Robot Butterfly[1] (パタバタ[2] Patabata?, lit. “Pata-Bata”), is a butterfly-type Badnik model created by Dr. Eggman that first appears in Sonic the Hedgehog CD. Robot Butterflies are seen flying around in many places without having any significant attacks.


The Robot Butterflies are based on butterflies. They have pink metallic body with wide eyes, yellow feelers and proboscis. As seen in Sonic the Hedgehog CD and Sonic Runners Adventure, they had round yellow wings, which are either clear or have holes on them in certain cases.

Game appearances

Sonic the Hedgehog CD

Patabata b

In Sonic the Hedgehog CD, Robot Butterflies fly around in a zigzag pattern in Palmtree Panic, so be careful not to hit them on the way up from a Spring, when the playable character is vulnerable.

Robot Butterflies are seen broken down due to age in the bad future of Palmtree Panic or sometimes in the present. Damage to them in their degraded state include holes in their wings which causes them to fly slower. They can be defeated by a single Spin Jump, where a flower seed from Little Planet will fall down ground from them after their defeat.

Sonic Lost World

Pata-Batas also appear in the Wii U/PC version of Sonic Lost World where they can be found in Desert Ruins Zone 2. At certain points in the level during which Sonic skydives, he must avoid multiple groups of six of these butterfly Badniks flying in circles. These Badniks however, are redesigned with blue wings and orange highlights, two holes in each wing, and a silver metallic body with a visible abdomen. Because Sonic is skydiving, he is unable to attack and therefore must avoid these Badniks instead of destroying them.

Sonic Runners Adventure

In Sonic Runners Adventure, the Robot Butterflies appear as enemies. In this game, they retain their design from Sonic the Hedgehog CD with the holes in their wings, though this does not affect their flight speed. The player encounters them in Green Hill.

In gameplay, the Robot Butterflies slowly fly towards the player. Other simply hover in place. Also, upon their destruction, they release an Animal.

Powers and abilities

In all their appearances, Robot Butterflies do not have any attacks, but instead fly back and forth in certain zigzag patterns. Some Robot Butterflies are also seen flying slowly due having holes in their wings.

The Pata-Bata in Sonic the Comic.

In the Sonic the Comic series published by Fleetway Editions, the Robot Butterflies are a part of Dr. Robotnik's Badnik army, although they only made a few appearances during the comic's run. Stationed in the Palmtree Panic Zone, the Robot Butterflies got relocated to the Green Hill Zone, where they began destroying the local inferior Badniks until the Seven Badniks brought them under control.


  • Interestingly, this Badnik shares its Japanese name, Pata-Bata, with another Badnik, Hoverby Mk II. The Hoverby Mk II are likely related upgraded models, due to their similar features.
