Tanker-Builder
Okay!
Will somebody educate this old man? I know what Transformers are, My first little boy loved them. Now, I do have some Maschinen Kreiger figures. I kinda like them. But these things with blades and angles sticking out all over. What are they? Robots? If so, Why don't they look like robots instead of super fragile assemblages of what seems disassociated parts?
That's a big question, and can take a lot to answer in full. I'll let others with a bit more time weigh in, but, in brief: Mobile Suit Gundam started as a manga/anime property, much like Macross, Robotech, Starblazers, and the like. A Gundam is an enormous mobile suit--think a humanoid-shaped tank that can also fly and travel in space. While there are differenent classes/types/versions, Gundams are often bipedal, have arms and heads, and sometimes wings. They are driven by pilots.
The models, produced almost exclusively by Bandai now (which owns the property), represent mobile suits seen in the novels/manga/movies/TV series. Bandai's range is, to be frank, enormous, with all sorts of models ranging inscales from 1/144 to 1/48, and varying degrees of difficulty and detail.
Gundam models are one of the largest model markets, popular around the world with modelers of all ages and abilities and is a huge part of Bandai's portfolio, which is, counting all of its pop culture licenses, widely viewed as the single largest producer of plastic models in the world.
