Opening
The opening shows all the aliens Ben has ever turned into and the Ben 10,000 aliens, but Dwayne McDuffie has stated that not all of them are unlocked on Ben's current playlist as some think. In the background there are also clips that show some scenes from Alien Force and some from Ultimate Alien. Eon is not present due to the fact that his DNA is no longer in the Codon Stream.
