Well, Levi's back story might involve his childhood. Maybe he grew up in a tough environment. For example, he could have been in a poor family where he had to learn to be strong and independent from a young age.
Well, Levi was born in the Underground. His early life was full of struggle. He faced poverty, violence, and a general lack of order. But these difficult experiences also honed his combat skills and his will to survive. As he grew up, he got involved in various battles and gradually became the strong and respected Captain Levi we know. He joined the Survey Corps later, bringing his unique combat abilities to fight against the Titans.
Perhaps Levi had an encounter with a stranger during his travels in his early days. This encounter opened his eyes to a different way of life and broadened his perspective. This is an important part of his back story as it might have led him to make certain decisions later in life.
One possible plot twist could be that Levi travels back to a time when the Survey Corps was first formed. He might face the initial challenges all over again, but with his future knowledge. For example, he could know which recruits would be most valuable in the future and focus on training them earlier. Another twist could be that he travels back to a time before the fall of Wall Maria. He might try to prevent certain events that led to the fall, like uncovering a hidden conspiracy within the military that was planning to let the Titans in. It could also be that he goes back to a time when his past self was making a crucial decision, and his future self has to influence that decision without changing too much of the timeline, as that could lead to unforeseen and potentially disastrous consequences.
In the 'Attack on Titan' series, there is no clearly defined canon romantic interest for Levi. His character is mainly focused on his role as a soldier and his fight against the Titans. However, many fans like to ship him with various characters in fan - made love stories.
In the Levi King story, Levi King might be a very interesting character. He could be a person with a special talent. For instance, he might be an excellent musician who uses his music to bring joy to people or to tell important stories. Or he could be a great athlete, competing in some sort of challenging sport and showing great sportsmanship.
Well, if Levi is a character in a particular work, like in some anime or novel, the love story would depend on the plot and relationships set up in that world. Maybe Levi is a strong and silent type who falls in love with someone who breaks through his tough exterior. For example, if it's in a fantasy setting, they might meet during a dangerous quest and gradually develop feelings for each other through shared experiences of facing difficulties and protecting one another.
I'm not sure which specific Levi King story you are referring to. There could be many people named Levi King. Maybe he is a local hero in a certain community, or an artist with his own unique creative journey.
If Levi travels back in time, his character could develop more compassion earlier. In the original timeline, he had to go through a lot of hardships to become more empathetic towards his comrades. But if he goes back, knowing what he knows now, he might start showing more care from the beginning. For example, he could be more patient with new recruits instead of his usual tough - love approach.
