Well, in a way they are. Mangas typically come from Japan and often have their own unique art styles, like big eyes for characters. Graphic novels are more of a general term for book - length comics. But they both rely on pictures and text to get the story across, so, yes, they are alike.
No. While most mangas share similarities with graphic novels, some mangas have very unique formats or storytelling methods that set them apart. For example, some experimental mangas might use non - traditional page layouts or play with the reading order in a way that is different from typical graphic novels.
The life of a centaur in mangas is typically filled with fantasy elements. They could have magical powers, be part of a hidden world, or struggle to find their place in a human-dominated society. It really depends on the specific manga and the author's imagination.
Well, 'One Piece' could be on the list. It has an epic adventure story, and the art is very detailed, which is a characteristic of graphic novels. The different islands, characters, and the overall world - building make it seem like a long - form graphic novel. Then there's 'Vagabond', which is based on the life of Miyamoto Musashi. The beautiful and detailed art, along with the historical and philosophical themes, gives it a strong graphic - novel - like presence. 'Berserk' is also a great example. With its dark and violent story, and highly detailed and often grotesque art, it has a lot in common with certain graphic novels.
In general, mangas don't typically have fillers. They tend to have a more focused narrative without unnecessary additions to stretch the plot. But there can be exceptions depending on the author's style and the publishing requirements.
