It Was Them

It Was Them is the sixth episode of Ben 10: Omniverse.

Plot
The episode starts with Ben ordering chilli fries while Khyber is spying him with his telescope. When he is about to eat them, Khyber's pet as Slamworm attacks Ben. Ben as Diamondhead defeats it but his lunch is spoiled. In Rook's truck, Ben remarks that more aliens are attacking him nowadays. Then Ben suggests it might be Dr.Animo. So Ben and Rook check up Animo's prison at the Plumbers Headquarters. Animo is missing there while Ben finds a secret tunnel. Rook and Ben enter that tunnel where a giant fire breathing ant confronts them. Ben turns into Echo Echo and manages to surround the Ant and uses Wall of Sound. They find Animo who plans to activate his ray machine which will turn all ants on Earth into mutant ants and he will be their leader. However Rook gets the important pat of the ray and tries to destroy it. Ben tells him to hurry and dials Swampfire but turns into Rath again. Rath defeats three ants but the ants outnumber him. Then he turns into a new alien ' Crashhopper'. Ben easily beats the ants. Khyber's pet suddenly shows up. Ben tells Animo to call his dog off but Animo replies it isnt his. It turns into Mucilator and sticks Crashhopper onto a slimy part of his body. Khyber comes and tries to kill Ben with his sword but Rook saves Ben. Ben destroys Animo's helmet using which he was able to control the ants. Therefore the ants go mad and attack Mucilator. Khyber and Mucilator flee while Animo is arrested again. He swears revenge again.
