has re-written Tandy and Tyrone to feature a much stronger connection to the MCU at large. These new character descriptions, however, indicate that Marvel's adaptation might have a closer comic connection than previously known.
According to EW, Jaime Zevallos and Emma Lahana's characters have been revealed and both have connections to the original 1983 comic. Zevallos will play "Father Delgado" who will be a school counselor and priest. He's described as constantly seeking redemption in spite of the fact that he’s not sure he deserves it. Oppressed by the collar, he leads more through words than example, as he still struggles daily with the life he has chosen. Father Delgado will be acting as a spiritual guide to Tyrone during the ordeal of discovering his powers. In the comics, Cloak and Dagger also take shelter in a church and are advised by a priest who protects them from the police.
Lahana's character, Detective Brigid O'Reilly also has a connection to the original four issue mini-series. According to her character description, Brigid O'Reilly is "accustomed to working in a man’s world, but she isn’t looking to be ‘one of the guys.’ Her New York sensibilities have hardened her from being too friendly or open, setting her apart from her Louisiana counterparts. Brigid believes in justice and doesn’t think that anyone should be above it, including other cops. Especially other cops…" In the comic, Brigid becomes a vigilante known as Mayhem who has green skin, claws and exudes a poisonous gas.
Both Lahana and Zevallos have ties to the original comics and even with the changes made to the television show, these characters could possibly fulfill their comic destinies. It remains to be seen just how they'll measure up, since the pilot featured a far more grounded and down to earth storyline with excellent social commentary.
Even if the show doesn't fulfill its comic origins or completely adapt the comic's story, it's an excellent adaptation with plenty of connections to satisfy MCU fans while opening a brand new world for them to explore. Both Zevallos and Lahana are incredible additions to a strong cast that can't be missed for any fans of the MCU, or the comic itself.
