Sydney is a villain in Ben 10. He appeared in the episode The Filth.


Sydney looks like a tall human with a cockroach head. He has black eyes, antenna, maxillary palpuses, and labial palpuses. He wore an orange suit with black gloves and the black radiation sign on the left side of the chest.


Sydney shares the same taste of filth as Maurice. He is intelligent, since he is able to drive a vehicle despite having the head of a flea.

Powers and Abilities

Sydney has great strength. He's also good at digging as seen in Max to the Max. He is able to spit a green drool from his mouth to defend himself. Because of his flea head, he can eat things at a great speed. In addition, he is intelligent enough to drive a truck despite having the head of a flea.


In his debut The Filth he took orders from Maurice to build the Magg-O-Net Monster.

In Bad Penny, Maurice created a helium weapon in attempt to steal the bank with Sydney, but Diamondhead used diamonds to weigh down everything and Maurice got arrested with Sydney.

In Max to the Max, he and Maurice dug up into the forest and found Ben. Maurice wanted to duplicate Four Arms to do less diggings, but accidentally duplicated Max instead.
