A diminutive version of Megatron in his Walther P-38 mode was included as a new accessory with the Transformers Collection release of Starscream. Needless to say, he doesn't transform, but can be held by Starscream in both modes. Megatron's handle disconnects to reveal a peg, which can then be inserted into either of Starscream's fists, which were specifically resculpted for this purpose. Each fist also features a tab on its underside, into which Megatron's handle can be inserted, completing the effect. Megatron can also attach to Starscream's jet mode; the right-hand side of Megatron's handle features a square peg which is designed to fit snugly in gaps in Starscream's pectorals, as in the Generation 1 episode, "S.O.S. Dinobots". Unfortunately, this peg has, for no fathomable reason, been cast in the same sky blue color as Starscream's hands, unnecessarily making it as obtrusive as humanly possible. An additional tabbed right fist for Optimus Prime (complementing his then-upcoming Transformers CollectionConvoy release) was included as well.
Megatron's post is compatible with 5mm post fist holes, provided there is sufficient clearance for both the trigger and the back of the gun, and if you don't mind not using the handle.
Bang bang! He shot me down! Bang bang! I hit the ground...
Optimus Prime (2003/2004)
ID number:MP-1
Accessories: Scope, silencer, stock
20th Anniversary Optimus Prime included an accessory of Megatron in his classic Walther P-38 altmode. Although non-transforming, it is quite detailed and includes the individually removable silencer / barrel extension, scope, and (hinged) stock. Although notionally scaled to be wielded by Prime, Megatron is really rather small, so a diagonal sliding joint is added to his handle, allowing it to be lengthened and narrowed enough so that Prime can actually hold it. Both the stock and the sliding butt-end of the handle are made of a soft, rubbery vinyl, compared to the hard plastic of the other pieces. The stock extension connecting clamp is prone to breakage, much to the chagrin of owners who keep theirs sealed and untouched.
Needless to say, the later-released MasterpieceStarscream (and hisredecoes) can also hold this version of Megatron, and each include a small round clip that plugs in under their nosecones, allowing them to wield Megatron while in jet mode, as Starscream did in "S.O.S. Dinobots".
As the Masterpiece Optimus Prime mold has been has re-released multiple times, so too has Megatron. He was made available again without changes as an accessory for Takara's MP-4, "Convoy Perfect Edition" and MP-1L, "Convoy Last Production", and Hasbro's "DVD Edition", but has also been redecoed several times: these distinct new versions of Megatron are listed below.
Offered as part of a Lucky Draw campaign in August 2004, this extremely rare version of Masterpiece Prime is almost entirely vacuum-metalized gold, lacking any other painted detail or stickers. The same is true of the Megatron accessory, who is all chromed golden save for the butt of his handle and his stock, which are metallic golden plastic.
When Masterpiece Optimus Prime was recolored to become Ultra Magnus, Megatron received a new coat of paint as well: the black and brown color scheme of his Micro Change progenitor, which had previously been used on the e-HOBBY exclusive "Megatron Black Version".
The version of Megatron included with this black redeco of Prime—representing a mass-produced Eldedroid—was much the same as the original accessory, but with dark metallic silver paint.
Now even more breakable!
Convoy Sleep Mode (June 2010)
ID number:MP-4S
Accessories: Scope, silencer, stock
Just as this release of Optimus Prime was recolored in the faded black and grey hues of he took on with his death in The Transformers: The Movie, so too did his Megatron accessory get a movie-themed makeover: this Megatron is cast entirely in translucent purple plastics, evoking the scene of his transformation into Galvatron from the film, in which he is first reduced to a transparent purple wireframe model.
A repaint and retool of the Megatron gun originally included with MP-01 and his redecos, the Megatron gun included with MP-13 Soundwave has been retooled in response to the breakage issues the original version suffered from. Both the sliding butt-end of the handle and the stock have been molded in hard plastic instead of the soft rubbery vinyl of the MP-01 version. A joint has been added to the stock connection point on the handle; for the joint in the stock itself, a straight pin has replaced the original rivet-style pin the softer plastic required. The stock itself no longer emulates the transforming accessory from the G1 toy, and instead features a smaller cylindrical shaft that more closely resembles the original U.N.C.L.E Special. In terms of deco, the minute red paint application on the scope is omitted.
Soundwave (2013)
ID number:MP-02
09 OF 30
Accessories: Scope, silencer, stock
The Hasbro version of MasterpieceSoundwave also comes with the Megatron gun. It is seemingly unchanged.
A repaint and retool of the Megatron gun originally included with MP-01 and his redecos, the Megatron gun included with MP-13B Soundblaster features the same retooling as the version released with MP-13 Soundwave, although this time the pieces are cast in translucent red plastic. The only paint application is a silver Decepticon symbol.
Accessories: Left and right fists, translucent right fist, gun barrel (opaque and translucent), saluting right hand (opaque and translucent), "Laser Vulcan", stand, die-cast Megatron Gun accessory (Asia reissue)
When reissued by Hasbro Asia in 2016, MasterpieceLaserwave included a non-transforming diecast Megatron gun accessory which could be held by Laserwave. The accessory is similar, but not identical, to the Megatron gun included with MP-01/MP-13. Of particular note, the very detailed single-piece accessory is sculpted with the barrel extension and scope, but not the stock, and features the loop/swirl pattern found on the original toy's robot mode chest.
The all-new-for-2021 MasterpieceStarscream includes his own Megatron gun mode accessory, produced without a removable scope or stock. Megatron can peg underneath Starscream's fuselage in his vehicle mode, or his handle can extend for Starscream to wield him in robot mode.
Despite a history of many Masterpiece Starscreams and many gun mode Megatron accessories, this is the first time that a Masterpiece Starscream has actually included a Megatron!
G.I. Joe featuring Ninja Force and Transformers (2017)
A redeco of the above gun mode Megatron accessory was included as part of a G2 crossover set sold by Fun Publications, again for use with Cobra Commander.
It should be noted that this is the first Generations toy to depict his alt mode as a gun, albeit in a non-converting accessory form. It was soon followed by the Kingdom Core Class toy below.
Walmart once again reissued the original Starscream toy in 2023–now in more cartoon accurate colours–under the Transformers Retro label. He retains the gun mode Megatron accessory first included with The Transformers Collection Starscream.
Unlike the original versions of Starscream's fists from The Transformers Collection reissue, the fists from this version are cast in black plastic and painted blue. The added paint makes the post on the bottom of his fists thicker than they should be, so attaching the lower portion of the Megatron gun can be difficult.
