Waaaay back in the 80's my brother and I each got an "Alphabot" toy in the lead-up to Christmas. They were letters that could transform into robots. My parents couldn't find either a Z for me or an A for my brother Alexander, so they got us an N (which I guess looks like a sideways Z) and a B (which is the next closest letter to A). I never really knew what the purpose of them was, but I loved them. Eventually those original two were either lost or sold at a garage sale (against my will), but I never forgot about them. While doing some research on them last year, I discovered that line had been rereleased in Italy! This time the figures came out in blind-bagged packaging and actually had more than one series. The first series was Alphabots Force 2, followed by Alphabots: Mission in the Dark and Alphabots: Mission Galaxy. Alphabots: Mission in the Dark had glow-in-the-dark elements, while Mission Galaxy had transparent parts. I found these right at the end of Alphabots Force 2, so I was only able to get the letter "I" from that line, but I did complete the sets of Mission in the Dark and Mission Galaxy.
