DB is notorious for the various transformations it introduced in it's long history. But which one do you think made the greatest impact? Left you speechless over all?
Disclaimer: These are the transformations that took placein the anime ONLY and they are associated with Sayans. I excluding Ascended Super Sayans 1 and 2 and Super Sayans Ikari because Ι believe that they are sub forms of Super Sayan 1. I also exclude Super Sayan Blue Evolution for the same reason (sub form of SS-B).
Oozaru: The very first transformation. When Goku, while having his tail attached to his body, is seeing the full Moon, he transforms into a gigantic ape like creature deprived from any kind of self awareness and logic. It was revealed that when Kid Goku first transformed into this state, he accitentally killed his adopted grandfather Gohan Sr.
Super Sayan: Triggered by extreme anger after witnessing Krillin's graphic death by the hands of Frieza. Goku transformed into a spiked, blond haired entity with green eyes and surrounded by a golden aura. His speed and strength were completely rejuvanated.
Super Sayan 2: Triggered also by extreme anger. When Gohan sawCell crashing N16's head, he changed from SS1 to SS2. Even more spiked hair leaving only a stripe of hair falling on his forhead and surrounded by the same golden aua only this time there were frequent electrical discharges.
Super Sayan 3: First displayed by Goku to Mazin Boo but it was clear it was not the first time he underwent this transformation. It is not clear when precisely was the instant he first achieved this transformation but it is safe to say, it was some time during the 7 years between the end of the Cell Saga and the start of the Mazin Boo arc. Long golden hair and an ape like forehead, almost like the Hulk when he first appeared.
Super Sayan 4: Exclusive to the GT timeline which is now considered by fans as a alternate continuity. In theory, it is regarded as the pinacle of the natural evolution of a pure blood Sayan that still has his tail. Completely different compared to the other Super Sayans as this form has black slightly long hair and a body coated with pinkish fair. Goku had yellow eyes while Vegeta blue. This form is so powerful that can restore de aging and generate unique clothing for each Sayan.
Super Sayan god: Achieved by a special ceremony when 5 pure hearted Sayans join their Ki and give it to a particular indivisual of their choosing. Goku reached this state in order to fight Beerus. The user retains his original hair style but the colour of it as well as the pupils are now red. The user also posseses a much thinner body increasing his speed. Also described as god Ki.
Super Sayan Blue: Described as a Super Sayan god that has reached his own Super Sayan state. Almost identical to Super Sayan 1 only that the hair and the surrounding aura now blue. Goku and Vegeta reached this state under the training of Whis and they first displayed it when a newly resurrected Frieza invanded Earth.
Super Sayan Rose. Described as a god that posseses a Sayan body manages to reach the Super Sayan form of a Super Sayan god. It is also described as a form of mockery against the Sayans by Zamasu. Almost identical to Super Sayan 1 only the hair, the pupils and the aura are now light grimson colour. Zamasu while possesing an alternate timeline Goku's body managed to reach this state.
Autonomous Ultra Instict (both Sign and Mastered): It is not yet clear if this is a technique or a new form. It is described by Whis as a state in which, the body can decide and proceed to it's own responses, completely cut off by the brain increasing it's responsing time by a great deal. This state, for the time being is seperated by two subforms: Sign, in which the user has almost perfect defensive reaction when he is assaulted. In this form, the hair is slightly gone up, he has grey eyes and he emmits a great heat from his body. Mastered: The user has silver hair, he still has grey eyes and the emmiting heat is so intense that even clothing cannοt withstand. In this state, the user has both almost perfect offensive and defensive abilities.
Goku displayed this ability when he took a deflected Spirit Bomb from Jiren into his face while being in his Super Sayan Blue form.
