True Super Saiyan is a Saiyan transformation achieved by Vegeta Jr. during his training. Vegeta Jr. would later frequent this form more over time until eventually replacing the general Super Saiyan transformation.
While training, Vegeta Jr began to force his way to become stronger than Super Saiyan 2. But he ascended to an entirely different form. Vegeta Jr. would test the form's power on numerous fellow Saiyans, including Goku Jr. who brought him to a stalemate.
The True Super Saiyan form looks like the original Super Saiyan form, albeit slight changes. The hair is a deeper gold, the aura is defined, and the muscle mass slightly increases. The ascension is usually signaled by a glint in the user's eyes. A running gag throughout the series, villians often mistake True Super Saiyan as the base Super Saiyan form.
Power and Usage
The True Super Saiyan form is achieved by a Saiyan drawing out their laten potential to the surface and then having their bodies be accustomed to it. Doing so allows the user to have the strength of further Super Saiyan levels without feeling the various drawbacks, e.g. emotional instability or exhaustion. This actively bypasses stipulations need to transform into Super Saiyan 2 and 3. The most notable difference seen once transforming is the boost in speed and strength. The stamina is dependant on how well the user has control over their Saiyan power. The user will power down to Super Saiyan if their ki is depleted. True Super Saiyan can reach the power of Super Saiyan 2 and Super Saiyan 3, granted through vigorous training to harness that power. Vegeta Jr first used the transformation to battle Salla, Riku, Tora, Ryun, and stalemating Goku Jr due to ki exhaustion. Vegeta Jr. would present the form to his android clone, Vetora, who in turn transform herself. The two would battle, with Vegeta Jr. getting the upper hand in the end. Vegeta Jr. uses this form again against Android 21's second form. While the Saiyan was much stronger than the android, the tables turn when Android 21 absorbed Vegeta Jr's Galick Gun. Vegeta would yet again use the form this time against Froze, who desired to take Riku as her husband. Vegeta Jr. would fight on par with Goku Jr. who had recently achieved Super Saiyan 3.
