* Initial Super Saiyan: Vegeta was already a Super Saiyan when Cell arrived. He fought Cell in his Super Saiyan form, but it wasn't enough to defeat him.
* Rage and Power Surge: Witnessing Gohan's potential and the destructive power of Cell's Perfect form, Vegeta was filled with anger and desperation. This intense emotion triggered a further transformation.
* Super Saiyan 2 Awakening: As Vegeta's rage peaked, his aura flared and his hair stood on end, signifying his ascension to Super Saiyan 2. His power level skyrocketed, allowing him to match Cell's power and even land a few blows.
Key Features of Super Saiyan 2:
* Increased Power: Super Saiyan 2 grants a significant power increase over Super Saiyan 1.
* Elevated Aura: The aura is more intense and electric, with lightning crackling around the user.
* Hair Changes: The hair becomes more spiky and stands on end.
Ultimately, Vegeta's Super Saiyan 2 transformation was a result of his immense rage and determination to protect his pride and the Earth. It showed his evolution as a warrior and his willingness to fight for a cause greater than himself.
