Chimera Stone

If Micronus Prime and his massive supplies of energy can be likened to a living battery, then his Chimera Stone is the conduit through which he focuses his power. As his chosen artifact, he can channel his energy to any other member of the Thirteen; while connected, the stone allows him to direct his energies to best suit the needs of his allies.
Fiction
The Covenant of Primus
Shortly after the birth of the Thirteen, Solus Prime created the Chimera Stone for Micronus Prime using her forge. Micronus used it often as the Primes prepared for their battle against Unicron, adding his own power to Solus's strength as she worked to build weapons and armor for the Primes.
After the death of Solus Prime, an incensed Micronus used the Chimera Stone on Onyx Prime; as the Primes interrogated Megatronus about his part in Solus's death, Micronus angrily channeled some of Onyx's power to transform into a furious, animalistic version of himself. The Covenant of Primus
2019 IDW continuity
The Chimera Stone was an artifact believed to have existed at one point or another. While residing within House at the Sea of Rust, Termagax pondered on whether the Thirteen were metaphors meant to explain the mysterious powers held by the artifacts. Lord of Misrule: Sea of Rust I
Toys
Age of the Primes

- The Thirteen Micronus Prime (Deluxe Class, 2025)
- Known designers: Mark Maher (Hasbro), Takashi Kunihiro (TakaraTomy), Aaron Archer and Ken Christiansen (original concept)[1]
- Part of the third wave of Age of the Primes Deluxes, Micronus Prime features his Chimera Stone in the form of a small disc accessory bearing his personal sigil which can store on his back in both robot and alternate modes, or peg onto the included Apex Armor-inspired exo-suit in either of its modes, either front and center on its chest or in the wheel well of its unicycle mode. Additionally, the toy's product copy suggests that Micronus himself transforms into a larger version of it, though this seems more like a miscommunication than intentional design.
Notes
- The Chimera Stone's appearance in "Lord of Misrule: Sea of Rust I" was inspired by the visual of an atom with electrons.[2]
Foreign names
- Japanese: Chimera Stone (キメラストーン Kimera Sutōn)
