The set leaks confirmed that there'll be a new Decepticon that's on a league of his own so there's a lot of ideas about what role he'll play and here is some of them. 1. He's the three headed dragon: Supposing if Megatron isn't the dragon there's a good chance the dragon can be the new Decepticon. I mean there's not other explanation I can give to it. 2. He could possibly have broken ties with Megatron and his Decepticons: We know from the brand's history Megatron has dealt with Decepticons going against him and even to his army of Decepticons in some manner aside from Starscream like Shockwave from the Marvel comics and,Overlord and the DJD in IDW for example so who's to say that what happened between them resulted in the new Decepticon breaking away from Megatron's orders and forming his own Decepticon army to go against him and he's been doing it through the ages? Would explain the medieval scene in the trailer. 3. He's actually the one controlling Optimus: We have theories that either Unicron or the Quintessons are controlling Optimus but what if it wasn't either of them? What if the new Decepticon was the one pulling at Optimus's strings and he was using him to help bring Cybertron back with obviously at the expense of everyone else around him even to his own faction? That is something I can see happening. 4. He's either a new character or an old one. It's possible that this decepticon can be either a brand new character or someone from the brand's history redone here. Like he could be either a take on Cybertron Scourge,TFP Predaking or even Bruticus who we did get a dragon former with that name before. So what do you think? What are your theories on the new Decepticon?
