For Ash, I've seen a fanmade iTunes cover with Alex as him and Lloyd as Darwin, so I think he should be him, as well as Peter as Darwin alone

For Caesar, I agree with Zach as him but maybe with Peter as Alexander the Great instead; both are ancient emperors who ruled most of the Old World. Plus, Castro vs Mao and JFK vs Nixon

For Link, someone once thought that RWJ could do the voice for him while played by someone else, since he seems to do the whole "yelling" thing pretty well like he did as Goku, so maybe him as voice and Jon Cozart as body
