Robots are disappearing in Bubble Town, but the Botties are on the case! The Botties think Dr. K is responsible, but when Dondon narrowly escapes being disintegrated by Disposix, he knows otherwise. Unfortunately, Dondon's voice module gets broken in the attack and leaves him speechless. Finally, Disposix's Solex becomes too unstable not to notice and, of course, Dr. K shows up to collect it. Knowing he'll have to put up a fight he brings Kolossal and Katastrophe to ensure his success.

Kilobot, sick of Dr.K's shortcomings strikes out on his own and returns to Robix Corp to steal the tools necessary for world domination that K failed to obtain. But it's not as easy as he thought it would be and he is forced to impersonate Maximix to get the job done.

It's up to Connor, the rest of the Botties, and surprisingly Dr. K to restore Cubix, Maximix, ward off the zombot army, prevent all of Bubble Town's robots from Kilobot's evil brainwashing and beat him once and for all!
