[big][center]Kratos versus Sephiroth[/center][/big]
Now, to be clear, since there are several iterations and ability sets of either, this would be Mortal Kombat Kratos versus DDFF Sephiroth. Both have strengths and weaknesses that would most certainly make this a dynamic match.
Who do I think would win? Kratos, if barely. Sephiroth would drop Kratos to his knees and then get cocky, and then Kratos would find a burst of adrenaline and whittle Sephiroth's strength down to next to nothing, before yeeting him off with an uppercut into the ocean below. But what do you think?
