I mean, you're telling me that they suddenly become incapable of controlling their eyebrow when they have the strength to rip a phonebook in half with their eyelid?
What is with everyone and phone book ripping anecdotes...?
Regarding the purity theory...
Keep in mind, I'm not here to argue over these theories. I didn't create any of them, they are derived from other sources. Well, except my opinion on the purity theory that people so love to vaunt.
But the theory I've seen in numerous variations is as follows:
To become a super saiyajin, a saiyajin must have a pure heart. Which is why it was possible for Gokou to go super saiyajin. However, as can be seen, those with a heart of pure evil (such as Bejita) can also go super saiyajin.
Like I said though, I think this one's pretty lame. Then again, I don't like getting into discussion over good and evil; they're conceptual perception of opinionated beliefs. You see evil, someone else sees good, another sees neutrality. How about we all see the vorpal bunny, and be happy with that?
Unofficial evolution/ascension level multipliers
This is based on speculation (you know that), and opinion. There's no point in getting distraught over any numbers quoted here, just speak your peace in a civil manner. Anyway, here are the numbers I tend to think of...
(These denote alternate names, or characters)
Saiyajin (
Gokou, Gohan, Bejita, Trunks, Goten, Trunks)
Factor 010 - Oozaru
Factor 050 - Super Saiyajin (SSJ)
Factor 075 - Ultra Super Saiyajin (USSJ)*
Factor 075 - Ascended Super Saiyajin (SSJ2)*
Factor 100 - Full Power Super Saiyajin
* -
The Ultra Super Saiyajin possesses the power of the Ascended Super Saiyajin, but the speed is only half of the character's speed, making its usefulness limited.
Shapeshifters (also called Icers;
Freeza, Cooler, Cold)
Factor 015 - Brute (Form 2)
Factor 030 - Feral (Form 3)
Factor 060 - Warrior (Form 4)*
Factor 075 - Warrior, Max Power (Form 4 100%)*
Factor 100 - Armored Warrior (Form 5)
* -
The max power form 4 is possibly just form 4, but after channeling ki, much like Nappa and Gokou do during the Saiyajin saga. In maximum power, the speed does not increaase.
Biological Weapon (
Cell)
Factor 015 - Hornet Warrior*
Factor 030 - Incomplete (Semi-Perfect)**
Factor 060 - Complete (Perfect)**
* -
I consider the first humanoid stage of Cell to be the hornet warrior; for he has evolved from the larvae.
** -
Perfect and complete are the same word; Perfect is a derivative of the latin perfectus which means to complete, or to be complete.
Android/Cyborg (
Android #13, Android #17)
Factor 065 - Super Form
Kaiou Shin (
Kaiou-Sama)
Factor 1.5 - Kaiouken (can be taught to others)
Factor 002 - Kaiouken Two
Factor 003 - Kaiouken Three
(all the way up to...)
Factor 020 - Kaiouken Twenty
Demon (
Janimba)
Factor 080 - Oni
Djinni (
Buu)
I'm not even going to try and speculate...
Nameccian (Piccolo)
Factor 010 - Unlock Potential (can only be done by a dragon caste nameccian (The Elder, Kami, Piccolo, Dende); can only be used on another being; can only be unleashed once)
Factor 020 - Fusion (Super Nameccian)
Hrmm.. Can't think of any characters other than this.
EDIT NOTE: Wiki is using the same theory I described in theory 2. See
this link. By an odd coincidence, they use the same terms I use, but for describing only the first type of Super Saiyajin.
