The question is, would the viltrumites be able to stop before hitting the lightsaber? Say they could sense a viltrumite was rushing to attack them from a few hundred meters away. They’re fast enough in this case to move their saber to block them. But the Viltrumites also have enough reaction speed to see them start to block so now they simply change how they plan on attacking and stop before the saber to go around or just grab their hand.
