This article is about a/an set of grunts in Power Rangers in Space, the last installment in the Mighty Morphin Power Rangers saga.

The Quantrons are the robotic foot soldiers of Astronema. They are armed with enormous bladed weapons and pilot the Velocifighters. They were seen being destroyed by Zordon's energy wave in "Countdown to Destruction". They come in two color schemes. Black with grey techno designs and grey with black techno designs. Some of them carry a weapon that is similar to the weapon that Klingon's in Star Trek use called the Bat'leth.

Strangely, despite being robots, their armor can be removed and worn as demonstrated by Andros and Zhane in "Dark Specter's Revenge".
