The third installment of “Lower Decks” features an interesting new twist on the opening sequence: More recognizable bad guys to run away from. In previous seasons, Cerritos flew away from a Borg/Romulan brawl. In season 3, the ship is currently on the run from the Pakled ships (Pakled reprises his villainous roles throughout “Lower Decks”) as well as another familiar face. Er, invisible lattice system.
The Crystalline entity specifically appeared in two episodes of “Star Trek: The Next Generation”. Its level of intelligence is unknown, as the Enterprise never learned to communicate with it, but it is incredibly powerful and destructive. It feeds itself by eating living organic matter due to planetary loads. It is not the presence of an evil person like an uncontrolled animal. Think of a much larger version of the flying saucer from Jordan Peele’s “Nope”.
In his first appearance, “Datalore” (January 18, 1988), Data’s evil twin Lore (Brent Spiner) was able to communicate with the Entity and lure it to a residential area where the Entity was located. Lore happily feeds. Lore’s next plan is to raise the Enterprise for his new ally/pet. Android’s relationship with the Crystalline Entity is strangely intense and has never been fully explained; Perhaps Lore admired another non-organic life-form like herself, and harbored a secret resentment towards her fleshly ancestors. Trekkies knew Lore was a psycho (he threatened to vaporize Wesley with a phaser) and his emotions were never properly balanced by his creator. The insensitive data is built later and is a more refined model.
