If by Mortis anakin you mean the anakin that was amped to nearly his full potential and was able to control the son and daughter at the same time then he stomps. Not even the most powerful version of like or sidious could beta that anakin.
@deactivated-5c4df01082e4b: saying tennevrous is above caedus is basically saying tennebrous is above pleaguis and krayt. Which is very untrue. Since caedus is about equal or slightly superior to pleaguis and a good margin above krayt. Plus why are you arguing caedus is a weak link when krayt is on the team?
