I was just thinking about anime related stuff that we have seen prototypes for but never made it to production. What figures out there never made it past prototype that you wish could be resurrected? For me a big on is Saint Seiya from Legend of Sanctuary.
Great idea for a thread! I remember Square Enix was going to release their 1/4 Sephiroth, but never did. A prototype of him could be seen at conventions too.
Bandai was going to make a line of S.I.C. inspired Thundercats when they had the license for the last show on Cartoon Network. Ando was even designing them.
