The Philfic name Zecta sounds much cooler than his Tfwiki name Zetca or his Tfu.info/Tf2005.com/Transformertoys.co.uk name Zetoca.
According to Tfwiki, '"Zetca" was the name for Takara's line of die-cast miniature Star Wars toys back when the movie first came out in Japan. The name of the "space alloy" those toys were supposedly made from, it appears to be a meaningless, science-fictiony-sounding word.'
So he wasn't named after Brian Blessed's TV series 'Z Cars'.
I have you three down as the most likely suspects: do any of you have any of these?

I like the tiny back of the box art on the box, and much like the Headmaster Warriors, the nearly worthless robot points. A whopping 1/4 robot points. I only know of one other TF product with a lower robot point value.
