Hello, All.
Wow, what a topic!
I don't know why, but for some reason I remembered the small plastic "robots" that I used to play with when I was a little kid growing up in Russia. After a short period of time searching Google in both Russian and English, I came across this topic. I'm sure there are some of these "robots" left at my parents house. Maybe I'll make some pictures of them some time and post them here.
Now, to answer some of your questions (and of course, to create more):
1. I'm very surprised to see a vehicle for the Battle Beast alikes. I've never owned one and I've never seen any of my childhood friends having one.
2. From what I understand, the Battle Beast alikes were indeed a cheap copies of the real Battle Beasts. As I recall, all the skeleton figures and other more cool looking figures started to emerge later on. The "Battle Beasts" or how rotr correctly said "robots" were the first ones.
3. The first time I saw a "robot" was in 1990. There was a kid not from my neighborhood playing outside my house. I noticed he had very colorful toys compared to the usual blunt soviet plastic toys. I approached him and he showed me the "Pig" and the "Giraffe". I never asked the kid where he got the toys from. From that day on, I bugged my parents to buy me those, too. However, they were no where to be found, until my dad picked up a "robot" from a "street market" on one of the train stops in a suburb of Moscow. He brought it in and asked if that was what I was talking about and it was it.
4. In a matter of maybe a few months, "robots" began to be sold almost everywhere. Let me explain. In the soviet era, all the products (including toys) that were sold were controlled by the government. About the time when the soviet union collapsed, people started to go abroad, purchase things there, bring them back to Russia and sell them on streets. These "street sellers" were the source of "robots". My best guess is that "robots" came from China, where they were copied off Battle Beasts...
5. "Robots" had no packages and even later ones didn't have packages either. They have no marks on them, not even the "Made in..." writing. Robots were made of 3 parts: the center piece and 2 arms. Since whoever manufactured them gave no crap about what arms go with what body, it resulted in many "combinations" of "different" robots. For example, I had 2 wolfs. One had two "fish" arms and the other one had the kind of arms where the left arm was a hook.
6. "Robots" were the coolest ever toy until transformers were introduced some time later. Of course, transformers were also a cheap copy of the originals... but that would be a separate topic.
Maybe I'll write some more memories if I'll remember something... actually, I wanna go to my parents house now and dig up some of my "robots". I only got a handful left of them, since I moved from Russia a while ago and of course did not take all my toys with me.
Hope this shines some light on some of your questions.
Cheers!
P.S. Oh! One more thing. From my point #3, I've never seen a pig robot again back than. They seemed to come out in waives. So, this month all street sellers would have a fish and a wolf. And the next month they would have a bird and a lizard, but the wolf and the fish would never return again.
