Fascinating pic of the famous Konami Vic Viper rendered in Lego form.
Back in 1985, I constructed a cool mecha armored suit with an interesting five-colored scheme based off of some mecha suit designs from classic anime series like Super Dimensional Century Orguss, Machine Soldier Dorvack and Super Dimensional Fortress Macross. A couple of years later, built an all-white colored mecha sidekick to accompany it as well. They both have been further customized with Japanese mecha model kit decals for more interesting detail and workmanship, making it a very unique one-of-kind Lego mecha model paired set. It's just a matter of best trying to use the current Lego bricks that you've got to make an interesting piece (or even a kick-ass diorama to accompany them). To add even more realism, I added an internal Lego light brick with wired battery box to illuminate a twin machine gun optional accessory to the mecha suit. (This concept of back-lit weaponry was taken from the cool Gunze-Sangyo produced Powered Armored mecha suit plastic model kits that hail from the Dorvack anime series with their 100% working mini wheat bulbs to illuminate their exotic weaponry back in 1984.)

Even the Lego site doesn't seem to sell them whatsoever. You could say that it's "downtime for repairs" senario. If said blue roof Lego pieces could be sourced, then the right side rocket booster unit and arm could be finished quickly.)

What you see now is the final result after a few minor revisions/upgrades over the years. Originally, it had a twin machine gun attachment in lieu of the right-side arm that was backlit to highlight the barrels and muzzles in total darkness. Even has some cool SDF Macross, GC Mospeada & SDC Orguss model kit decals complete with "wear 'n' tear" weathering on it for extra detailing/realism.)
Since I'm a pinball fan, I did end up making a small Lego brick pinball table with real working flippers. Part of the techincal challenge was trying to construct the flippers and push buttons to make it all work flawlessly. It was an interesting learning experience in constructing it nevertheless using the old-school Expert Builder and Technic Lego produced parts that I had on-hand. It sure would be nice if Lego were to release a fully workng Technic-based pinball table set with jet bumpers and pull back plunger but they haven't done so yet.
Of course, back in the late 1970s-early 1980s, Lego bricks weren't as specialized as they are nowdays. As withs some Lego sets, some Lego piece are exclusive to that particular set...so if you miss it, that's it. There is the Lego.com site with a page that you can order certain speciality pieces if you so desire.
You might recall when Lego first delved into the Space Legoland sets with their kick-ass Galaxy Space Cruiser set, the Mobile Tracking Station, Starfleet Voyager, etc back in the early 1980s. The inspiration in constructing those classic Space Legoland sets was easy to see with the influence of George Lucas' Star Wars films and other sci-fi films in general. Even the "Robot Jox" film was neat with it's realistic armored mecha suit portrayals.
The Expert Builder (later renamed Techinic) sets that debuted back in 1980 were cool as well. Even the Lego Expert Builder Idea books go for some serious $$$ these days due to them being out of print. Of course Lego never reprints them, hence they're quite valuable for their interesting ideas & suggestions to build such working models such as a 100% working clock and a multi-colored graph chart machine (that's completely programmable with a mechanical rotating gear interface unit). This was back in the days before Lego came up with their robotic Mindstorm sets. The latest Mindstorm set is at Mindstorm 2.0.
Lego Factoid: The mecha god designer, Shoji Kawamori, has said that he uses Lego bricks to create his latest fully transformable mecha models (rather than using 100% hand-built wood-based models like with his classic Macross Variable Fighter mecha). I can see the reasoning behind this as it is easier to construct a 100% working prototype with Lego bricks by trial and error and then make a prelimenary plastic based model sculpt to get the finer details worked out (before creating the final production mass produced toy or model kit for general consumption worldwide). Even the classic anime series known as Genesis Climber Mospeada's (aka the third story arc in Harmony Gold's Robotech saga) unique mecha designs was done by Kawamori-san.
