Background Information

  • The Classic Caterkiller was based on the Caterkiller in the Sonic the Hedgehog video game series.
  • Unlike the Caterkillers used by modern Eggman, these badniks exhibited characteristic traits, such as fawning over the doctor and celebrating his birthday on their own volition.
    • They are also shown to be more expressive.
