Goku vs Anakin? Is that even a real comparison? Anakin is nothing compared to any of the Z warriors. I mean even Krillan could probably take him.
Anakin can see things before they happen. When Goku jumps, he use the force to stop him and beging slaming him to the ground and crushing his heart at the same time.
The only way I can see Goku losing is if he let his stupidity and belief that everyone can change get in the way like its done so many times before on his show. Plus it seems like Goku would be able to overpower the force considering he has such a strong ki. I haven't seen the force do anything that truly surpassed all of the crazy stuff that they have done in dragonball Z
This is a pretty ridiculous fight to say the least. In a weird universe where it would actually happen, Anakin would win. Why? Goku would spend his time saying this: Now! This is your last warning! Leave now, or I will be forced to fight you! Meanwhile, Anakin kills him. But, if Goku were just trying to kill Anakin, it would be pretty instantaneous death. Instant transmission Kamehameha would probably do it. So, if Goku were like evil, he would win. If Goku were not evil, Anakin would be ruthless and kill. Of course, the Force would probably tell Anakin to dodge to the left. Who knows. It's a pretty improbable fight anyway.
