S18E5 · Meglos Part 1 graph

Meglos transforms Earthling into his new form

Meglos completes his grotesque plan by feeding the Earthling prisoner through a destructive transformation process that merges flesh with his sentient cactus body. As energy pulses electrify both bodies in separate alcoves, the Earthling’s skin blackens while megas’ cactus form shrinks and weakens. The new composite entity emerges with spined green flesh, a monstrous hybrid of the mercenary and the villain. The moment cements Meglos’ ruthless cunning—using proxies to manipulate the Doctor and Tigellans alike—while trapping Grugger and Brotadac as part of his long con, proving no one escapes his scheme on Zolfa-Thura.
