Mega Optimus Prime is a new larger-sized mold with the similar transformation scheme from the 3-Step Changer toy. It transforms from truck to robot in just 3 easy steps! His deco is based on his appearance in the season finale "Battlegrounds". He also obtains additional articulation on the arms, and sports connector ports for any Robots in Disguise (2015) Mini-Con figures.
The paint deco is... unfocused, to say the least. In vehicle mode, the grill, headlights, and bumpers (and thus his feet) are painted silver, yet the red in the small Autobot insignia has been removed. There is silver paint on the fuel tanks (toy battery cover), but not on the other tool boxes and equipment in the same location. There is also silver paint on all 6 wheel rims, the air cleaners, and the windscreen visor. In robot mode, the silver paint is mainly located on his thighs and crotch, though in order to save on costs, the dark blue and gold paint on his thighs and knee joints have been sacrificed.
Timelines Rodimus is a BotCon 2008 exclusive recolor of Classic Rodimus in black that is based on Black Rodimus. An evil alternate version of the Generation 1 character, according to the comic writers his personality is based on Vinnie Barbarino from the TV series Welcome Back, Kotter, using variants of Vinnie's famous put-downs. His new appearance has inspiration from the facial hair of parallel universe Mister Spock from the Star Trek episode "Mirror, Mirror".
In 2003, Takara introduced the Masterpiece MP-01 Convoy/Optimus Prime. While retaining the original concept of a transforming semi-trailer truck, this die-cast figure incorporated modern toy manufacturing techniques for improved detail and articulation, while, at the same time, captured the look of the cartoon character. It has since been released by both Hasbro and Takara Tomy in different variations. In 2010, a version of the Masterpiece toy, called Masterpiece Convoy Sleep Mode, was released, painted in dark colors to match the appearance of Optimus Prime after his death in the 1986 film.
The 1986 line featured another significant change in that many, if not the majority, of the toys were conceived as futuristic vehicles and bore little resemblance to present-day machinery. This was due to changes in the movie and television series, which leaped ahead twenty years to the year 2005. Many have speculated that this change might have been what signaled the beginning of the end for the Transformers, as part of the novelty of the first lines was the realistic vehicles that turned into robots.
Hero Optimus Prime was the first new-mold Optimus Prime toy created for the Generation 2 line. He transforms into a Kenworth truck of unknown model which defies Optimus convention by being one continuous unit, rather than the traditional cab-and-trailer combo. Decals form the windows of a faux truck face to represent his chest, featuring both his name and what appears to be a life support readout coming alive towards the end. In addition to a small gun, he is armed with a large missile launcher, which can fire a rubber-tipped rocket by means of a bellows which you slam your fist down on to produce a puff of air. The launcher is accessible in both modes, ending up mounted on his right forearm in robot mode; the bellows is attached via a rubber hose and cannot be disconnected, but stores on the figures's back when not in use, as do the rockets. A similar air-launching system with identical missiles was used by the simultaneously-released Hero Megatron, and by Laser Optimus Prime the following year (see below).
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
