Sad Emo Boy Crying BiographySource (Google.com.pk)
Raven is one of the longest serving members of the Teen Titans, in various incarnations of the team. Raven owes her heroic role (as well as an evil role) to a darker past - she is the daughter of a human mother named Arella and an inter-dimensional demon known as Trigon. Raven's demonic lineage was hidden from her for most of her early years. She was raised in an alternate dimension called Azarath, where she learned with a greater degree of skill to control her emotions by the goddess Azar. This was intended to control the influence of Trigon on Earth as her demonic powers would facilitate his ability to conquer the planet. Due to this training she rarely saw her mother and the two grew apart. Upon Azar's death she discovered for the first time her demonic heritage as she met her father face-to-face for the first time. This eventually caused her to leave Azarath and take residence on Earth where, after being rejected by the Justice League of America, she helped to create an incarnation of the Teen Titans.
Raven first appeared in an issue of DC Comics Presents in 1980. The series was commonly used as a way to highlight characters or reintroduce somewhat forgotten ones by pairing them with Superman. In this particular case, a new version of the Teen Titans was shown in a bonus section, of which Raven was one of the new members.
The timing was right for the new team, as youth oriented books were quite popular in the medium (the leader at the time was the X-Men at Marvel.) This led to these new characters becoming very popular themselves and very much established in the DC Universe.
Two of her early creators described her after her creation:
George Pérez: When I came to DC I came in strictly to do the Justice league. At the time Dick Dillin was still alive, so I just wanted to do one issue of it. Marv had asked me to do something for DC and suggested the Teen Titans. You know how hard it was to tell the people at Marvel what I was going to do at DC? "Oh, they finally got you doing work there, what are you going to be doing?" "Well, I'm doing the TEEN TITANS... (very low, embarrassed voice)" (laughter.) I did not think that book was gonna go. I loved the original, I hated the second version... and I thought it was going to die. Marv had already decided on Cyborg. Basically, he had all the things worked out on him. Same thing with Starfire. Raven ... while Marv conceived the character, it was Len's idea to put a mystical character in there. Marv didn't want Raven in.
Marv Wolfman: Len didn't specify Raven, he wanted a female mystical character. I just didn't want to do that because my first thought was Dr. Strange and my second thought was the Phantom Stranger. I didn't want to do anything like that. Len said, "Come up with something different." This was before Zatanna became a member of the JLA. And there were no mystical type characters in any group book. I had to figure out a character that would be completely different. from Dr. Strange, Dr. Fate or Zatanna. The name Raven came from the comic strip that I had done with Ross Andru. There was a girl in there named Raven Winters. And the last name went on to become the Baron's last name in Night Force. Raven sort of appeared that way.
The characters held no interest for me until a George did a visual. We talked about it and I was still very reluctant. While I knew about her background, I still didn't care about her because I don't like writing about mystics. He did the visual and I just went... "Wow." I knew what the face looked like, but at that point we had no intention or showing what her face looked like.
As is common with any character that first appeared as a teenager, Raven has matured substantially throughout her time as a hero. When first seen she was shy and withdrawn, but this was also as a result of not wanting to use her powers to their full capacity (or else her father would control her body.) Keeping her distance and her secretive nature made her hard to trust. Initially she was also a total pacifist and refused to actively engage directly in fights, but provided transportation and healing to her teammates. Although Raven began maturing as a character, unlike the rest of the characters on the Titans, this development came at the cost of potentially releasing her father upon Earth. As she accessed her emotions more often they came to affect her physical appearance and after she became completely corrupted she took on a demonic form and finally summoned her father to Earth. After his defeat she was revived and her normal appearance returned. During this time she struggled to better relate to other people.
For some time after the Titans Hunt story arc Raven was replaced with Evil Raven, an evil version of herself. However, it was later revealed that her true spirit lay bound to Starfire. Evil Raven was eventually reduced to ash and Raven's spirit for the first time was free of her father's influence. She would later be revived again by Sebastian Blood who needed her as a bride. After being rescued from this fate by her friends she developed more of a personality and even developed a Goth inspired fashion sense. After the events of One Year Later she decided for the first time to lead the team, alongside Beast Boy who were in a relationship together at the time (though they would break up from the strain the team placed on them). She later reformed the team alone (and began to wear a new costume inspired by the animated version.) It was soon after revealed that Raven had two brothers. In searching many worlds and dimensions for her father. On one her soul self partially detached from her leading to a sort of offspring, the Wyld. Lately, both Garfield and Raven have moved on from their failed relationship, though Raven feels great unease by the very presence of the newest member; Solstice, who's powers seem to drive Raven away or causing her to violently lash out.
Zachary Zatanna crush on Raven
Due to her odd powers and the potential for harm with unleashing her emotions her relationships have been somewhat abnormal. As well as her upbringing left her poorly in touch with her humanity, she at times manipulated the feelings of other to her own benefit. Her most enduring relationships have been with Beast Boy, though it has been well known that Wally West had feelings for her at different points. As well her relationships as a teammate have evolved over time and specifically to characters. She found much in common with Jericho and thus they shared a bond, which caused many people, like Deathstroke and Arella, thought the two are in a romantic relationship. At one point, she found herself in love with Dick Grayson and unintentionally manipulated his emotions into loving her (similar to what she had done to Wally West), the two shared a passionate kiss. Though with the help of Starfire, Raven realized that she is not in love with Dick and moved on with her life. The dark side of her character also left her open to manipulation by evil forces including Eric Forrester and Brother Blood. She also later developed a sort of flirtatious friendship with Zachary Zatara.
Raven taught by Azarathians`s monks how to control herself during her childhood.
After an absence of a year in the new 52, Raven finally appeared in the pages of Phantom Stranger as a teenager living in fear of becoming like her father. The Phantom Stranger intervenes when she comes under attack and seems to be interested in protecting her, but instead delivers her to her awaiting father despite her pleas as he was poised to invade the Earth to find her.
During the issue it is revealed Raven had escaped to Earth when her father Trigon had invaded Azerath some time ago, ending up at Stonehenge that serves as a portal between Earth and Azerath. It wasn't specified how long ago this exodus was or what Raven had been doing since then other than trying to help people with her empathic powers and avoiding the Church of Blood, Trigons earthly followers.
