Fullboar, or Uribo (ウリボ) in Japan, is a warthog-like Badnik that appears in Sonic the Hedgehog 4: Episode II.
Found in Sylvania Castle Zone, White Park Zone and Sky Fortress Zone, this Badnik is outfitted with four wheels for easy movement on land and comes in two varieties: a yellow model and a red model. The yellow model simply roams back and forth, but the red model is more aggressive and will charge at the player on sight. Regardless of their colour, this Badnik is easily dispatched with a simple Spin Attack or a Homing Attack.
|A Boar type robot newly developed by Dr. Eggman based on his research results from Episode I. They have been created with rich color variation, but Sonic should be extra careful of the formidable red ones that come charging towards him.
