Who has a novel similar to Douluo's Super Saiyan?

I'm not really sure. Maybe it's some kind of unique or symbolic element in the manga.

" Super size you, super size you, super size you again!"

I'm not quite sure. Maybe it's a reference to some specific manga scene or a fan-made concept. But I haven't come across a direct connection.

It's quite complex. Super Saiyan God is a more advanced form that builds upon the Super Saiyan concept, with unique powers and characteristics.

"Dragon Ball" was a Japanese manga with a Super Saiyan setting. It was published by Akira Toriyama in the magazine "Weekly Shonen Jump" from 1984 to 1995. The manga revolved around the plot of collecting the seven Dragon Balls to fulfill any wish. It centered on Sun Wukong, telling the story of adventure, hard work, passion, and friendship. Among them, Saiyans had the unique transformation form of "Super Saiyan." Transformation required high combat power and a pure and stable heart to increase the S cells in the body. Then, through extreme anger, the S cells would instantly explode to successfully transform (the previous generation's S cells could be inherited to the next generation, making the transformation easier). In addition, Super Saiyan 2 and other forms appeared in the original manga and related animations. At the same time, there was a Dragon Ball Doujinshi manga, New Dragon Ball AF. It was set in Super Saiyan 5 and other content, but the doujinshi setting had nothing to do with the original Dragon Ball setting.
