Black Spathi Squadron
A legendary band of Spathi who overcame their race's natural cowardly nature and dedicated themselves to "performing brave and hostile deeds". They painted their ships black with bright red stripes in order to distinguish themselves from the normal cowardly Spathi.
No one knows if they actually existed however, and the Spathi themselves have never mentioned them.
The Black Spathi have a following among the Star Control fanbase. The Pages of Now and Forever contain a page on Black Spathi History (written by fans), and a ship is available in Aftermath known as the Black Spathi Stalker.
