The difference between a Grade B and Grade A lay in the level of their lifeform. After entering Grade A, one's genes would be optimized to become even more perfect. The body would become more adapted to the release of energy, and the energy loss would also be greatly reduced. At the same time, even the energy output would also be transformed. In layman's terms, endurance and attack power would increase. Thus, Grade A was known as the Calamity Grade.
As its name suggested, as long as they released power, a Grade A Super would definitely be able to wreak havoc akin to a natural disaster on a planet in a short time frame. Before the emergence of Beyond Grade A Supers, Grade A was the strongest level in the Galaxy.
Even then, Grade A remained a significant milestone.
