During the Cell Saga, Vegeta unveiled Super Saiyan Grade 2, also known as Super Vegeta. This form resulted from intense training in the Hyperbolic Time Chamber.
Super Vegeta boasts increased speed and power by pushing Ki into every nerve of the body. Vegeta's pride played a key role in the naming of this transformation.
Despite its initial impact, Super Vegeta hasn't been seen in years. With new forms like Super Saiyan God and Ultra Instinct, it's a relic of an older arc, yet it remains a fascinating part of Dragon Ball history.
