Originally posted by Darkstorm ZeroI never got the impression that Frieza had less control over his emotions as his power increased, nor did I get the feeling that Cold was emotionally unbalanced either-- quite the opposite, in fact. You have any examples of this off hand? And Goku merely questioned whether or not Frieza's body was capable of withstanding the physical strain of reaching 100% power, nothing more.
Hows about I suggest that although all the Icehjins/Frost Demons/whatever the hell Freeza's race is, are born into their 4th form, and all the forms lesser than this are restricted power forms simply due to them being far too destructive upon maturing? With the exeption of Cooler, they all seemed to have trouble with actual control over their emotions, nevermind their powers...Id KC had such a high personal power, I can garuntee you he'd have even less control of himself tha Broly ever did, and if what Goku said to Freeza holds any weight, the race as a whole can only seem to handle so much of their own power.
My opinion: just because Frieza's 4th form was his true form, doesn't mean Cold was ever capable of reaching the same form. Like I keep saying: Cold was clearly not intended by Toriyama to have more powerful transformations that he could tap at will. If he were capable of amassing greater power than what he displayed, some type of canon source would have alluded to such(but none do.) And like Kento mentioned: even if we veer away from canonicity entirely, and reference all sources pertaining to Frieza's lineage, there is NO consistency in transformations whatsoever. Literally every member of that race can attain a different/peak form.
