They could be the young, troubled boys in Gotham that Batman is trying to save. He sees potential in them and by singing to them, he is reaching out on a more personal level. Maybe they are part of a group he's mentoring or just random kids he's trying to make a positive impact on.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
There was an episode of " Days of Youth " called " Racing Song " in which a few boys sang a song called " Unbreakable Love " together. This song was composed by the famous musician, Lee Zongsheng, and was released in 2001 in Lee Zongsheng's album," Bewitched." The lyrics expressed a strong longing for love and a firm commitment. The melody was beautiful and moving, and it was deeply loved by people.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
😋I recommend to you "Starting from the Fast Men's Re-employment Boy Group." This book described the protagonist, Li Yi 'an, who won the first championship of Happy Boys at the age of 15, and led the Re-employment Boy Group to create a legend in the Chinese music industry in the summer of 2018. This book was similar to Happy Boys. It mainly described the protagonist's participation in a singing competition and his development in the entertainment industry. I hope you like this recommendation. Muah ~
Maybe Batman is singing to his sidekicks like Robin to boost their morale. He could be using it as a way to comfort them after a tough battle or a difficult situation in Gotham.
It could mean that a person who is a fan of 'Attack on Titan' (AOT) is reading or watching fan - created fictional works related to AOT. Maybe they are interested in seeing different interpretations or storylines that fans have come up with.
One way is to check on popular fanfiction websites. Look for ones with high ratings and a lot of reviews. For example, Archive of Our Own (AO3) has a large collection of AOT fanfictions. You can search for the most popular ones there.
Definitely not. AOT is a work of fiction that combines elements of fantasy, action, and drama. It's set in a made-up world with its own unique plot and characters.
