Gundam

RX-78-2 Gundam from the Mobile Suit Gundam 0079 anime

I picked this puzzle on a whim and at least partly because I couldn't make out what it was from the thumbnail. I'm still not entirely sure what I am looking at, a bunch of sci-fi war machines, I suppose. But why is the head of the central figure blacked out? It almost looks like it was deliberately censored, but all the other copies of this image that Google found all have the same black blob instead of a head. Weird.
