Re: Klingon augment virus/Into Darkness Klingons
There will be no 'smooth-headed' Klingons because the Enterprise episode arc that 'explained' the difference was stupid and pointless. Worf's joke in 'Trials and Tribble-ations' was explanation enough.
Some say that his helmet is bigger on the inside and that his favourite food group is nomex.
All we know is, he's called The Stig.
