Primus - TFO

Little things
Primus was the protagonist of the story in which he appeared. This means he was the most prominent, influential, and powerful of them all, and his role in the plot eclipsed all other characters in the popular Transformers franchise.
Primus can also be considered Unicron's benevolent counterpart. If Primus is the Creator God and God of Light for the Cybertronian races, then Unicron is his complete opposite, the Chaotic God of Darkness and Destruction for the Cybertronian races.
In the Transformers: Shattered Glass universe, Primus's counterpart was Dark Primus. However, if we're talking about certain aspects of his image as a noble and peace-loving creator, his counterparts would be Unicron and Gaia.
Primus was first mentioned by Terrorcon, nicknamed Scourge, when he fought and taunted Optimus Prime in the film Transformers: Rise of the Beast.

Primus' motto, which became a mantra for all Autobots.
Until everyone becomes one.

Primus, known as the Creator, is the main protagonist of Hasbro's Transformers franchise.

He is a benevolent godlike being from the Transformers multiverse who, at the dawn of time, battled his chaos-bringing twin brother, Unicron. The Lord of Light, Primus, created the Transformers to help him defeat Unicron. After defeating Unicron, Primus transformed into the Transformers' homeworld, Cybertron.

His presence is felt throughout the Transformers multiverse, but in some universes it is more palpable than in others. In some universes, he doesn't appear or even get mentioned, but all Transformers universes share one thing in common: the Allspark, the core of Primus himself, which in each universe is the source of life on Cybertron.

Story
At the very beginning
Before time, Order and Chaos existed within a superdimensional entity known as the One. To explore the nascent universe, the One created an astral being known as Unicron, then split him, creating his twin, Primus. Both brothers were multiversal singularities, unique in all realities. While Unicron could only exist in one dimension at a time, moving between them at will, Primus existed simultaneously in all realities. It is believed that the two brothers embody the fundamental concepts of reality—good and evil, order and chaos—and that their continued existence is essential to the stability of the multiverse.

As Unicron and Primus carried out their assigned task, traveling through space, it became clear to Primus that Unicron was a corrupted being, and he resolved to stop the threat his brother posed to all existence. In combat, Primus was no match for Unicron. However, he outsmarted his brother in cunning, shifting their battle to the astral plane and then back to the physical world, but in such a way that their essences manifested in the metallic plane.
