Kevin Richards was the voice of Goro, Gregory Paul Martin was the actor, Goro wasn't a robot I'm pretty sure.
As for worst done character... You all are forgetting about Raynor Scheine, oh well you all might know him as Shinnok in the second movie? Yeah the guy that gets turned into a bunch of boxes at the end, oh they also say that he is Shao Kahn and Raiden's father... Yeah...
Now, I feel sorry for J.J. Perry... Pour guy had to play Cyrax(Killed in Movie), Scorpion(Given one hell of a dumb ass line), AND Noob Saibot(He came out of a guys stomach just to get beaten up by a girl...)
Speaking of girls, is it not ironic that they spend the whole first movie telling Sonya she needs to rely on friends, and then in the second movie get her double teamed by two ninjas?
The first movie was so well done, it would of been better without Kitana(Talisa Soto), and even better had Sub-Zero and Scorpion not been under Tsung's control, although he did say they were enemies. Raiden was done great although he should of done some competing. They found a great actor in Robin Shou for Liu Kang, and Reptile was done great, made him a secret just like he was in the first Mortal Kombat. I see where they were getting at with Scorpion's spear coming out of his hand, but they could of done that differently. Goro was awesome, Linden Ashby rocked ass as Johnny Cage, and Sonya had a great actor playing here(Bridgette Wilson) Tsung could of been better, made him older(who's the guy from the Karate Kid movies?)
The worst scene however was when all those guys come up from the ground to fight Liu Kang in the first movie, that was ghey.
However Red Williams(Jax) had a great line with "Damn, Sonya, you look good in mud."
I'll admit it, I agreed.
