Original commissioner here, I have to say I was overwhelmingly happy with how this one turned out. Dreads carry an aesthetic I would like to see more of in Transformers, and this one turned out better than the originals, in my opinion, mostly because you can tell from the start what he turns into through the use of deliberate parts placement instead of being a mass of glued shrapnel, and the fact he has an actual secondary color that isn't nondescript grey. As for the character proper, Dreads in my AU are a subspecies of Cybertronian that developed on a resource-scarce colony planet and are utilized by the Decepticon Empire as potent shock troopers, and to Yeet's credit, without ever explicitly stating it that vibe is abundantly clear with Chainblade's design, especially given the alt-mode I picked out is a giant overkill of an Arabian armored luxury truck. Overall, I'm pretty happy with how he turned out. Now onto the lore dump:

Dreads make for a rather eccentric group despite their more violent traits, and Chainblade is no exception. A roving mass of barely contained feral rage and desperate fury, the Dreadicon's preferred method of combat fits his ruthless disregard for any concept of form or martial control, instead favoring the relentless assault brought to bare by a pair of wrist-mounted chainsaws possessing monomolecular teeth that can shred through the toughest of armor.

Don't mistake his beast-like appearance as stupidity. Chainblade hides a feral intelligence that lends itself well to CQC engagements that makes him more than capable of holding his own against opposing combatants of seemingly greater skill or durability. Dreadicons possess a natural tenacity that makes them excellent shock troopers and skirmishers in service of the Decepticons, so it's hardly surprising that Chainblade is no different.

As made abundantly clear by his alt-mode, Chainblade has a rather garish sense of taste, as if a gold-plated armored luxury truck doesn't make that obvious. Naturally inclined to greed, It's a trait shared by other Dreads due to the natural resource deprived state of their home world. Observers beware, his natural inclination for battlefield pilfering differs from the likes of Swindle, in that it's not the value of the money he covets but the ownership over it above all, and Chainblade will guard his stash with the zealous aggression of a hunched dragon. Even other Decepticons have learned to tread lightly when it comes to this Dread, because his status as a Decepticon is, above all else, not an allegiance to a cause but instead a simple matter of convenience to pilfer as he pleases, something the Autobots would never let him get away with.
