Modern Day Beowulf

 The modern day Beowulf would be Batman. Beowulf didn't really have any super powers and neither does Batman. Beowulf was a really good fighter and batman is a black belt. They're fighting styles are kind of similar but Batman uses gadgets and has Robin to tag along. Given that I watch both movies with these guys being the main character Beowulf is more of threat to villains than Batman because it takes Batman almost the whole movie to beat Bane. Beowulf wasted no time when he was showing Grendel the ropes. Since Beowulf fought Grendel I would say it's only right if Batman threw down with "The Thing" from fantastic 4. Grendel was a sort of an easy match for Beowulf and I feel like the Thing might give Batman a little challenge. This most likely would never happen because batman is in DC universe and the Thing is in marvel. I feel like Batman would get demolished by Grendel but not his mother and I also feel like Beowulf would get smash if he fought Bane, Joker, Penguin etc. All in All Batman is as close you can get to the modern day Beowulf.
