The legendary Super Saiyan is the fabled transformation spoken of in Saiyan history and utilized by the previous Super Saiyan who appeared 1,000 years ago. The "legendary Super Saiyan" is in fact the Super Saiyan and Super Saiyan God forms from Yamoshi's legend.
Several other forms have been believed to be the form from the legend.
- Legendary Super Saiyan: The final form of the first Super Saiyan state. Thought to be the legendary Super Saiyan due to matching the description of the form in the legends.
- Berserker Super Saiyan: A form identical to the "Legendary Super Saiyan" form.
- Golden Great Ape: The result of a Great Ape turning Super Saiyan. Thought to be the legendary Super Saiyan due to matching the description of the form in the legends.
Additionally, some video game stages use "Legendary Super Saiyan" as their title.
Several Saiyans have been referred to as a legendary Super Saiyan:
- Yamoshi is known as being the last legendary Super Saiyan who appeared 1,000 years ago.
- Goku is referred to as the legendary "Super Saiyan" multiple times in the franchise: the stage where he takes on the form of a Super Saiyan for the first time while fighting Frieza in Dragon Ball Z: Budokai, "Legendary Super Saiyan" in Dragon Ball Z: Budokai Tenkaichi 3, and a trophy for the video game Dragon Ball Z: Battle of Z features Goku called "The Legendary Super Saiyan".
- Broly is often referred to as "the legendary Super Saiyan".
- In Vegeta's what-if scenario in the video game Dragon Ball: Raging Blast where he fights multiple Super Saiyans in a dream, he states that he should be the only one to transform into the legendary Super Saiyan.
- In Raging Blast 2, when Adult Gohan fights Turles, he refers to the Super Saiyan transformation as legendary, saying "Behold, the legendary Super Saiyan!"
- In the video game Dragon Ball GT: Transformation, Dr. Myuu refers to Goku, Pan, and Trunks as the "legendary Super Saiyans!" upon capturing them.
- In Dragon Ball Z Kai, when Vegeta appears to Goku in a vision when the latter is losing his battle to Frieza, Vegeta tells him that Frieza will stop at nothing to destroy Goku, because of "a single over-riding fear", Great Ape Vegeta then continues from that same sentence: "that the legendary Super Saiyan will rise up from the ashes and obliterate him".
- In Dragon Ball Z: Resurrection ‘F’ and Dragon Ball Super, after transforming into the Super Saiyan Blue form, Vegeta mentions that he too (like Goku) can transform into the legendary Super Saiyan form.
- In Dragon Ball Super, Goku Black referred to Goku as the Legendary Super Saiyan after witnessing Goku's might from their first scuffle.
- In the Adventure Mode of Dragon Ball Z: Extreme Butōden, Supreme Kai informs Goku that in order to undo the warping of time and space caused by Omega Shenron's use of Minus Energy they need to seal the Minus Energy in the Ultimate Dragon Balls, but in order to do that they need the power of a Legendary Saiyan. It is later revealed the power of the Legendary Saiyan is actually the Super Saiyan God form.
- The Berserker Super Saiyan form is identical to the Legendary Super Saiyan form in appearance (with the only notable differences being a slightly slimmer build and more feminine frame, for obvious reasons), and even shares similar abilities to this form, even at one point being called "Legendary Super Saiyan" by Goku in the preview for episode 114 of Dragon Ball Super.
