Tarn (G1)

Tarn is a Decepticon from the IDW continuity portion of the Generation 1 continuity family.

Tarn is the current leader of the Decepticon Justice Division. His devotion to Megatron is absolute, as evidenced in his welding of Decepticon insignia to his own faceplate. He bears the rather curious ability to manipulate the sparks of his victims purely by voice modulation, allowing him to literally talk someone to death. He vents the immense pressures of his duties through his addiction to transformation, which has caused him to burn through dozens of transformation cogs.

As his demands grew greater, Ambulon looked into rather unorthodox means of escaping this arrangement. How Ratchet Got His Hands Back
