Often in fanfiction, Gohan's Super Saiyan 2 form can have new abilities. Maybe he can fly faster or has some sort of energy shield while in that form, which is not shown in the canon. His mental state in the form can also be different. In the original, he was often very focused, but in fanfiction, he could be more reckless or more in control depending on the story's plot. He might also use the form in situations where in the canon he wouldn't, like in everyday life just to show off or to solve minor problems.
In fanfiction, Gohan's Super Saiyan 2 form might have different power levels. For example, some fanfics might make him much stronger than in the canon, able to defeat enemies with a single blow that would give him a tough fight in the original story. Also, his appearance in the form could be more detailed or different, like his hair being a different shade of gold.
Fanfiction sometimes takes Gohan's Super Saiyan 2 form in unique directions. His power growth in the form could be tied to different things compared to the canon. For instance, instead of just training hard, it could be related to his relationships or his study of ancient Saiyan lore. The form could also have a different impact on his body. In the canon, there are some limitations and drawbacks, but in fanfiction, these could be completely different. For example, instead of getting tired quickly, he could actually gain more energy the longer he stays in the form, which would completely change the way he fights and the strategies he uses.
Gohan could become more of a leader. With the power of Super Saiyan 5, he would be one of the most powerful beings in the universe. Other Z - fighters might look to him for guidance and leadership. This could bring out a more assertive side of his personality. He would need to step up and make tough decisions for the greater good, which would shape his personality in a more authoritative way.
Sun Wufan's Super Saiyan 2 form was an important transformation form in Dragon Ball. In the Sarroux Game, Cyborg No. 16's epiphany allowed him to break through his limits and transform into Super Saiyan 2. In the final battle with Sharu, he defeated Sharu in the form of Super Saiyan 2. Other characters who could transform into Super Saiyan 2 were Sun Wukong, Vegeta, Future Trakus, Kaliphra, Gaga, Kefra, and so on. This form appeared for the first time in the manga Dragon Ball, and appeared many times in Dragon Ball Z, Dragon Ball MT, Dragon Ball Super, and Dragon Ball Hero. It also derived many enhanced forms (only counting the original Dragon Ball, series animation, series theater version, excluding games, non-Shueisha published manga (such as Dragon Ball AF.), non-Toei produced animation).
Sun Wufan had many performances in Dragon Ball Super. According to the setting, Gohan had entered the Super Saiyan Stage 2 in the Saru chapter. At that time, he reached this stage before the main character Sun Wukong. This could be said to be his peak moment. However, in the world of Dragon Ball Super, he could even be killed by a gun. His status and strength had changed. According to the official settings, his daughter, Xiaofang, was a mixed-blood Saiyan because Gohan's mother was an Earthling. Her bloodline was not pure. In addition, Beadley was also an Earthling, which further weakened her Saiyan genes. Therefore, whether it was in the original story or in Dragon Ball GT., Xiaofang could not transform. In addition, in the original story, the God Rice (a state of Sun Wufan) was the strongest individual character (excluding the combined character). However, this state would continue to weaken, which meant that the potential development effect of the old King God would gradually disappear.
In a fanfiction, Gohan as Super Saiyan 3 could be involved in a time - travel adventure. He travels back to a crucial point in Dragon Ball Z history and has to use his Super Saiyan 3 powers to change certain events. This could lead to a whole new timeline where things are different. For example, he might be able to prevent the destruction of Planet Namek or save some characters who originally died.
One idea could be Gohan in his Super Saiyan 4 form facing a new, powerful enemy from another dimension. He could struggle at first to control the raw power of this form while also trying to protect his friends and family. Maybe this new enemy has the ability to nullify the Saiyan's energy attacks, forcing Gohan to rely more on his martial arts skills that he learned from Piccolo.
In Dragon Ball, Goku's Unfettered Ultimate Skill Trainee Grand Priest form could be regarded as one of the strongest forms of the Super Saiyan. Its combat power index exceeded 10 billion. This form was a combination of the two states of the Ultimate Will Technique and the Great Divine Priest Trainee, achieving an invincible state of being stronger than the strong. However, with the development of the story and Wukong's cultivation process, an even stronger form might appear in the future.
From the current analysis, it was possible that the Ultimate Freedom Technique would develop into the strongest Super Saiyan form. There was a division of realms in the Ultimate Will Technique. For example, Weiss was in the second stage, Sun Wukong had mastered the first stage in the power competition, the Great Divine Priest had reached the fourth stage, and the fifth stage might be the realm that Sun Wukong had reached. According to the tradition of the Dragon Ball, Sun Wukong's strength was usually the strongest when it was close to the end. When Sun Wukong reached the fifth stage of Unfettered Ultimate Will, he might be born into the strongest Super Saiyan form. This was because from the first stage of Unfettered Ultimate Will that Sun Wukong had mastered in the power competition, it was similar to the previous Beyond One and Beyond Two forms. It could be imagined that when the hair of the previous Beyond Two, Beyond Three, and Beyond Four forms turned white, they would become the form of Unfettered Ultimate Will. Therefore, the higher stages of Unfettered Ultimate Will, especially the fifth stage, had the potential to become the strongest form. However, if Super Saiyan Four could evolve to beyond Stage Five, he might be able to rival the Supreme League Gods. However, it would be monotonous if he continued to evolve based on numbers. Moreover, in different plot situations, the strength of each form was also different. For example, in Dragon Ball Hero, Super Saiyan 4 and Super Super Blue were almost equal, but compared to Unrestrained Mastery, the gap might be large. The Supreme League God might also be the mainstream form in the future, while Gohan's mysterious form was relatively weak.
Super Saiyan 6 was a form designed by the Almighty. In terms of appearance, it more or less borrowed from Super Saiyan 5. Its hair was silver-white, its body hair turned black, and its body was surrounded by a purple divine aura.
There were many forms of Super Saiyans in Dragon Ball, and their rankings were more complicated and varied according to the plot stage, measurement standards, opponents, and other factors. Starting from the basic form, the normal form was the most basic form, followed by Super Saiyan 1. Goku transformed into this form for the first time in a battle with Namek's Frieza. This form's combat power was 50 times that of the original, and it was the foundation for many subsequent Super Saiyan forms. Super Saiyan 2 was significantly stronger than Super Saiyan 1. People like Sun Wufan could transform into Super Saiyan 2, and Sun Wufan could become Super 2 in anger and defeat Ultimate Saru. Super Saiyan 3 was also Goku's form in the Buu chapter. He cultivated this form during the netherworld, but although he had the upper hand against Buu, he could not fight for a long time. Super Saiyan 4 was the ultimate form of the Super Saiyan. It was transformed through the rational control of the Golden Giant Ape, and its combat power exceeded that of the previous versions of the Super Saiyan. The Supreme League God Wukong transformed into this form during the battle with the God of Destruction Bruce. His red hair appeared for the first time. Although he could not defeat the God of Destruction Virus, it was still a powerful form. Super Saiyan Gotten and Trunk (Trakus) were relatively weak due to their young age. Super Saiyan Vegeta was in a stronger form, and he continued to destroy Android19 in this form. Super Saiyan Goku's first transformation was significant, but after mastering a higher level, he was more inclined to use Super Saiyan 3 or stronger. In some forms of the Dragon Ball Super, the Free Ultimate Skill Wukong (including its ultimate form) did not rely on the brain. The body automatically dodged and attacked. When fully mastered, it had great strength, but it was said that the ultimate form had considerable side effects. Becket Super Blue was formed by the fusion of Sun Wukong and Vegeta. After the fusion, it became a Super Saiyan, and its combat power increased greatly. Sun Wukong's Ultra-Blue Realm King Fist was a form of the Realm King Fist that Ultra-Blue Wukong used to break through the limits of his physical body. It was powerful but consumed stamina. Vegeta Deep Blue had made a breakthrough on the basis of super blue. The Trakus Explosion was the form of the future Trakus under special conditions. Zamas 'Combination Form used the power of the earring to combine, and he was undefeated in several rounds against the Super Blue Becket. Kefra was a Body Integration Warrior, and her strength was comparable to the Super Blue Realm King's Fist. The Black Wukong Peach Blossom was the product of Zamas using the Super Dragon Ball to exchange bodies with Wukong. The more they fought, the stronger they became. In addition, there were some forms in Doujinshi works such as the Super Saiyan's five forms (such as Zhai Kou, Goku, and Gohan), the Super Saiyan's six forms (Goku and Gohan combined), the Super Saiyan's seven forms (the evil god Goku from another time and space), the Super Saiyan's eight forms, the Super Saiyan's nine forms, and the Super Saiyan's ten forms. However, these Doujinshi forms did not belong to the regular ranking set by the official Dragon Ball storyline.
In the manga, Gohan's Super Saiyan Teen form shows more raw power and determination. The visuals and energy manifestations are depicted with greater intensity.
