It could be really interesting. Maybe in this fanfiction, Kenny and Clementine have some sort of adventure together. They might be facing challenges like dealing with walkers in the post - apocalyptic world. Their different personalities could lead to either great teamwork or some clashes.
The plot could involve them teaming up to rescue other survivors. Since they are both resourceful, they might combine their skills to save someone from a group of bandits.
One idea could be that the Overwatch heroes are transported to the Attack on Titan world. Tracer could use her time - traveling abilities to outmaneuver the Titans. Maybe Reinhardt's shield would be crucial in protecting the Survey Corps from Titan attacks.
One challenge is combining the two very different universes. Overwatch has a more futuristic, technology - based setting, while Attack on Titan is more medieval - ish with its walled cities and limited technology. So, making the two settings blend together in a believable way can be tough.
Perhaps Eren and his friends from Attack on Titan enter the Unordinary universe and are mistaken for having abilities. They then have to navigate the complex social hierarchy of the Unordinary world while also trying to find a way back to their own world. And the Titans might start showing up in the Unordinary world, causing chaos.
Without more details, Kenny could be anyone. He might be the protagonist of the story, a person with his own motives and desires. Maybe he's a young man who gets involved in a mystery and the secret is central to his journey. It's also possible that he's a more complex character with a backstory that led him to the point of abandoning this secret.
One possible plot could be that the Titans from Attack on Titan are somehow connected to the alien threats in Destiny. The Guardians could be sent to the world of Attack on Titan to investigate the sudden appearance of these giant creatures. They might initially struggle to understand the unique nature of the Titans, which are different from the enemies they usually face. Along the way, they could team up with the Survey Corps, sharing their advanced technology and combat skills. This would lead to some epic battles where the combined forces of Guardians and the Survey Corps fight against the Titans, while also trying to figure out the mystery behind their existence.
One interesting storyline could be where the fanfiction explores an alternate universe where the Titans have a different origin. Maybe they are not just mindless giants but are actually the result of a failed scientific experiment gone wrong in a more complex way than in the original series.
Eren Yeager is likely to be one of the most popular. His complex character arc in the original series makes him a prime candidate for fanfiction exploration. In fanfictions, he might be further developed, perhaps showing different sides of his personality or exploring different paths his character could have taken.
