So, in honor of that, here are some beloved marvel and DC comic characters that will be gathering to drink green beer and sing the Unicorn Song in the local pub tonight.

How can any list not have Shamrock on it. this Marvel character Shamrock first appeared in Marvel Super-Heroes: Contest of Champions #1. She would later go on to appear in several books, including: The Incredible Hulk Vol. 2 #279, Rom #65, Marvel Comics Presents #24, Alpha Flight #108, Guardians of the Galaxy Annual #3 and #4, Excalibur #108 , and Marvel Monsters: From the Files of Ulysses Bloodstone and the Monster Hunters. She even had her own entry in the All-New Official Handbook of the Marvel Universe A-Z #9. What was her power, why the Luck of the Irish, of course. More specifically she possessed by the souls of thousands of victims of wars who manifest themselves as poltergeists which affect probability within a 20-foot radius of her, altering situations so that she is given an advantage.
Sham,rock recently appeared in a story written by Kathryn Immonen and illustrated by Colleen Coover in Girl Comics #2. If you haven't read this story, The years have not been kind to poor Shamrock.

Cassidy is a vampire featured in the Vertigo series Preacher. He is the best friend of Jesse Custer and Tulip O'Hare. He charms just about everyone with his exuberant attitude, rapacious wit, his honest vampirism, and his love of life overall. But, Cassidy is really has two personas: one a loyal, fun-loving, well-meaning Irish rogue, and one a desperate, selfish, weak-willed addict with a violent streak.

Unrelated to their Distinguished Competition character with the same name, the dysfunctional family of Irish mutants that make up this entry have been around the Marvel Universe for quite some time.
The now deceased Banshee (Sean Cassidy) was an Irish mutant and member of the X-Men who possessed a "sonic scream," capable of harming enemies’ auditory systems and causing physical vibrations. A former Interpol agent and NYPD officer, Banshee was always a decade older than most of the X-Men and had only a relatively short tenure as a full-time X-Man. He was, however, a mentor of the 1990s-era junior team Generation X. He was killed by Vulcan.
Like her father, the X-Men's Banshee, Siryn, (Theresa Cassidy) also has a "sonic scream." Siryn was raised by Banshee’s cousin and arch-nemesis Black Tom Cassidy without Banshee's knowledge. By her early teens, she left Black Tom and joined the X-Men offshoots X-Force and X-Factor. She also has a questionable relationship with Deadpool.
Black Tom Cassidy on the other hand, doesn’t have a scream, but instead can manipulate, bond with and project energy through plant life. He was the black sheep of a prominent Irish family. When Tom secretly raised Siryn he conscripted her into his criminal gang. Black Tom was also a longtime partner of the super-strong villain Juggernaut, until Juggernaut's recent reformation.
These guys are so Irish that they have Leprechauns living in their castle as can be seen from the Nightcrawler image from Uncanny X-men 103.

The villainess known as the Silver Banshee first appeared in Action Comics #595. In that story, Siobhan McDougal was the first-born child of Garrett McDougal, the patriarch of an old Gaelic clan that has occupied an island midway between Scotland and Ireland for a thousand generations. On that island is Castle Broen, where first-born McDougals undergo a ritual to prove themselves worthy to lead the clan. When Siobhan was young, she traveled the world, only returning to Castle Broen when she heard of her father's death. Her uncle Seamus determined that no woman would lead the clan and intended her brother Bevan to become the new patriarch. She went ahead with the family ritual by herself, which involved calling on supernatural forces for power. She was interrupted by Bevan, and the distraction proved disastrous as she was dragged away into an infernal netherworld. An entity called "the Crone" granted her powers and the ability to return to Earth as the Silver Banshee, but demanded payment in the form of an occult book that belonged to her father. She found that her father's book collection had been shipped off for sale in the United States. Her quest brought her to Metropolis. Killing anyone that stood in the way of her search attracted the attention of Superman. Unable to defeat Superman, she chose to retreat and continue her mission at a later date.
Most Recently, Silver Banshee faced off against Supergirl.


Irish Catholic Matt Murdock is like the JFK of the Marvel Universe. As a kid, living in the Hell's Kitchen neighborhood of New York City, was blinded by a radioactive substance, which blinds him and give him super enhanced sense. After his father is later killed by gangsters, he becomes Daredevil. Then he goes insane a few times, changes his costumes, sleeps around a lot (a lot of his “partners” die horrifically), changes his costume, gets redemption, goes crazy some more, and then seeks redemption again.


Tommy Monaghan is an ex-Marine Gulf War veteran turned contract killer from the Cauldron, a lower-class Irish district of Gotham City. After gaining super powers, Monaghan decides to specialize in killing metahumans and supernatural threats, targets typically shunned by conventional contract killers as too dangerous or too expensive. Despite his powers, Monaghan relies most on his creativity, improvisational abilities, and impressive gunfighting skills to take down a majority of his targets. This specialty line of work gives him an edge over his competition, but also leads him to encountering a number of eclectic characters including demons, zombies, dinosaurs, gods, superheroes and supervillains, as well as more conventional, realistic characters such as CIA agents, the SAS and the Mafia.

The All-Star Batman and Robin version of Black Canary is an immigrant from County Monaghan, Ireland. In the series, written by Frank Milles and drawn by Jim Lee, Black Canary is an unnamed bartender in a seedy gin joint called "Black Canary". Her costume is actually just a uniform she wore for her job. She is offended by the lewd flirtation of the bar's male patrons. Deciding that she has finally had enough, Black Canary beats up all of the male patrons in the bar. When her boss asks her what got into her, she simply replies "Batman," assaults him, and then leaves the scene on a motorcycle stolen from one of the men she has just battered. She later makes out with Batman, while Batgirl jumps around and yells a lot of stuff that was incorrectly censored with black boxes, which caused the initial run of the book to get pulped.
