Vector Sigma? I mean she gave life to machines. She's linked with the allspark. She's like a supercomputer. She might be vector sigma. She also was the one who helped ressurect Prime in Transform and roll out, as if she was doing the will of the allspark. Maybe deep inside it was what the allspark was telling her to do. Isn't vector sigma the supercompter that was in charge of giving life to machines on Cybertron? Isn't Vector sigma the one that chooses the next Cybertronian leader in some continuities? Doesn't her key seem like the key of vector sigma? Isn't vector sigma/oracle the one that was prompting the evolution of the maximals in beast machines just as Sari caused machines to evolve in animated?(Example Prime's jetpack, Bumblebee's boosters) Wasn't vector sigma once a primate like creature in some continuities...and now Sari has a human form? http://tfwiki.net/wiki/Vector_Sigma I'm posting this now, since there is a big possibility that animated is to end. At least as a farewell.
She could be like a reference to the character, but I doubt she is the actual Vector Sigma node located in Malgus (the Animated Universe). The Key to Vector Sigma is also completely different from Sari's key, except in appearance.
Maybe, but if we take the matrix that has just been constructed in the most recent episode, there is a possibility that we were able to see at least part the making of the key to vector sigma. We haven't really seen any other candidate that fulfillls the tasks of the characteristics of Vector sigma, other than Sari. Who's to say that the Vector Sigma of the animated universe is a walking talking technorganic girl? Well not really expecting to get lucky and make the correct conclusion.. But does anybody else have an opinion on the matter or another theory?
.... Sari being Sari is good too. She's been a very interesting character and its great of have been able to watch her development.
