Well, first off, her heritage as the child of Trigon and a human is crucial. It's what gives her such strong and dangerous powers. Her time in Azarath is a big part too. There, she was exposed to teachings and a way of life that helped her hold back her demonic side. Then, her decision to join the Teen Titans. This was mainly to protect Earth from her father. Her internal conflict between her good and evil sides, which stems from her parentage, is also a key element in her back story. It makes her a very complex and interesting character.
One key element is her parentage. Being the daughter of a demon and a human gives her a unique identity. Another is her upbringing in Azarath which influenced her power control. Also, her purpose of joining the Teen Titans to stop her father from destroying Earth is important.
Raven's back story is full of turmoil. As the daughter of Trigon, she has a dark origin. She was raised in Azarath, a place that taught her some discipline over her powers. However, her powers are directly linked to her demonic heritage. She has the ability to sense emotions and use magic. She came to Earth and became part of the Teen Titans as a way to keep her father at bay. Her internal struggle between her human and demon halves is a central part of her character. She constantly battles with the fear that her father's evil will overtake her and she'll be forced to do his bidding, so she uses her powers for good with the Teen Titans to prevent that from happening.
Well, in Titan Gilroy's back story, his determination is surely a key element. It's what made him keep going in the face of difficulties. His early exposure to the relevant work or technology is also significant. It could have been through a family business or just an early interest. And his ability to adapt to changes in the industry is another element. The industry is constantly evolving, and his ability to stay relevant and even lead in some areas is part of what makes his back story interesting.
The key element is her encounter with the tree and the spine - like thing which made her the first Titan. Another is her status as a slave which led to her being used by others for her new - found power.
The origin stories often involve a sense of self - discovery. Take Beast Boy for example. He had to learn to control his shape - shifting abilities and find his place among the Titans. His origin with the Doom Patrol also plays into his development as he transitions to the Teen Titans. His experiences with different groups and his own identity struggles are all important parts of his origin story and the overall Teen Titans' narrative.
In the Black Obsidian Raven Story, the relationship between the raven and the black obsidian is a crucial element. The raven might be attracted to the black obsidian for some reason, like it has a special energy. Also, the setting could be an important element. If it's a story based in a certain geographical area where black obsidian is found, that would add context. For instance, if it's set near a volcanic region, it gives a sense of the origin of the black obsidian and how it fits into the raven's story.
The key elements are her father being Trigon, a demon. Her mother was human. And she was raised in Azarath. Also, her powers like telepathy and dark energy manipulation are important elements.
The key elements are Titans, the walls, and Eren's motivation. Titans are the main threat, huge and terrifying. The walls are the symbol of humanity's defense. And Eren's hatred for Titans after his mother's death drives the story forward.
One plot idea could be that Raven, with her dark powers, gets transported to the Star Wars universe. Luke senses her unique power and they team up to fight a new Sith threat that has emerged, combining Raven's magic with Luke's Jedi skills.

Since they are often in a post - apocalyptic setting, they need to survive together. For example, in many fanfics, they use their different knowledge, Clarke's medical and leadership skills and Raven's engineering skills to get by.
One key element is the nuclear apocalypse that destroyed Earth. Another is the Ark, the space station where the survivors were living. And of course, the 100 delinquents being sent to Earth.
