Rossi

Dr. Rossi was an Italian scientist in the 1970s. When a space probe brought back samples of dust which had originated from the planet Sequiz, he was brought in by UNIT to study the samples in a lab based in Black Peak. When he exposed the dust to ultraviolet light, it began moving by itself, emitting a high-pitched singing noise and forming into a distinct shape. Dr. Rossi was very excited, but the Brigadier, recognizing the potential danger, shut down the experiment until he could bring in the Doctor, much to Rossi's dismay. Before the Doctor could arrive, agents of a foreign power broke into the lab, abducted Dr. Rossi and stole the sample, taking them to their base in the far north so he could continue his experiments. The Doctor and the Brigadier tracked them down, but Rossi activated his ultraviolet machine to full power, enabling the dust to reach its final, monstrous shape. The Doctor saved Rossi's life when he battled the creature, forcing it to go back to Sequiz. (DWA: Caught in the Web)
