Now clear this up for me, Do Space Marines have working penises? 'cause they have never really clarified.
But if no working Ultra dicks, how do they buttsecks? 'cause we all know that's what they do in their spare time.
Don't be silly. Ultrasues only have 20 minutes of spare time and spend all of it by worshipping their spiritual liege, Marttheus Calward.
With how the Geneseed works, its customed to males. The only females in the 40k universe are imperial guard or Sisters of battle. Having said that, I don't think they are sticking rigidly to canon.
Nope, no lady Space Marines! Female Chaos marines maybe, as new Chaos Marines are boosted by Chaos, but even that idea pushes the bounds of heresy... No, you'll get Sisters of Battle Female Inquisitors and... Female Imperial Guard "And still a better love story than Twilight!"
Did you know all the other chapters are sad because their Primarchs are inferior to the Ultramarine's spiritual liege?
