Overall, the Legend of Zelda manga has its merits. The plot can be engaging, and the illustrations are often detailed. But it might not be everyone's cup of tea due to personal tastes.
It's a bit hard to give an exact number. Different publishers and creators might have contributed to multiple versions. You might have to do some research to get a precise count.
It depends. Different Zelda fans and experts have varying opinions on this. Some believe it's canon, while others think it's not a direct part of the main storyline.
The 'Legend of Zelda Four Swords Graphic Novel' is mainly about the adventures in the world of Zelda. It likely features the characters from the game series, such as Link, and their quests. It might show the battles they face, the puzzles they solve, and the magical elements that are characteristic of the Zelda universe.
In the 'Legend of Zelda Four Swords Graphic Novel', Link is bound to be a main character. He is the one who wields the Four Swords and embarks on adventures. Besides Link, there could be other important characters like the various sages or the different races' leaders. And Zelda, as the princess, would be another key character. She might be in need of rescue or be an important part of the plan to save the kingdom. Also, there could be villains like Ganon or his minions who are main characters in the sense that they drive the conflict in the story.
The main characters are, of course, Red Link and Blue Link. Red is often depicted as being more hot - headed and eager for action. Blue, on the other hand, is usually seen as more level - headed and strategic.
One interesting plotline could be the two characters, Red and Blue, having to work together to overcome a powerful enemy that neither could face alone. Their different personalities, with Red perhaps being more impulsive and Blue more cautious, create a dynamic where they have to learn to understand and complement each other.
The Zelda manga can be good. It has its moments of excitement and adventure. However, it might not live up to everyone's expectations. It's worth giving it a try to form your own opinion.
