In the context of the “Dragon Ball” franchise, “SSJ” stands for “Super Saiyan.” The “J” specifically refers to “Saiyan,” which is a warrior race in the series known for their fighting abilities and transformations.
When characters in “Dragon Ball” transform into a Super Saiyan, they gain a significant boost in power, speed, and combat abilities. The transformation is characterized by a change in hair color (typically turning golden), an increase in muscle mass, and a distinct aura of energy. The concept of Super Saiyan is central to the story and character development, particularly for Saiyan characters like Goku and Vegeta.
The “SSJ” designation has various levels and forms, such as SSJ2, SSJ3, and so on, each representing a more powerful version of the transformation.
