Solidifying Kroton Forms

Bubbling vats in the Dynatrope control room hold a thick, crystalline slurry that accelerates into solid, ominous shapes—the emerging Krotons. The Doctor and Zoe watch as their captured mental energy powers a thermal switch, speeding the process. Jagged crystals harden amid the roiling liquid, their formation visible through the vats' transparent sides. The Doctor reacts with alarm, seizing Zoe's arm to flee before completion.

S6E20 · The Krotons Part 2
Doctor and Zoe discover Kroton forced labor

The Solidifying Kroton Forms within the vats are the most ominous revelation of this event. As the Doctor and Zoe observe, jagged crystals begin to harden in the slurry, signaling the Krotons' forced rebirth through the stolen mental energy. This process is both a clue—revealing the Krotons' vulnerability during crystallization—and a threat, as the Doctor realizes they must escape before the process completes. The emerging forms embody the Krotons' exploitation of the Gonds and their captives, making them a symbol of the oppressive cycle that must be broken.

Before: Liquid and formless, the slurry begins to bubble as the mental energy transfer initiates the crystallization process.
After: Partially solidified, with jagged crystalline shapes visible within the slurry, accelerating toward completion.

S6E20 · The Krotons Part 2
Doctor realizes Kroton transformation threat

The Solidifying Kroton Forms are the ominous, jagged crystalline shapes emerging within the bubbling slurry of the vats. The Doctor and Zoe witness their formation, realizing that these shapes are the Krotons themselves, solidifying through the stolen mental energy. The sight of these forms accelerates the Doctor's decision to escape, as he understands the immediate threat they pose.

Before: Partially formed within the slurry, their solidification process accelerated by the mental energy transfer.
After: More defined and solid, though not yet fully formed, as the Doctor and Zoe prepare to flee.
