It's amazing the difference between the last Transformers team and the current one. The last team wanted to do a new Perceptor, but original Perceptor was, um, a microscope, so they made him a halftrack truck. Like, you could feel echoes of the plea to marketing for that guy. "LOOK HE HAS WHEELS AND TREADS, HE'S NOT A SCIENCE THING, PLEASE LET US MAKE PERCEPTOR, BOYS DEMO AGED 5-12 WILL BUY THIS."
Meanwhile, the current Transformers team just straight-up remakes the original Perceptor, now with 10% more articulation because the original wasn't too bad about that to begin with. He's a microscope, yo. Again. And by "microscope," we of course mean "Perceptor's robot mode folded up to look like the original Perceptor's microscope mode, which also looked like Perceptor's robot mode folded up and not too much like a microscope." Do kids want this? I'd like to think so, because science is important, but who knows. Here's your regurgitated 1985 Perceptor. Hasbrobadger don't give a shit. Hasbrobadger don't care.
Also he has a third "tank" mode, just like the original, which is rendered on the cardback but not present in the instructions. This is not a great tank mode. It's a terrible tank mode. I mean, they tried, but it just looks awkward and doofy. I can see why they left it out of the instructions. (there are extra tabs and slots for it, plus some extra pieces, so it's not, like, an "oops this toy can still do the original third tank mode" thing, it was definitely intended on purpose)
But, look. Credit where it's due. His microscope still works. It's a functional microscope. The amount of magnification isn't great, but you can even rotate the little nob on the scope and it'll do a small amount of focusing. That's a surprise in 2017. Transformers these days aren't often budgeted individualized gimmicks that aren't part of the line-wide Mega Gimmick. This isn't Armada.
Perceptor's head pops off and transforms into a little dude. His name's Convex.
Also, what I am here for is that this Perceptor is designed specifically after IDW's Perceptor -- at least, the one that featured in All Hail Megatron and beyond, including Last Stand of the Wreckers and More Than Meets The Eye. It probably helped that his IDW comics design is close enough to the original toy that you can do the IDW comics Perceptor and most folks will think, Hey, it's the original style. But the sculpted shapes of the arms and knees and such give him away, if not the fact that he comes with a friggin' sniper rifle. Sadly, he's got two normal eyes, and not a normal eye and a big ol' targeting grid monocle. Also, I guess, the scope is on the wrong shoulder for IDW. The original 1984 toy could switch the scope's placement, but this toy keeps it over his left shoulder, like it was in the cartoon.
If you want a Perceptor that's like the original toy but now he can bend his knees at the hips, this is your toy. Also if you want a toy that'll fit better into your Lost Light display shelf. Or if you just like Headmasters. Or if you're desperate to throw money at something shiny to distract yourself from the rise of fascism, I dunno.
