Husk

Husks are synthetic zombies created by the geth. When a human is captured they are placed on a impaling device, they are impaled and killed. In a short time of 30 minutes their organs and skin are removed nothing remains but flesh and muscle. The machine automatically converts their body to conduct electricity and turn them into a machine, at this point the Husk no longer resembles what it used to be. They are realeased to do manual labor or for offense, they attack by charging at their enemies and giving off a powerful electric blast.

Husks are encountered early in the game on Eden Prime and at the end on the Citadel.
