Leader-1 (Unicron Trilogy)

Leader-1 is a Mini-Con from the Armada portion of the Unicron Trilogy.

Leader-1 was once a wise and benevolent leader of the Mini-Con settlements on Cybertron, but when Megatron appropriated the Mini-Cons for his evil purposes, he kept Leader-1 as his own personal attendant. Megatron was cruel to the peaceful Mini-Con, delighting in his misery, and all Leader-1 could do was silently plot the Decepticon leader's downfall. Slowly, maliciously, a dark corner was being tugged at within Leader-1's mind, as he realized he enjoyed his growing love for domination and sadism. One day, he insists, he'll do away with Megatron once and for all, in the most humiliating and painful way possible. It will be a delicious irony.
