With the revealed of Baldigus/Ruination (called it) for Unite Warriors EX and the story leading to Unicron's victory it's now time to ask what combiner, possibly the last combiner for the line, will be. Now this is all speculation and not based off any facts or rumors. This entire idea I'm only sharing because we all know how the story is going to turn for the better before it ends. Before getting into the theorizing it's important to list what molds/remolds have not been used by Takara excluding convention and Collector Club exclusives. Thus far Takara has not used the Battle Core Optimus remold and the Hasbro Strafe remold. The former only supports a new head while the latter includes that and more. While this is only two molds our of five it would not be a surprise if Takara created new heads for the remaining three members similar to Cursed Thrust and Ghost Starscream from the Grand Galvatron set. With the essential information covered I'm going to list what I think may be possible for this theoretical combiner. 1) Nexus Prime I make this suggestion based off the possibility Takara will use both remolds listed above. The Optimus Prime remold would serve as Heatwave and Strafe being re-purposed for Breakaway. The complications with this lineup, toy-wise, is that the Heatwave better resembles the Onslaught remold of Hot Spot. The second issue is that Breakaway closer resembles the Firefly mold than Air Raid's. Another complication, though specifically related to their origins, is that Nexus Prime was originally a Collector's Club exclusive. While this may or may not have any effect on a Takara re-imagining yet there is a possible loophole. Rather than basing it off the original Classics iteration Takara's remake could use the Aligned/Prime version. The characters are entirely different which could grant more liberties. They include Clocker, Mainspring, Chaindrive, Pinion, and Cannonspring. However this option is most likely not practical for a few reasons. The first being these characters originate from media Takara most likely doesn't acknowledge (not that I blame them) and excluding Clocker the rest of the gestalt are indeed original. Not only that but they have no visual references for toy design and their arrangement goes unlisted in any related media. Grand Galvatron may have included Roller from the IDW comics but they had a reference to work with. Mainspring, Chaindrive, Pinion, and Cannonspring have no such thing which may eliminate such an option. 2) A Unicron Trilogy themed combiner It's common knowledge that Energon's primary gimmick for most of the figures was the ability to Powerlink combine with other characters, be they only two bots or more. Although the designers already tried something approaching this idea with Optimus Maximus homaging Energon's Prime Force while using Generation One characters. Skipping over whether or not they succeeded in this idea there has been a few homages to past Transformer iterations in modern lines including Beast Wars, Beast Machines, and Armada. "But who could this team consist of?" one may ask. Well there are a few ideas which would make good choices. There are two characters that could be used from BC Optimus Prime excluding the prime himself. Thunderclash and Energon Rodimus. While the latter is a strange selection some of the profile does match. A crested helmet, a semi-truck alt mode, ability to combine, and a history of time-space meddling. Thunderclash was re-purposed from Rodimus but the original toy release was later used for Machine Wars Optimus Prime. Although Thunderclash is not a Unicron Trilogy character his remold deserves mention given the similarities to his design and the BC Optimus toy. For Strafe the answer may come as a shock. Energon Jetfire. Although a strange suggestion it's not impossible. The original toy was able to combine and Jetfire is a prominent character despite changing his identity between each show. What gave inspiration to this idea was Jetfire's repaint brother Overcast. His alt mode is space themed and his head design looks identical to Strafe's so it is possible for Jetfire to be used. This only leaves three molds left to finish the gestalt. Looking into other prominent Unicron Trilogy characters there are two that come to mind. Red Alert and Hot Shot. These two have a number of toys to take inspiration from for designs. For Red Alert his Armada design could be reinvented with First Aid's mold or his Cybertron Defense form with Rook. For Hot Shot there, surprisingly, isn't much variety in terms of molds. His Armada or Cybertron form could be used from the Dead End/Streetwise mold. Alternatively his Cybertron Defense design could be used Rook or Swindle/Hound. It is unlikely Rook would be used a second time but evidence of Wildrider and Slingshot may prove otherwise. This only leaves one member left to finish the team. Now I could list a number of characters including Energon Arcee, Cybertron Scattershot (named Backpack in Japan), Armada Blurr, and more. All of these are valid ideas for the fifth member but if I am to choose one character to focus on I have to choose one character above the rest. Armada Wheeljack (Rampage in Japan). I choose him for two reasons. The first being that out of the Armada Decepticons Wheeljack was one of the more interesting ones due to his backstory. He was a Decepticon but he had reason to switch sides and near the end of the series he accepting of an Autobot/Decepticon alliance. This would be a great mirror of the use of IDW Roller for Grand Galvatron to have a single Decepticon on an otherwise all-Autobot team. The second reason for his choice is mold selection. Wheeljack's original toy bears a resemblance to the 2008 Universe Sideswipe mold. That mold was used several times which included Sunstreaker an Breakdown. As it turns our we have a mold from Combiner Wars that was made with those two characters. Given this it would seem possible to make a Armada Wheeljack shaped head for that mold. With everything I wanted to say out in the open I now wish to see what everyone who reads this thinks. Do you think we'll see one last EX combiner or do you think Baldigus is the last of the line?
