This rookie is called the Betamon. It is one of my favorites, and very rare. You have to take very bad care of your DigiMon when it is a Koromon to get one of these. It has a giant spike on its back. In battle, it shoots over 2 million volts of electricity. The Betamon can turn into a Darkmon, Airdramon, Seadramon, Meramon, or Numemon.
