Sleuth

Sleuth was a Geth commander who had been given tactical upgrades allowing him to more easily simulate the actions of certain biological species. These upgrades were developed by the Geth Military and were given to Sleuth after he showed prowess in the Morning War. After the overhaul Sleuth became massively more agile and gained the ability to turn Invisible briefly.

Sleuth was given his name by the Quarians, due to his stealthy abilities but on the battlefield and in ship-to-ship combat. After the Morning War Sleuth was tasked with defending the Geth borders whilst also being given special ops missions that allowed him to utilise his newfound abilities.

After his successes in combat Sleuth was promoted to Prime, and gained control over a small fleet. He became one of the forefront Generals of the League and it was at this point that he officially adopted the name Sleuth for his own use. He worked in Geth weapons testing for a time and was able to reconfigure his abilities so other Geth could adopt them too, and soon there were several 'Sleuth Units' in operation, but none achieved the rank or fame of Sleuth himself.
