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 his escape.
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.

Earth, Megatron found a Mini-Con storage panel near the Decepticons' base on the Moon. He activated the panel and was pleased to see Leader-1 appear, as he was Megatron's personal Mini-Con from before their escape. Returning to the base, Megatron chastised the other Decepticons for missing a Mini-Con who was right under their noses. Leader-1 punctuated Megatron's displeasure with an incredibly powerful laserblast from his chest.Early in the search for the Mini-Cons scattered across
Leader-1 spent most of his time perched cutely on Megatron's shoulder, only springing into action when Megatron needed to unlock one of his powerlinx features.
Although he is shown to be very brutal with his Mini-Con brethren as he attack Perceptor with no hesitation, he shown a gentler side with humans and has seemed to have developed a connection with Fred as he hesitated to attack him when Megatron ordered him to.
After Megatron was upgraded into Galvatron, Leader-1 was never seen again.
Dreamwave Armada comic
Leader-1, head of Mini-Con village D10, was one of the Mini-Cons whose entire village was captured by the Decepticons at the beginning of the war one million years ago. He managed to get a distress call sent to Hot Shot, who then showed it to Optimus Prime. When the Mini-Cons escaped from the Decepticon fortress, Leader-1 had the misfortune of being with Megatron at the time, and thus had to serve him for the next four million years.
This routine went uninterrupted for quite some time, until Leader-1 and the rest of the Mini-Cons on Earth were abducted by Dualor and the rest of the Destruction Mini-Con Team and taken to the Mini-Con fortress on the Moon. When the Decepticons assaulted the fortress, Leader-1 shot the Destruction Team in the back and took over the control room, immediately contacting Megatron and giving him directions through the fortress. Ultimately, it turned out that Leader-1 had plans of his own, as he led Megatron into a security chamber and sealed the doors, before turning all of the automated weapons on him. As he gloated about finally getting his revenge for millions of years of indignity, pain, suffering, and torment, Dualor came to and shot him. This brief interruption provided enough time for Megatron to escape and tear his way into the control room, recapturing Leader-1.
Leader-1 ultimately regained his freedom when Megatron released him and the other Decepticon-held Mini-Cons in order to battle Unicron. And, as Megatron was slowly, tortuously, and systematically disassembled and destroyed by Unicron's internal defense systems, Leader-1 ended up having the last laugh.

- An abandoned character concept for Leader-1 was revealed by the Hasbro team during their panel at OTFCC 2003. The idea was that Leader-1 would have been deranged, thinking of himself as being the dominant one in his Mini-Con/Bulk partnership, with Megatron actually being HIS minion. This, obviously, was not used.
