Butterdroid[1] (テフテフ[2] Tefu-Tefu?) is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, butterfly-based Badnik model created by Dr. Eggman that can fly.


Based on butterflies, Butterdroids have light-grey metallic armor with a pair of big yellow wings. They also have big, wide eyeballs and a small proboscis.

Game appearances

Sonic & Knuckles


Butterdroids first appeared in Sonic & Knuckles and the lock-on game Sonic the Hedgehog 3 & Knuckles, where they can be encountered in Mushroom Hill Zone. They slowly fly around in groups of two or three, but will attempt to spiral into the playable characters when they get close. This makes the Butterdroids easy to defeat in most cases, but they usually appear near Sticky Vines that the player can get caught on, making them more of a threat. Regardless, Butterdroids are easily defeated with the Spin Jump.

Sonic Generations

In the Nintendo 3DS version of Sonic Generations, Butterdroids from somewhere across spacetime appear as enemies in both Acts of Mushroom Hill. In this game, their attack patterns remain the same as in the previous game. Regardless, they can be easily defeated with a Spin Jump or the Homing Attack when they are aligned in chain formations so as to help the player reach higher areas.


  • Butterdroids never appeared in an issue of Sonic the Comic. However, it did appear in the 1996 Sonic Holiday Special on at pin-up, along with EggRobo, Sonic and other Mushroom Hill Zone Badniks.
  • Butterdroids bear an uncanny resemblance to the Pata-Bata from Sonic the Hedgehog CD.
  • The Butterdroid's Japanese name, Tefu-tefu, is a onomatopoeia for a fluttering noise.
