Ben 10

S02:E12 - Dr. Animo and the Mutant Ray

Dr.Anino has broken out of jail and, intent on revenge, has been tracking Ben,. At the same time, Ben has broken off a piece of the Omnitrix, and as a result, has turned into weird alien combinations, i.e. StinkArms. When Animo obtains this piece of the watch, he uses it to create a ray that will mutate the entire world--but our heroes stop him before he can execute his nefarious plan.
