Even though Prime is way bigger, I think he would get his ass kicked because he is a 'good guy' and the Terminator is a programmed Killing Machine! then again tho, the Terminator was initially programmed to kill Sarah Conner, and by the time he (it) found out that Prime wasnt a wee fleshy girl, he would be done for! hence my dilemma. I know for a fact tho that there is no way optimus Prime could stand up against the new T2 though, but I am still stuck.. Prime? T1?
