However, I'm not saying Alien X is bad, because Ben hits the omnitrix too hard, thus randomizing the selected transformation, so there's only a 1 in 62 chance of him becoming Alien X. However, for ultimates, there's a 12 in 62 chance of Ben getting an alien that can go ultimate, so I highly doubt they would add the evolutionary function again. Also, like most people that hate on Omniverse, I disliked the design at first, but it soon grew on me and in my opninion, is the best of all the series, mostly because of the childish design xD.

Every alien can go ultimate.
