Lord Galvatron, Has there ever been a Soundwave from the aurex cluster that has had mini-con partners other than Laserbeak?
No. From my experience, the partner Soundwave held closest was no Mini-Con, but instead Sideways, for some ineffable reason.

Lord Galvatron, Has there ever been a Soundwave from the aurex cluster that has had mini-con partners other than Laserbeak?
No. From my experience, the partner Soundwave held closest was no Mini-Con, but instead Sideways, for some ineffable reason.
Dear, vector prime, two questions: 1. Have you ever fought in the clone wars of the lukas cluster? And 2. Was there a version of your brother, micronus, who was leader of the aurex minicons before his encounter with megatron?
Dear Clone Commando,
My visits to the worlds of the Star Wars are fleeting and infrequent. I did, however, once briefly stop over there while tracking a particularly determined version of Sideways, who thought he could lose me amidst a particularly fierce battle over the planet Coruscant during the Clone Wars. I chose an ARC-170 mode to discreetly pursue him; in hindsight, perhaps I needn’t have—the chaos of the Republic’s fighter mechs flipping in and out of their alternate modes to battle enemy drone fighters meant that my robot mode would scarcely have stood out amidst the melee, and I found the overly weaponized starship modes of this universe to be rather graceless.
As for your second question, I have never encountered a Micronus Prime amongst the Aurex Mini-Cons. In those realities where the Mini-Cons are creations of Unicron’s own cells, it would seem that the first Mini-Con was, in fact, High Wire. Although he possesses no connection to my own lineage, it seems fitting that the first of his race would go on to become one of the most important Mini-Cons in the ensuing conflict.
