We're going BIG today on the Daily Prime with a look at the Titan and Epic scale bots that may be short on articulation but tall in size. Beginning with the Transformers Prime series in 2013, fans started seeing the jumbo-sized 12-inch and 16-inch Titan Optimus Prime figures at Toys R Us and 7-inch figures at SDCC 2013. The big hollow Titan bots reappeared for the 2014 Transformers: Age of Extinction with the 12" Heroes and 16" Guardians, and then again in 2015 for Robots In Disguise. Hasbro didn't end the BIG bots there carrying over to Rescue Bots line with a 22-inch EPIC Optimus Prime in 2014 and another 12-in EPIC Optimus Prime in 2018.
