Knockout adorns his decorative armor for a “Officers Ball” in Vos.
Vosnian formal plating and cloaks vary based on rank. Each are custom made to suit the individual officer by a specialized tailor/ artisan.
Knockouts ornate formal armor signifies that of a High Commander “The Second Wing” to the “Lord of Vos.” The two dangling Red Crystals signify his rank along with the dual crests on his Ornamental Helm piece.
He holds a staff adorned with a Red Energon crystal. The Crystal in this case is indicative of his speed and cunning but also has always symbolized a passion to protect the city and its interests. The element albeit powerful inside is also prone to its own instability that is why it is shielded by three wings as a tine would keep order and protect its city.
Knockouts decorative armor is unique to him in that it is adorned with many wings and dual symbolic cockpits that rest on each of his shoulder. It signified his unique burden. Being he is the first high ranking Vosnian Commander in Cybertronian history without a set of his own wings, his tailor, whether in jest or genuine good intent to make up for what some deem his short coming saw fit to remind others symbolically that he belongs despite that fact.
The translucent cape symbolizes, loyalty, transparency and friendship with the Lord of Vos. It is also noted that only high ranking officers are allowed a unique cape and that none may touch the floor due to the tradition that this privilege is reserved for only the Lord of Vos himself, Starscream.
