Sasuke Uchiha (Naruto) vs. Raiden (Metal Gear Rising Revengeance)
Haven't reached the end of Naruto, but I figure EMS Sasuke or above would be too much for Raiden, so this is Sasuke from when he fought Itachi. Raiden has his fully upgraded body which fought Armstrong.
I figure Raiden has the strength and durability edge, but Sauce has the ranged game and maybe a speed advantage.
If Sasuke loses, he gets a rematch at his Kage Summit ability level. If Raiden loses.....I guess he can take on Kid Sasuke.
