I have read the Ultimate Marvel timeline since I was 17, and I know that the Skrulls (FROM THE ALTERNATE DIMENSION, discovered by Reed, are different THE Ultimate Marvel U, Chitauri). Look the encounter with the Skrulls with Kl'rt was in an alternate universe. Here's a link: http://marvel.wikia.com/Ultimate_Fantastic_Four_Vol_1_28. (  )
