Red XIII or Nanaki is a quadrupedal feral but intelligent creature resembling a lion. His fur is a dark brownish red color and sports a flame at the tip of his tail. He is roughly the size of a full grown male African lion. He is over a thousand years old, however his species lives a very long time so his age is more closer to 21 or so in human years maturity wise. He is the only known member of his species as they either died or were captured and never heard from again. He has been captured by Dr Hojo and experimented on so he isn't easy to trust strangers. His voice can be described as gruff and more mature sounding around strangers or others he doesn't trust.
