Ben 10: 4x2
Divided We Stand
Ben gains another Omnitrix hero to use, which he calls Ditto. Gwen can’t stand being around the multiplying Dittos, and they end up giving her headaches. The Dittos, though, prove to be real helpful against Dr. Animo and his multiplying Stinkflies after he extracted some of Ditto’s DNA.
