"Cool! now I can fuck twin hot bansheed!" anonymous spacebanshee pilot
"Let's call it the most generic name EVER!"
Douche Truth naming it.
The Space Banshee is obviously a Banshee for space. It was invented when the Covenant FINALLY found out that they suck dick and nobody cares about them. They where getting sick of their space whales that were named after fucking cars, so they invented the piece of shit known as a Space Banshee.
