Inom TV-kanonen fanns det bara en kristallin enhet (t.ex. den som ses i episoderna Datalore och Silicon Avatar ). Det finns flera rader i det andra avsnittet som bekräftar att det är samma varelse som i det första:
DATA: Trace elements confirm that it was the same entity which destroyed the colony on Omicron Theta.
Besättningen gör det också ganska klart att det är till skillnad från vad federationen har stött på tidigare.
DATA :... confirmed by Lore's report to be an unknown kind of creature, capable of stripping all life from an entire world...
och
GEORDI : It's like a snowflake crystal, sir. But much more complex... I haven't the slightest idea what it is, sir.
Förflyttning längre ner i kanonskalan ser vi många kristallina enheter i Trek-novellen Orions hundar .
Troi turned to Oderi, who was back on her feet and consulting the status-display band she wore about her wrist. “What is it? What’s going on.”
“The station is under attack by branchers.”
“Branchers?”
“A very, very deadly form of starbeast. Huge living crystals. They fire beams that disintegrate living matter and absorb its bio-energy. They—”
“Oh, my God. Can you show me an image?”
Oderi nodded and tweaked her status band to project a small hologram of the scene outside the station. Deanna gasped at the sight of the familiar, ramified blue forms closing in on their position. They were the same kind of Crystalline Entity that had destroyed Data’s homeworld decades ago.
And there were three of them.
Det finns också en mycket större modell som ses i Star Trek Online-avsnittet " Den kristallina katastrofen ". Det tar ungefär tio suveränsklassfartyg att döda det.
