User blog comment:Ultimate omnitrix 10,000/Vilgax Must Croak: new episode omniverse/@comment-5846800-20130206021716

The plot might be Vilgax trying to get the Omnitrix, he gets the omnitrix but (1)doesn't know how to use it,  (2)  if ben shows him he's probably not going to like the hologram feature, and (3) the last and final reason the omnitrix has a lockout feature so even if he got it, it wouldn't work for him though Vilgax would figure out something.
