how are we all so sure that vader is not as powerful as sidious

i believe it too, but how, if he once was more powerful than sidious, suddenly become less powerful. i have heard explinations like the loss of body mass means less power, but i dont buy that. look at yoda, he has bugger all body mass compared to any jedi as he is so small yet his power is unnatural. i believe he could stop people from dying, but he believes its un-natural and not right so he doesnt. in the end, vader could kill sidious(albeit crudely) but it shows he had the power to do so. and about vader loosing his agility. why didnt they just patch him up, then build a propper body along the lines of Grevious's body for him. then he would be all powerful and agile. maby the fact that he had nothing to fight for now that padme was dead left him , not less powerful, but with nothing to fight for so he just submitted to sidious. what do you think?

 

uh maby its because hes more then half a robot know

 

uh maby its because hes more then half a robot
now

 

but i dont believe that losing body mass affects control over the force so that arguement falls over. he may have much robotic parts , but he is still anakin skywaker, concieved of midichlorians. so he should be as strong as he ever was, unless when padme died he had nothing to fight for and so nothing to focus all his powers on

 

i can see your point send a letter to insider ites a good arument

 

If Anakin/Vader was so strong even with the robotic appendages and the oxygen suit, then he should have survived the assault on the Emperor but he didn't so that moment is proof why he's less powerful then he was when his body was 100% intact.

 

anyway, he survived long enough to kill the emperor. what i think is that he had nothing to focus his power on saving after padme died, and so he simply submitted, however when he realises he has a son he has something to live for again and to try to save, and this is how he gets the strength to kill the emperor. he mightnt have died if he didnt take off his mask to look on luke. but he finally realised the difference between good and evil, and brought balance to the force, so his role was complete, therefore he could die peacefully, and he knew that death was not the end as we see him and yoda and obi wan at the end

 

Vader didn't seem to be any more patient than Anakin. I suppose he just never reached his potential. And his powers seemed to be more physical as Anakin than subtle.

 

Actually, GL says Darth Vader is less powerful by losing limbs because he has less midi-chlorians in his body. GL also says Vader is less than half of what he could have been and only 80%. of the emporer. I don't don't if you believe everything GL says or not, but GL is sure that DV isn't as powerful as the emporer.

 

Maybe Vader was still very powerful about the time he became Vader (I mean, helmet and all), or at least he might have been after fully recovering and learning to be in his new half-robotic nature.

But in time, and with less and less direct threats to him (because of the almost complete Jedi extintion), I guess he would have become soft and rely more on just his terrific appearance and some occasional force choking to impose on others.

Anyway, and after seeing III, I'm not at all convinced that Grievous is a good example of how a cyborg can be as powerful as a fully organic creature or even more; indeed, he looked relatively weak to me, lighsaber-centrifugation techniques aside.

 

I can go with Vader losing much of his body diminishing him. Even if 'we are luminous beings', we are still trapped in physical bodies and must deal with its limitations.
Vader is still very powerful, and also very intelligent. Had Luke never existed I think he would have eventually overthrown Palpatine.
