(For anyone interested in Tarn, I may want to work with you in future projects concerning him, so just keep that in mind. He will be a main antagonist in the future; therefore, it's very important to me who I choose. Make sure you are reliable.)

Tarn has looked up to Megatron, even before he had a name. Tarn was a fellow nameless miner in the dark caverns of Kaon, watching his fellow miners die harvesting energon for a tyrant. When Megatron rose against the oppressors, Tarn did not hesitate to join in the slaughter. Tarn and Megatron were sent to the Gladitorial pits to die, and while Megatron found the hate to slaughter those who stood against him, Tarn was less than adequate. His numerous battles caused severe damage to his face. Megatron took him as his protégé and trained him to be the greatest gladiator in Kaon, second only to him. When Megatron began the Decepticon uprising, he forged Tarn a mask to cover his shame, and thus forged Tarn into the ultimate Decepticon. Tarn grew to respect Shockwave for his loyalty to Megatron, and a friendship with Soundwave over their shared love for music. Megatron would name Tarn, Soundwave and Shockwave part of his elite council members, and the highest-ranking officers in the Decepticon army.
