E-107 Theta[1] is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is a Badnik brawler created by Dr. Eggman that serves the Eggman Empire.


Theta resembles a large, stationary gun turret/tower hybrid that rests on top of a high-tech pillar. The majority of its body consists of two thick disk-like platforms that are colored columbia blue and white and are stacked on top of one another. Its bottom platform is wider than its top platform, and around its perimeter it has yellow rocket turrets. Its lower platform also has recesses along its edge that glow orange, while its top platform has gray minature turrets along its edge. It also has several gray pipes connected to its lower platform section (all of which are bent downward) and circular patterns around it. It also has a small and yellow platform-like head with a black face and orange eyes. Lastly, it has "Θ" written on its front.


The Fate of Dr. Eggman


Theta destroyed, from Sonic the Hedgehog #8.

Stationed inside the computer room in one of Dr. Eggman's pyramid bases, Theta and its horde of Spinas encountered Sonic, Silver and Whisper when they broke into their room. While Theta attacked the intruders, it was protected by the Spinas who kept the heroes occupied. When Whisper shot Theta with her Variable Wispon however, it retaliated swiftly. Before Theta could kill Whisper however, Silver blocked its missiles. Sonic then moved in and attacked Theta with a swift assault, destroying it and releasing the Picky that powered it.[2]


Theta is silent, but very menacing. It is quick to retaliate and is quite ruthless, being perfectly willing to attack its foes, even when they have no way to defend themselves with.[2]

Powers and abilities

Although it seemingly has no way of moving around, Theta is a powerhouse. It is capable of firing missiles, which pack enough power to incinerate a Badnik, quite accurately. It is also rather durable, as a Cyan Wisp-derived laser shot to its head caused little more than superficial damage.





  • E-107 Theta looks strikingly similar to the modified form of E-105 Zeta, an E-100 Series robot that debuted in Sonic Adventure.
  • E-107 Theta's title implies that it is a part of the E-100 Series first seen in Sonic Adventure, but this has yet to be confirmed.
  • Theta’s existence was first alluded to in the Archie Comics continuity, where it was first confirmed to exist through an entry on Archie Comics's official Sonic comic blog along with other previously-unheard of robots in the E-100 Series, and would later be name-dropped in the comic itself. Theta never made a physical appearance during the comics run, however.
    • This technically makes Theta the first Archie Comics-created character to be introduced to the IDW Sonic continuity.
