If Ralf is anything like his previous incarnations, you can fully rely on C and CD to win the day. They have great reach and priority with decent speed. He can out-poke out the best of 'em, though I don't know how effective this is in KOF13's combo heavy system. That's pretty much why I always played him in the previous games. The hilarity of the unblockable Galactica Buster was appealing too; punching through Ryo's Haoh Shou Kou Ken is always great.
