Ben 10 has more than ten aliens while protecting the earth.

ben 10 aliens unleashed or ben 10 evolution
It is assumed he doesn't, as the new aliens are "fusions" of the aliens from the original series.
The Omnitrix (the watch-like device he uses to transform into an alien) has 10 aliens at time. But it happened that Ben managed to "unlock" more aliens by collecting their DNA.
A list all the aliens ben has
10
63 aliens.
None of them has all the aliens
