Tarn: The masked judge and Decepticon fanatic
In the dark universe of the Decepticons , Tarn is the pure embodiment of Megatron 's ideology—but taken to the point of madness. Leader of the dreaded Decepticon Justice Division (DJD), he reigns with terror among his own allies, ruthlessly executing those who deviate from the dogma.

The origins of the masked fanatic
Introduced in the IDW Transformers comics , Tarn is the charismatic leader of the DJD, an elite squadron tasked with eliminating deserters and traitors to the Decepticon code. His mask proudly displays the Decepticon symbol, which he considers sacred.
Behind this mask hides a once idealistic being, fascinated by Megatron 's writings. But his devotion has transformed into murderous fanaticism. He no longer fights for freedom, but for the purity of the Decepticon name.

A terrifying arsenal and powers
Tarn is not just an ideological leader: he is also a formidable fighter. His most feared weapon? His voice . Thanks to a built-in sonic modulator, he can disintegrate his enemies by modulating the frequencies of their internal circuits—a symbolic and cruel execution.
- Transformation: heavily armored Cybertronian tank.
- Weapons: dual fusion cannons, particle rifles, destructive vocalizer.
- Role: Head of the DJD, judge and executioner of Decepticon deserters.
His massive body and amplification systems allow him to face titans like Optimus Prime or Rodimus Prime . Yet, his true enemy is his own ideal, which has become his obsession.

Tarn: The Cult of the Decepticon Symbol
What makes Tarn fascinating is how he embodies ideological drift. Where Megatron dreamed of equality, Tarn sees only dogma. He kills in the name of a cause he no longer understands, transforming the Decepticon revolution into a religion.
His death, tragic and poetic, reflects the paradox of the Decepticon movement: an ideal born of suffering, perverted by excessive zeal and revenge.
