Tho it is a very interesting idea that Empera was the last of his kind, I personally don't think it goes any farther than that.

We already have Yapool and Chaos for multi-being hive-minds of evil, so I'd think Tsuburaya wouldn't have recycled that concept without explicitly stating so.

Then again these days and even back then I wouldn't put it past them.
