Well I don't really know. . .all i go is this. . . "The power of the Super Saiyan 2 skyrockets far beyond the power of Super Saiyan, Super Saiyan 2nd and 3rd Stage, and even Full-Power Super Saiyan. Perfect Cell and Bojack, who could both easily dominate those of the Super Saiyan and 2nd and 3rd grade levels and were somewhat stronger than Full-Powered Super Saiyan even without accessing their full strength, were easily beaten by Gohan in his Super Saiyan 2 form. In addition, when Cell produced the seven Cell Jr.s, each of the Z Fighters were unable to fight evenly with even one of them, though Gohan killed all of them effortlessly on his own in simple, single blows, and was unaffected by even their most powerful attacks."
