In Bubble Town there are robots of all shapes and kinds, even one of a kind test model robots. Humans and robots have lived and worked together in harmony, until now... suddenly robots have been battling each other and no one knows why! Connor has to fix a robot in less than 24 hours to join a special club for kids who can fix robots called 'The Botties'. Connor picks Cubix, a one of a kind test model which the Botties all call Cubix the 'Unfixable Robot'. Connor fixes Cubix.

After a sudden attack by Dr. K, an old colleague of Professor Nemo, who runs off with a stolen robot, the Botties' pit begins to crumble. But because of Connor's talent and thoughts projected into EPU of Cubix, he is brought back to life. Cubix then saves Connor from the collapse. Proving once and for all, that Connor could even fix the 'Unfixable Robot'.

Now operational, it's not long before the mighty powers of CUBIX are put to the test. CUBIX stands up to evil & crazy robots and reveals a series of startling powers. Though normally playful and fun loving, Cubix will go to any length to protect his friends.
