The real life rx-78 gundam was a statue made for celebrating the 30th Anniversary. All this one could do is stand there and light up. there are not many pictures of this one out there right now because of the newer rx-78
so at gundam central they felt the decor was a little bland so they made this the unicorn gundam. this was way before the rx-78 was made. so unlike the newer rx-78 all this one could do is light up and have the panel plates move. like the anime when it was transforming.
During coronatine the production of the gundam anime was halted since there would be so many people near each other. So bandai got some engineers together and they were making a real life working gundam that can walk and move. it was named the real life rx-78 ver.2 as there was already a rx-78 made just did do anything. also the name is not to be confused with the rx-78-2 of what is a totally different gundam
The RX-78 Ver.1
The Unicorn Gundam
The RX-78 Ver.2
