the titular cubix is a one of a kind robot built before professor nemo's disappearance, who is found deactivated with no visible damage, but no way to reactivate him either. he is introduced as part of connor's initiation ceremony as the robot he chooses to fix. however, he cannot get cubix to work until dr. k appears to retrieve solex from a robot. connor brings cubix back to life, just as the building they are in starts to crumble. his body is made out of a number of cubes, giving him a versatile modular function- by restructuring himself and using various gadgets within the 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, but often relies on his transformational ability and unorthodox strategies to win. he is powered by a generator that runs off crystallized solex, 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.
