Just like Tenma and Saru, Zanakurou is either Zanark's preincarnation or his Ancestor, and maybe the source of his SSC-worthy power. They never explained how Tenma and Saru were related, though. Nor did they ever verify if Zanark- or Tenma, for that matter, were SSC. I mean, most people assume that Zanakurou is Zanark (for obvious reasons), but there's pretty much only one instance where it's really hinted that they're related in some way.

Not to mention that Zanark could be from any time, since he was criminal that traveled through history as he pleased. Saru was from the future, though, so the idea that he is Tenma isn't really too easy to support (especially when the series doesn't really push the idea other than the fact that they look alike) and the idea that he's related is possible, but considering a certain move that Zanakurou used in one of the final episodes and how it happened, it's unlikely that Saru and Tenma's connection is the same as Zanark and Zanakurou's.
