REVIEW: Mastermind Creations R-48 Optus Pexus (part 2)


We’re back for the second half of our deep drive with Mastermind Creations latest unofficial effort – Optus Pexus. As we talked about last time, this toy is an IDW-styled representation of the Autobot’s most iconic leader, and looks very swish indeed!

That vehicle mode proved to be a sturdy yet attractive specimen but now it’s time to get him all contorted into robot form for review, a process that really doesn’t require too much patience on your part, rather fortunately!

Everything moves in much the way one might expect of any Optimus Prime design, with the blue bits forming the legs and the red bits forming, well, everything else. There’s a bit of complexity in terms of how the backpack comes together but everything tabs in neatly and securely once you’re done. I would advise a little caution in how various panels rub against one another just a smidge, if only because I have already noted a small scratch on the red paint on my copy, although fortunately on an interior-facing panel.

Really though, there’s not much to bother seasoned collectors here, despite a few clever touches such as the little pistons in the knees. Once you’re done, it leaves you with a very handsome robot, and one that surely needs no introduction – it’s Optimu— er, Orion Pax!

Yes, in this case, it’s the robodad’s younger self that’s the intended character, although really, call him what you will when he looks as magnificent as this, eh? Not only a handsome beast in its own right, but chock full of signature Optimus design cues and a seemingly very faithful representation of his IDW appearance to boot.

And did I mention handsome? I did? Because oh boy, just take another look, why don’t you? Optimus toys have an innate knack of being easy on the eyeballs at the best of times, but just occasionally you get one like this that makes it appear all too effortless somehow. Every inch of him exudes a charm that’s rather unmistakable even from the other side of the room.

First, there’s that head sculpt, which is a spot-on representation of everyone’s favourite Autobot for the ages and features a pair of luscious baby blues to boot. I have a slight critique in terms of how the neck hinges backwards rather awkwardly but otherwise, this is one notable noggin.

Then there’s the stylised take on the classic window boobs, which look altogether different here by way of that snowplough-styled front bumper stuck in the middle. I like the way the blue panels catch the light and overall it all adds a touch of something unique to Pexus’ pectoral region.

That’s followed up by a somewhat more traditional abdominal section, with a truck grille popping up out of nowhere despite not having featured in the vehicle mode! That’s a strange choice in many ways but it does follow the IDW character template and I guess could be explained away as some bit of Cybertronian tech that just so happens to look identical to the corresponding section once he undergoes his Earthern transformation, eh? Sure, why not?

Anyway, another element that sets this lad apart from the familiar is the hulking pair of tyres sitting astride his shoulders. It’s enough to make me sit up and take notice in an Alyssa Edwards’ ‘back rolls’ type moment, except in this case it’s very much a good thing.

I also really like elements such as the smokestack-esque shoulders, including the little flip-round doodads on top even though I’m never 100% sure which orientation they’re supposed to be in for any given mode.

As for the rest of what you observe here? Well, he’s fairly long-of-limb but somehow manages to look quite muscular all the same. They’re not the most conventional proportions on an Optimus toy I’ve ever seen but I think it works for him too. Besides, it’s not like this thing is going to spend much time in a static pose when…





Yes, if it’s not quite evident already, a huge dollop of this lad’s charm is the rather extreme amount of posability on offer! He can twist and turn like very few toys can claim, with some of the resulting poses pushing the boundaries for a design of this kind.

A lot of that is down to the arms, which feature double-hinged elbows but also some extensively articulated shoulders. There are multiple joints going on, including a butterfly motion just to really seal the deal.

Not that the legs are letting the side down, you understand, with the range of motion available at the knees being somewhat unprecedented, as is the way the hips feature two separate joints that allow you to achieve such impressive range.

It’s all enabled in how hip skirts can fold up and rotate around out of the way, leaving a lot of clearance for the legs to do their thing. It’s a very clever solution, even if the skirts themselves do have a slight tendency to pop off occasionally.

Then there are the hands, which might be some of the most intricate and malleable meat hooks I’ve seen in a long time. In truth, I’m not always sold on super-articulated hands but in this case, they’re extremely well done and create quite a bit of extra play value.

That’s to say nothing of *how good* this lad looks once you equip him with his twin blasters. They both clip solidly into his palms and make him look even more badass than he did before!

Alternatively, you can peg them onto the top of his backpack (in two different configurations, actually) for a spot of shoulder-mounted armament instead. I particularly like the way they can then be rotated down onto his back out of the way. Neat touch.

But wait, there’s more! You see, my copy came with two sets of the guns, one of which is in a lighter grey plastic than the other, and you know what that means…


I mean, c’mon!

Ahem, excuse me! Anyway, it’s perhaps not hard to see the appeal of this figure at this point, as honestly so much of the design is geared around making it fun to articulate, pose and display that really, it’s quite hard to put down!

It even has elements such as side-to-side hinge joints in the abs, meaning that there really isn’t much you can’t achieve overall.

Fortunately, all of this is backed up by a solid build, tight joints and quality materials – everything that regular MMC collectors have come to expect from the third party manufacturer.

So, looks fab, great to pose, nicely put together… are there any genuine grumbles to be had here? Er, not many, in all seriousness!

He even has an opening chest compartment with a little Matrix if indeed that’s your pleasure. I initially thought it didn’t fit into the chest particularly well but it transpires that was just user error, so I guess it’s Pexus 1 and Sixo 0 on that score.

You can then set him up to hold the thing in a typical ‘lighting our darkest hour’ pose, although I will say the process of getting the hands wrapped round in just the right way is fiddly beyond belief. Worth it though!

And what else do you want me to say? If you’re in the market for an IDW-styled Orion Pax toy then this thing is on the money. If you like great-looking Optimus Prime toys then this thing is on the money. Hell, if you like *toys* then this thing is on the money.

He doesn’t really have a home in my collection as such, especially as he scales with precisely nothing else I own, but as a one-off? Yeah, I’ll take it.

It’s funny how I picked this thing up on a bit of a whim and now I find myself unable to put him down. Optimal stuff indeed.

WHAT’S HOT? Very nice vehicle mode, fantastic robot mode, simple enough transformation, exceptional articulation.

WHAT’S NOT? The Matrix accessory is a wee bit fiddly.
