At the start of the series, he is broken and no one can figure out how to make him work. Connor then brings Cubix back to life. His body is made out of a number of cubes. He can transform into a hover bike, an airplane, a helicopter and plenty more. He can even fly without the need to transform into a vehicle. Hidden in each cube there is a different gadget with a solution to almost every dire situation. When it comes to fighting, Cubix is exceptionally strong. He is powered by a Solex generator which is rumored to be the ultimate power source, but nobody knows exactly how it works. Cubix's body is also constructed out of a highly resistant metal that is capable of withstanding devastating amounts of damage without breaking. He also has additional parts that when added to his structure can increase his strength.

Cubix is a friendly and helpful robot, but lacks speech capability, while speaking seems to be common place among other robots. Usually he just repeats what people around him say. However, later in the series this improves greatly and he becomes capable of forming sentences and dialogues.
