User blog comment:DeeBradleyBakerFan/If you had an Omnitrix that has 10 of Ben's Aliens, Which Ones?/@comment-4886256-20120310135554/@comment-4551578-20120313011039

Three of those Ultimates don't exist yet. By that, I mean that Ben is yet to evolve those aliens, or yet to have the need for evolving those aliens. One other thing, you wrote "10. Upgrade/Ultimate Upchuck" and that makes no sense.
