Cloak and Dagger are a pair of superheroes in the Marvel Universe. Originally appearing in Spectacular Spider-Man #64 (March, 1982), they were created by Bill Mantlo and Ed Hannigan. While never having been A-listers along the lines of The Mighty Thor or Iron Man, with their issues often getting canceled after a very short period, they have a distinct cult following, which is somewhat tinted by nostalgia due to their 1980s background. They often team-up with other superheroes, namely Spider-Man, who is a good friend. Before the series was cancelled, they also had a brief membership in the New Warriors. Their most memorable recent appearances were in Runaways and Dark X-men.Tandy Bowen and Tyrone Johnson, a pair of teenage runaways, are experimented on by the mob, who are trying to create a new drug substitute for heroin. It proves fatal to all they test it on but the pair, who gain superpowers from the event. Tandy can throw daggers of light, which can also purge unhealthy chemicals from a target as well, while Tyrone's powers were originally to suck people into a dark dimension where he would strip them of their light. Together, they battle the drug trade while trying to balance out normal lives.In 2013, Cloak and Dagger were made part of the Ultimate Marvel Universe when they debuted in Ultimate Comics Spider-Man with a new origin story. In this world, Ty Johnson and Tandy Bowen were the student council presidents of rival schools who, en route to Prom together, were involved in a vehicular accident, and then secretly taken by the Roxxon Corporation and pumped full of Dark Matter, resulting in the explosive awakening of their powers.

Cloak and Dagger Vol. 4 (May, 2010). A one-shot.
Spider-Island: Cloak and Dagger (October-December, 2011). 3 issues.
Dark Is Not Evil: Cloak, for all his broodiness, withdrawn nature and overall intimidating manner, is really a nice guy once people get to know him.
Living Shadow: Cloak's "body" is literally made up of one. Made even more explicit in the Ultimate Universe, where you can see black swirling mists emanating from the edges of Cloak's form.
Super Cute Super Powers: Dagger can fling "light-knives" at foes, which can pierce armor and act like scalpels to "cut" the wickedness like tumors from her targets. These light-knife attacks appear wrenching and painful on impact, however.
As the Good Book Says: Their series started off each splash page with a paraphrased quote above the title. Psalm 139:12-14. "The darkness and light are both alike... I am fearfully and wonderfully made."
Adults Are Useless: Subverted in their series. With the exception of Tandy's stepfather, who is more Played for Laughs than anything else, most of the adults who help the duo are capable and responsible. It comes full circle in Runaways when they are the only ones who get anywhere close to helping the teens.
Beauty Equals Goodness: It's mentioned by almost every male character who lays eyes on Dagger that she looks like an angel.
The Big Rotten Apple: Since they were created in the early '80s and focused on combating drugs and prostitution, C&D spent a lot of time in this milieu. It's lampshaded in their Spider-Island miniseries, where the characters talk about how different New York is now and the old Holy Ghost Church is bulldozed for urban renewal.
Depending on the Artist: While Tandy gets drawn relatively consistently, the same can't be said for her partner. Cloak gets drawn looking like anything from a normal guy with his face in the shadows to a ghoulish monster that doesn't even look human anymore.
Development Hell: Where the supposed movie or TV show Marvel is trying to create seems to be stuck in.
Did You Just Punch Out Cthulhu?: According to vol. 2 of the title (1985-1987) and related issues, all persons absorbed through Cloak's darkness are send to a demon by the name of Predator. It first uses nightmarish illusions to cause victims to despair, then feeds on their lifeforce. It is immortal and seemingly all-powerful in its home dimension. Until #10 of the series, when Cloak sends Doctor Doom to the Predator. He fails to despair, quickly overpowers the demon, and leaves it in severe pain. He then simply steps out of the darkness back into the real world, something which typically required outside assistance for prisoners of the Darkforce.
Evil Costume Switch: When Tandy gets brainwashed evil, her entire costume, even the ring around her eye, turns black.
Fanservice: There's some for both genders here. Tandy has a skin-tight costume with most of her navel and the sides of her breasts exposed. Tyrone ends up naked when he's depowered, which tends to happen a lot.
Flip Flop of God: It has been stated at different times that the pair were mutants whose powers that hadn't developed yet got warped by the drug or that they are just mutates whose powers specifically came from the drug.
Hair of Gold, Heart of Gold: Especially in the duo's early days, blonde Dagger was the sweet and friendly counterpart to Cloak's harsher outlook.
Horror Hunger: Cloak (or the being living inside his cloak, depending) has this for the "light" of human lives.
Light 'em Up: Tandy's daggers are composed of pure light that can purge drug addictions.
Like Brother and Sister: This is the best description of their relationship. They truly love each other but usually, it's specifically stated to be platonic.
Most Common Superpower: Dagger fulfills this trope, but she's surprisingly better proportioned than some of the superheroines in Marvel.
Temporary Blindness: Dagger has a lengthy case of it which lasts over a year, creating one of the more interesting story arcs. She learns to readjust to being both a blind person and superhero, and once she is cured, her spatial awareness is left heightened.
Salt and Pepper: Somewhat inverted, as Cloak is withdrawn and straitlaced, with Dagger being the one to get him out of his shell.
Shown Their Work: The writers did a lot of research when Dagger was blind, using many techniques utilized by the blind in real life, and even printed the names of books and people they had interviewed in their letters page.
Superpowerful Genetics: Dagger seems to have partly inherited her powers from her biological father the Lord of Light/Nathan Tyler. He had the power to drain the life-force of other beings and manifest it as a blinding light.
Super Serum: They got their powers from being injected with drugs. Not the most family-friendly backstory, as was lampshaded in Runaways.
Time Marches On: Looking at their old 80s issues, certain aspects of New York City like Times Square being a den of drugs and porn, seems almost laughable when comparing it to how it is today.
Vague Age: Orginally averted, as Tandy and Tyrone were said to be 16 and 17 years old, respectively, and were around the age of the New Mutants. Now, it's a little harder to pin down exactly how old they are supposed to be, but a safe estimate is at least somewhere in their 20s.
What Could Have Been: It was announced they were going to have a five part mini-series written by Valerie D'Orazio. It never materialized and instead they joined Dark X-men.
What Happened to the Mouse?: A 1991 storyline introduced Cloak's twin sister, Anna Johnson. She was a vagrant with Danger Prone tendencies, which led to her having nasty encounters with neo-nazis, demons, and arsonists. As of her last appearance, later that year, she was scared and hiding somewhere in New York City. Cloak was contacting a search for her in an effort to reconnect with his last living relative. Cloak and Dagger's title was cancelled at about this time and this plotline was never resolved.
Will They or Won't They?: It's been 30 years since the pair first appeared and they still haven't fully rectified their UST. Though, to be fair, Cloak's body seems to have Barbie Doll Anatomy when his powers are active, and when they aren't he and Tandy generally have more pressing matters on their mind.
Tropes for Ultimate Cloak and Dagger
Destination Defenestration: In her first fight with Bombshell, Dagger is hurled through the front window of Miles Morales' family's restaurant.
Glowing Eyes of Doom: Dagger's eyes glow with bright light when she's emotionally unsteady, such as when she was demanding Cloak release Bombshell from his folds, lest he kill her.
Horror Hunger: Seemingly averted in the Ultimate incarnation of Cloak. He kept Bombshell in the folds of his cloak for a few minutes, and she emerged without the ill effects of Cloak's Earth 616 counterpart. We don't know enough, yet, though, as Dagger did seem to feel that Cloak keeping Bombshell in there for a prolonged length was dangerous to their adversary.
Mythology Gag: The driver of Ty and Tandy's limo was Simon Marshall, the man who, in the original Marvel Universe, created the synthetic drug that gave them their powers.
On a Meta level, once more Cloak and Dagger are making their debut in the pages of a Spider-Man comic.
Pragmatic Adaptation: Some elements have been clearly changed to avoid Unfortunate Implications. The duo's powers no longer come from drugs, and instead from Dark Matter. Also, in the original universe, Ty suffered from a speech impediment and a learning disability. In this world, he's a student council president and the assistant manager of a fast food restaurant.
Thou Shall Not Kill: Dagger reminds Cloak that they're not killers when he tries holding Bombshell in his cloak for an extended period of time.
UST: Notable for being averted. In this world, Ty and Tandy were dating for six months before the car accident rendered them comatose. Tandy had even just finished telling Ty that if he asked her to marry him at that moment, she'd have said "yes".
