Strauss is a powerful vampire and easily one of the only ones who can actually take on Thor and hope to win. Strauss showed very impressive speed and power feats throughout his series. Thor is clearly very powerful and he has blown up whole planets in the past, but I have a hard time seeing him keep up with Strauss in a high speed showdown. Thor is fast in travel speed, but when it comes to combat he will be a little outmatched. Strauss wins.
