Super Saiyan 2

Super Saiyan 2 is ascended version of Super Saiyan. It's firstly obtained by Gohan durring Cell saga. Gohan defeated all Cell juniors with ease and he defeated Cell with ease.

Later in DB series it's still used by, not just Gohan, but Vegeta even. Goku also ascended to this form, but he's not using it much.

Appearance
Altrough Super Saiyan and Super Saiyan 2 look similar, they aren't the same. User's hair remains gold, but becomes more spiky. User also gets sparks around himself.

Power
It's power's higher than Super Saiyan's. It can be seen durring Cell saga that Gohan and Z-Fighters couldn't defeat Cell if they were Super Saiyans. When Gohan obtained this form, he was capable of defeating Cell juniors by simple punches and kicks, even Cell himself, but with a bit more power usage, since Cell's much stronger than Cell juniors.

Note: These are characters that use this in real Dragon Ball world.

 * Vegeta
