Robot is an antagonist of the Disney Junior show PJ Masks. He is Armadillain and Romeo's self-created personal servant. His most notable ability is his very long and stretchy arms and legs which are often used to quickly get them from place to place. It is around 3-4 times larger than both Armadillain and Romeo. It is one of the few inventions made by Romeo that has the ability to speak.
The Robot is very respectful and performs tasks for Romeo and brought by Romeo from place-to-place. Similar to how Luna Girl is with her Moths, Romeo tends to mistreat him and acts stubborn towards his warnings about the PJ Masks. It is possible that he is the only friend of Romeo.
