It's theorized that the 'Acguy' name is the truncation of 'Aqua Guy', guy being used to mean 'unit', which is apt considering that it's a mobile suit for underwater infiltration.
Original Universal Century kits are weird, we all know this and the Acguy is definitely one of the more memorable oddballs. If you want the tacti-cooler version, look up the Gundam Thunderbolt Acguy scene and you might change your mind on this fella.
Aesthetics:
I mean... it's brown. Or rather, it's a satin semi-gloss chocolate brown, which is kind of a rare main color. Along with a bit of grey and tan, it has a simple streamlined look that's meant to be a stealthy underwater unit with thick armor plating.
While it has a stubby look to it, it's a large kit. When its legs are extended, it's quite a bit taller than the classic Gundam and significantly more chunky with some heft to it, comparable to something like the Geara Doga, but even thicker.
Something the kit does that the show rarely did, is portray how menacing some of the goofy looking 'villain of the week' mobile suits are, like the Gogg. They're not just chunky and odd, they're armed to the teeth with some serious heavy firepower, in addition to the 'iron nails' that are as long as the Gundam's chest is deep, such as the four 105mm vulcans built into the head (vs the Gundam's 60mm).
The kit includes a somewhat lackluster sticker decal sheet, but a more interesting sheet of dry-transfers with an 'Akahana' logo, a reference to the 'red nosed' person of the same name in the show and a notable pilot of an Acguy.
Mechanics:
It's a straightforward build with its main features being the eye that runs along the tracks inside of the head, which you pop off to adjust it, and the telescopic limbs.
The latter is somewhat more limited as the legs and arms don't get that much longer, but the interior shoulder and hip sockets can extend out.
If you can't get the hips to extend, you can pop off the panel under its crotch and leverage the two sockets with a slender tool, like a tiny flat screwdriver.
It also has an "action feature" as the claws (iron nails) can be pushed in and by pressing the gun barrel in the center, they pop out around your finger.
While it's by no means a graceful dancer, it is capable of some basic poses, including the cute knee hugging position shown on the product images and in the manual.
Equipment...?
Everything is built into the mobile suit, so instead the kit comes with accessories:
1 unique Display Stand with an adjustable mount that allows the kit to 'swim'
6 Missiles/Torpedoes (lift the panel to pop them out of the arm)
4 transparent underwater launching torpedo effect parts
2 transparent vortex effect parts for attaching under the feet
6 mini-figs - Akahana himself in the pilot's seat, possibly another Akahana carrying explosives (to Jaburo), a diver with a transparent peg for mounting onto the display stand and the three White Base orphan children, Kikka, Letz and Katz on a transparent base, who at ages 4, 6 and 8 find all of the planted explosives on base, gather them up and dump them in a jeep.
Conclusion:
This kit has no right to be this fun. For whatever reason I can't help but just smile and reminisce about watching the original show with some of the most ridiculous characters and designs, but there is a charm to all of it that is completely absent from modern media.
At some point when you have a bunch of Gundams on your shelf, it all starts to look a little repetitive. There is no better way to break that up with your own Acguy.
