Well ...............i am sure most of you all have seen ROTK. U know when the oliphants are raiding the plains of Gondor (pelleneor fields) and they sweep away anything that comes through their path ?
i think GG will be sweeping the Jedi away like that . besides i am expaecting him to be very fast with his actions
besides it seems that when he outnumbered , he goes into spin mode ;
what makes him so agile is that his torso can turn a full 360 degrees from his waste upwards . so he can parry sabres from behind as well as from infront.
we have also seen a picture of him with four arms but i am not sure if they are his legs
