As of right now, all the present Decepticons have seen a US release, and the only Bot to not have a toy that we've seen is Smokescreen, which makes sense, as he's new to the cast. But yeah, just got Dreadwing, set him up with Megatron, Screamer, Soundwave, Knockout, and my Vehicon and was like "Woah" when i realized that.
The key here is "present" Decepticons. Breakdown is no longer present as he is currently dead. Silas Breakdown was never really a Con. Jet Vehicons are present in the show so there is still one that's missing a US release.
Well, only Hardshell has a name, but no toy. Also, Shockwave needs a toy. Makeshift, I guess you can buy a second Wheeljack, plus he's dead.
I'd mostly meant primary characters... Breakdown is dead, Airachnid in stasis. I suppose I'd forgotten bout Hardshell. That said, I don't remember why I threw my vehicon in the first post.
Technically, since War for Cybertron is in the same continuity family as Prime, Shockwave already has a toy.
