Suggested Sonic Nights can fly around and try to keep Primal at a distance but ultimately Primal’s going to win this one. His sensors are good enough where he could keep up with Nights’ speed and land some counter blows. The energy hits will take their toll as Nights’ durability is only okay. Nights will not have any easy way to land counter attacks and so this will mean defeat in the end. Primal has every advantage here. Optimus Primal wins.
