Do you think Ghostfreak's DNA sample isn't linked to Zs'Skayr in Omniverse because the Second Omnitrix stores DNA in computerized form instead of using physical Ectonurite DNA?
I was thinking the same way. The DNA is in fact artificial so it would only make sense. But then again, Ghostfreak's sample in the Ultimatrix did not make him lose control despite being connected to the Condon Stream.
