  • Speed and Power: The familiar is excessively strong; enough to crash through the school building's wall and it is fast for its size.

  • The only part of Krivoy Rog's body that is not armored is the skin under its tentacles.
  • As mentioned in the Terra Route, Krivoy Rog was supposedly made using a fossilized stone of an ancient sea creature that was alive millions of years ago.
  • Its name can be literally translated from Russian as Crooked Horn. It shares its name with a real Ukrainian city.
