Siryn

Origin

While Sean Cassidy ( Banshee), Siryn's father was on an INTERPOL mission, her mother, Maeve Rouke gave birth to her. But a while after she was born, Maeve was killed by a bomb, and her cousin, or uncle as she called him, Black Tom Cassidy took care of her until Sean got home. When Sean finally came home from his mission to find Maeve dead, he got angry at Tom for not looking after her, and he sonic screamed at him, breaking his leg, therefore Tom never got to tell him about Siryn.

Her First Drink

A year later, she had her first drink. She said she only took a few sips like the others, to dull the pain. But when they stopped because it made them feel sick and bad, Siryn kept on drinking. When she was fifteen, she found out that Black Tom had been arrested by INTERPOL agents.

Introduced as a villain

After taking down Black Tom Cassidy, and Spider-Woman enters the mint to find a trail of destruction from Siryn, which includes broken walls and unconscious people. Spider-Woman catches Siryn as she's breaking into the vault, in a costume modeled after her father's, and the two battle. During this battle, we see that Siryn is very skilled in using her abilities, even though she is just a teenager!. She was able to use a sonic lance, that Spider-Woman, during her monologue, said could have killed her. She also displays the ability to produce a forcefield capable of stopping Spider-Woman's venom blasts and she is also able to fly. When Spider-Woman hurls a sheet of metal (copper or silver, unknown) at Siryn, Siryn stops it with a scream, but is taken down by a venom blast. As she lies on the floor, the Juggernaut shows up and fends off Spider-Woman. The trio (Black Tom, Siryn and the Juggernaut) walk off as Spider-Woman lies on the floor.

In the next issue, and Black Tom, Siryn and the Juggernaut are on board a ship, but are ambushed by Spider-Woman and the X-Men. We see Siryn panic as the boat begins to sink after an attack by Colossus, and we also here Tom's inner thoughts, which show that he is some what concerned for Siryn. After the Juggernaut is taken out (Siryn thought he was disintegrated), Black Tom sends Siryn to "run interference". She is ambushed by Spider-Woman, but after being knocked over, flies up and out of the ship, her scream paralyzing Spider-Woman, causing her to let go of Siryn's back. After Spider-Woman was caught by Angel, Siryn used her powers to make him see a "sonic hologram" of a dinosaur, and then used her voice to take over his mind and make him drop Spider-Woman.

As the battle rages on, Spider-Woman leads Siryn into the ship. Siryn uses her voice as a sonar to find Spider-Woman. When sees Spider-Woman's costume, she blasts at it with her voice, but when the costume then lies on the floor with no visible body, Siryn becomes scared believing she killed Spider-Woman. This is not the truth, as Spider-Woman had stuffed her costume and she ambushed Siryn from behind with a venom blast, knocking her out.

Still unconscious, and the X-Men and Spider-Woman take the villains back to shore. Siryn is taken into an ambulance (still unconscious), and when Black Tom sees this, he gets angry believing that Siryn's hurt, but Spider-Woman assures him (as he's being arrested) that she will be fine in a few hours. Black Tom then tells the police that Siryn and Spider-Woman (the latter who had been falsely accused) had nothing to do with the crime. Spider-Woman later receives a letter from Storm, telling Spider-Woman that Siryn had been reunited with her father.

X-Force

She became a member of the mutant team, X-Force (and was a team leader). She also spent some time with X-Corporation, a mutant search and rescue organization.

X-Factor Investigations

X-Factor

Siryn later joined X-Factor: Investigations, formed by her former lover, Jamie Madrox.

When she first joined, Siryn was obtaining information from a woman named Victoria. Victoria had fallen "in love" with Siryn, but this was just because of Siryn's new found power, using her vocal cords to persuade anyone (bar mutants) to fall in love with her and be suggestible to anything she says, which Siryn used on Victoria to get information on Mr. Manetta, a man who made mutants lives miserable. Siryn pulled the pages from the envelope, and the pages are blank. The bar their in is suddenly ricocheted with bullets, killing Victoria. Siryn screams as Victoria dies in her arms. Siryn runs outside to chase after the gun man, insulting Strong Guy who's on the sidewalk outside, and was supposed to be back up. Siryn screams at the car and knocks it over, throwing out the woman who shot at them in the bar. Siryn shouts (shouts, not screams) at the woman to shoot at her, but the woman commits suicide.

Back at base, Siryn is just staring at bottle of alcohol, as Layla Miller enters. Layla asks if she's going to drink it, but Siryn explains that she used to be an alcoholic and just intends on staring at it.

As Strong Guy and Siryn talk over Layla, Layla drops in quickly that the woman who shot Victoria was "an operative for a Detective Agency called "Singularity Investigations," a kind of a security outfit for the rich and famous" as Layla said. Siryn does intend on storming into Singularity, but Layla tells her that that isn't a good idea, and she should take the client who's about to enters case (we see that Singularity had been expecting Siryn, but because a new force of chaos had been been introduced, her destiny had changed). Siryn takes the clients case, Gloria Santiago, who believes that her sister is being mind-controlled because she's been acting differently recently. Siryn goes to spy on Gloria's sister, and find out that it's not mind-control, but actually that she'd been sleeping with actress Jack Vaughn.

We see Siryn talking in her sleep about Ewan McGregor and lightsaber and about venturing down the toilet with him, and when she's woken up, she finds out that Gloria Santiago has been arrested for the murder of her sister.

Siryn flies Jamie over to the crime seen, and uses her persuasion power to get past a police officer. She is about to make Jack Vaughn confess to what really happened with this power too, but is stopped by Damian Tryp. The two then fly down to the police, to try and get the truth from Gloria, but she is in so much shock, she can't remember anything. Siryn then leaves when M arrives to read Gloria's mind to find out the truth, so Siryn flies back to Mutant Town to help out with the invading authority trying to stop the riots in Mutant Town. Strong Guy and Wolfsbane managed to hold them off, but Siryn delivered the final blow and sent the authorities with a scream.

Siryn offers Rictor to come and eat with her (after they get back to HQ), but he refuses. On the way to the cafe, Siryn is brutally attacked by Damian Tryp Jr. (because X-Factor humiliated the firm), and left to die in an alley. She is then taken in by a crazy ex-mutant doctor, who treats her injuries. She was hit in the neck with a drug that rendered her unable to speak or scream (that's why she couldn't retaliate), so she couldn't escape from the doctor's bonds, who kept her gagged and bound. Luckily, Rictor re-accepted Siryn's offer of breakfast, and decided to follow her. He arrives at the theatre where she's being held captive, and just as the crazy ex-mutant is about to attack him, Siryn breaks free and takes a single shot, pushing the ex-mutant, given Rictor a chance to kill him. She is then carried back to HQ by Rictor.

Siryn spends the next issue in bed, resting an recovering from her injury. A proper doctor comes to check out her injuries, revealing that it was a planned attack and the attacker knew where to hit to hurt her without killing her.

Denial

As Siryn recovers, she is visited by Cyclops, and receives the news that her father's dead. Siryn doesn't even re-act to this, and enters a state of denial, believing her father is just hiding to fool the enemies, and thinks he's still alive and says she isn't going to spend her time being upset only to have him waltz back into her life. Siryn watches the video her father left for her, explaining that she know owns Cassidy Keep. He also leaves her his special pipe, that he was given by his father.

Civil War

Madrox gave Siryn the mission of tracking down major superheroes to try and find the truth about the Decimation. She tracks down Spider-Man, and after helping him take down a crook, uses her persuasion to get him to tell her everything about the Decimation, and when she finds out, she's not happy at all. She thinks that they should go to the Institute and demand the truth, but then the X-Men show up in Mutant Town, demanding Quicksilver, but X-Factor show up themselves to defend him. Colossus makes a tiny gesture and Siryn sonic lances him, knocking him back. After a convincing speech by Jamie, the X-Men then leave.

Love Triangle

Paris

The two eat in a restaurant while talking, and hear a noise from outside. They run out to see a riot, burning down a mutant hostel, filled with depowered mutants. Siryn and M defend it, but when the police turn up, they decide to go peacefully instead of being felons. In prison, a man walks by who had just been arrested, and boasts about how the gang of rioters went back to the hostel after the police left, and burned the police to the ground.

After M crucified the man, the two broke out of jail and returned to the hostel, to find that the man was right, and it had been burned to the ground. Outside, they see the girl from the hostel window they saw the night before. She tells them her name is Nicole, and after a short discussion, M decides to take her home, despite Siryn being against the idea. They fly back in M's private jet, the same way they got there, but now as friends.

Return Home

When they return home, the team are facing a new crisis of the terrorist X-Cell. Layla gives each two members a note with a place to be to find X-Cell. Siryn and M go and stand on a corner of a street, and after they are believed to be hookers, three members of X-Cell turn up, Fatale, Marrow and Blob. Marrow stabs Siryn in the shoulder, and after being sat on by Blob, she screams and sends him flying.  After this brief encounter, back at HQ, Madrox sows up Siryn's shoulder.  Siryn then helps the others take down X-Cell.

A New Case

When some grandparents come to X-Factor asking for them to help them see their grandchildren again, the case is given to Siryn and M.

Siryn and M

When she wakes up, she's bagged and gagged to a chair in a small cabin, with M who has been chained to the floor. The two who attacked them were Solo and Clay, hired by Joseph Huber (The Isolationist).

M finally breaks out of the chains, and the two escape. While the Purity Singers and their parents are in an elevator, M and Siryn take the elevator to the grandparents, where the family are reunited. While M flies back to HQ, Siryn stays with the family.

Messiah CompleX

In 2007/08 X-Men crossover event, Messiah Complex, Siryn answers the call of Peepers who phones X-Factor believing he's being followed. When she finally arrives at the road he was driving on, only to find his car to be off the road, crashed, and Peepers body mauled.  She then prays over Jamie's unconscious body, praying for him to wake up, which he does.  She then takes part in the final battle on Muir Island.

Pregnant, Telling Jamie, Saving Mutant Town, And The Birth.

This arc begins with Siryn in a confessional booth, confessing about how been using the Lords name in vain, being jealous of M's iPhone and how she's been having impure thoughts about Jamie. She then revealed that she is also pregnant, and it's Jamie's baby (this confirms who's pregnant, because Nicole earlier in the series found a pregnancy test, and fans had been debating who was pregnant).

Note - We also find out in X-Factor #28 that because Siryn was so jealous of M's iPhone, M bought one for her and the other X-Factor women.

Heavily Pregnant Siryn

Next, Siryn tries to tell Jamie she's pregnant, but he jumps to the wrong conclusion and believes she's leaving. M says that Siryn would have realized this if she wasn't in love with him. She tries to tell him again but he's called away by Strong Guy. When M hears Rictor calling, Siryn flies after her with a Madrox dupe.

After M is taken down, Siryn arrives on the scene as Rictor manages to save himself from castration. Siryn then saves Rictor when he's nearly run over by Arcade's cars and manages to figure that the place where the robot was receiving it's commands was close (well, M did the work before that, but...).  Anyway, the team barge in to find the dying Purifier who recruited Rictor (during Messiah Complex), telling X-Factor that when he dies, so does Mutant Town.

The team then go and patrol the streets, saving innocents, Siryn saving a terrible comedian (an ex-mutant), who constantly tries to make Siryn laugh with terrible jokes.  After the trouble ends, the group head back to base, where Guido, M and Siryn rest their feet as they listen to a Daniel Day song ("Bad Day").  Jamie brings in Val Cooper, who gives the team an option of being put into the witness protection program or working for the government.  She gives them twenty-four hours to decide.  The team go to see Jamie who went to the hospital to visit the man, Nathan, who he helped earlier.  After finding out he died, Jamie asks Siryn can they name the baby Nathan after him, and as she goes to say it reminds her of someone (most probably Cable), she stops mid-sentence asking him how he knows (his conscious, as Layla, told him, telling him he had been noticing the signs), and then the whole team finds out.  The team then walk home happily together, and leave a pre-recorded message for Val Cooper, and blew up the building.  Five months later in Detroit, and a depowered mutant comes to the door looking for "XF Investigations", thinking she's going to be killed, and a heavily pregnant Siryn answers the door, telling Guido to ring Jamie.

When Siryn's water breaks she's involved in a siege of her home by government agents lead by Val Cooper who is shot during Rictor's attempt to save Siryn and the unborn baby under the impression the government have a vested interest in kidnapping the unborn baby. Madrox and the rest of the team meet Siryn at the hospital and Jamie surprisingly doesn't miss the birth of his child, he even takes lengthy safety precautions to ensure his baby isn't abducted utilizing his team members and dupes to watch over the baby and Siryn. She decides that she wants to name the baby after her late father Sean and the baby is named accordingly but then, on holding baby Sean for the first time something unexpected happens. Now mutant births are notoriously different and unpredictable but baby Sean starts to glow, then in Madrox's hands he is absorbed not dissimilar to one of his ordinary dupes. It is then apparent that on the night of conception it was infact a dupe which knocked Siryn up and not Jamie. Siryn attempts to claw baby Sean from within Jamie's chest but is unsuccessful, the episodes ends with Siryn breaking Jamie's finger and promising to break his neck.

Powers

Like the Siren's of the myth, Siryn can use her voice to make people fall in love with here, and in this state, they are suggestible to anything she suggests/asks. Mutants are immune to this power, but other superhumans aren't, like when she used her power to make Spider-Man tell her everything about the Decimation, after she was set a mission by Madrox. It doesn't matter what gender the person she uses her seduction powers on. When she uses this power she tends to emphasize on letters in the words, and use seductive language.

Siryn is able to use her sonic scream to fly, by screaming using it to propel herself. It is not known how she is able to use her voice to make her fly as well as others, as theoretically, she should only be able to float/levitate, but somehow she flies properly.

Siryn can also use her powers to enhance her hearing, use it as a radar sense of sorts, create force fields, stop current sounds from reaching others and talk so only one person can here (her powers are more like Sonokinesis than just sonic powers, but that is how they're described).

Siryn is immune to all of her powers.

Movie Appearances

Siryn appears in two of the three X-men Films. She is played by Shauna Kain. Her physical manifestation and her powers have stayed the same from what we have seen. In X2, Siryn is one of the children captured by William Stryker's men. Though she was tranquilized, she managed to wake up the entire school so they could escape. Her "Last Stand" appearance is nothing more than a few cameos.

Alternate Realities

Siryn of the Age of Apocalypse universe is called Sonique.
