Micronus Prime

So, if the Mini-Cons are Pokémon, does this make him Arceus?

At the dawn of time, Primus created Micronus Prime, conscience and moral center of the Thirteen. Although he is the smallest member of this venerated group, he possesses boundless reserves of energy and a clever mind, enabling him to predict the actions of his brothers and sisters before even they know what they're going to do.

Micronus's innocent nature belies his strong ethical sense; although he takes his role very seriously, he approaches his duties with a light Spark and an easy touch, eschewing the most dour members of the Thirteen in favor of the free-spirited Onyx Prime, whom he once considered his closest friend. His creative energies inspired him to strike up friendships with Solus Prime and Nexus Prime. Micronus's siblings always appreciated his presence; he could impart a fraction of his energy upon them using the Chimera Stone, directing his own energies into a form that suited his ally's needs. He would pass this ability on to his descendants, the Mini-Cons.

In recent years, Micronus Prime has retreated to the Realm of the Primes, where he temporarily served as a mentor and spiritual guide to Optimus, the youngest member of the Thirteen. In this role, he prefers to let his younger sibling through trial and error, sometimes feigning a blithe indifference to the mental and physical rigors of his training regimen. In reality, though, Micronus cares deeply about all living things, be they Transformer or otherwise.

The Covenant of Primus

Micronus Prime was the fifth Prime created to battle Unicron. His artifact of power was the Chimera Stone, which allowed him to temporarily impart his fellow Primes with additional power. He served as a strategist during the battle against Unicron, and struck up a deep friendship with what would become his closest friend Onyx Prime. In the age that followed, Micronus became friends with Solus and Nexus Prime. The schism caused by Solus Prime's murder and which ended Liege Maximo's death left him grief-stricken and inconsolable. When Onyx Prime entered the Well of All Sparks and created the Transformer race, Micronus accompanied his best friend on this mission. Their sacrifice activated the Well and allowed it to start producing new life. The Covenant of Primus

Stop trying to impersonate Tony Stark, Micronus; you sound terrible!

In the Realm of the Primes, Micronus served as Optimus Prime's mentor as the Autobot leader trained for a new mission on Earth. In one such training session, Micronus challenged Optimus to climb a hill. When Optimus questioned the difficulty of his task, Micronus summoned a group of humans into the realm... and a threatening robot with multiple Mini-Con minions to attack them. Optimus tried in vain to defend the humans, repeatedly begging Micronus to help him, but Micronus declined every time. Eventually, Optimus realized that he needed to climb the easily-climbed hill first, which activated his Prime Decepticon Hunter and gave him the power to defeat the robots, saving the last surviving human. At the end of the test, Micronus revealed that the humans were merely illusions, meant to prove that there would always be distractions and hard choices in the battles coming, and to keep the goal -and mind- clear.

The Transcendent Technomorphs of Axiom Nexus knew the Mini-Cons to be the children of Micronus Prime. Rook - Axiom Nexus News, 9/5/2015

When Nexus Prime united the Terminus Blade and the Star Saber, the other Thirteen were drawn to the event—including Micronus. Time and space were rewritten that day, as the walls between the multiverse grew stronger and less permeable. A consequence of strengthening the walls of the multiverse was that Micronus Prime and the original Thirteen could no longer continue to exist as multiversal singularities, and so they were splintered and scattered throughout the multiverse. And so the one became many, sentient reoccurring themes each appearing in their own way, if at all, in all the worlds of the multiverse. Out of the One, Many

Micronus's name is likely derived from "Micron", the Japanese name for Mini-Cons across the franchise.
The glowing symbols on his chest and palms are shaped like the Powerlinx ports seen on all the Transformers: Armada Mini-Con toys.
