"Johann Richter of the Cadian Castellans successfully grabs the Power Sphere! But beware, xenos scum aren't far behind!"
I love WH40k. I love Blood Bowl. How about Blood Bowl 40K?
(and no, I don't mean Mantic's Dreadball smartypants! It's a pity grim and gritty 40k has had all it's humour sucked out of it. Ah well...)
How about some American Football-style team names?
Imperial Guard - The Cadian Castellans!
Space Marines - The Ultramar Saints!
Orks - The Octarius Raiders!
Eldar - The Biel-Tan Broncos!
Dark Eldar - The Commorragh Chargers!
Tau - The D'yanoi Dolphins!
Necrons - The Pavonis Pharoahs!
Tyranids - The Charybdis Kaijus!
Chaos - The Prospero Patriots!

Also: Please excuse the lack of Squats. They would make a great Blood Bowl 40k team though!
