Red XIII Solo vs. Odin [ 

This was the toughest by far in terms of strategy. Red is very mobile so survival is not an issue, but I had to get creative with damage in the form of Reaper Touch and a couple very well timed Retaliations. Probably the most fun I've had with figuring out these Solo Odin Battles thus far.
