What are the main features of a treasury of Christmas stories and songs?

No, it is completely inappropriate. Such topics involve vulgar and inappropriate sexual content that has no place in educational or general social communication.

One of the best prosthetic arms in fiction is Luke Skywalker's in Star Wars. It's highly advanced, allowing him to perform complex actions like fighting with a lightsaber. It's also integrated well into his body, almost as if it's a natural part of him.

'Typhoon' could be a good choice too. It's an exciting adventure story on the high seas. You get to see Conrad's skill in depicting the power of nature and the human response to it. It's not as complex as some of his other works, so it's easier to get into.

Well, there's a fanfic named 'Naruto: Godly System'. In this, the system provides Naruto with abilities that are not only related to combat but also to things like leadership and strategy. It really changes the way he approaches his ninja life. Also, 'Naruto: The Ultimate System' is quite good. It has a complex system that unlocks various skills for Naruto as he progresses in his adventures, making for a very engaging read.

One way is to add some mystery. For example, Naruto might be acting strange and Sakura pouts because she can't figure out what's wrong with him. Then the story could unfold as she tries to uncover the mystery.

I've read 'Shield of Love: Naruto and Hinata'. It's a story that not only focuses on Naruto shielding Hinata physically but also emotionally. He stands by her side when she faces family issues and social ostracism in the Hidden Leaf Village. It's a heartwarming tale that really explores their bond.

Batman is obviously a very popular choice. Writers often like to delve deeper into his psyche, especially after the events of 'The Dark Knight Rises'. They might explore his internal struggles with coming back to the role after a long break or his thoughts on how to better protect Gotham in the future.

One idea could be a crossover where The Punisher teams up with RWBY characters to take on a new, powerful criminal organization in Remnant. He could bring his unique combat skills and no - nonsense attitude to the mix.

Sirius Black could also be an interesting character to pair with Hadrian. Sirius is brave and has a rebellious streak. He could add some excitement and a bit of a wild card element to the time - travel adventures. If they travel to a time when the Black family was at the height of their power and influence, Sirius could provide inside knowledge about his family's secrets and how to navigate that complex social and magical environment. Plus, his loyalty would make him a great ally for Hadrian.

Yes, there are quite a few. Some fanfics might focus on their unique relationship during their adventures in the One Piece world. For example, they could be on a joint mission where they have to rely on each other's strengths more than ever.
