Josef as he appears in Machinarium.
|First appearance||Machinarium (2009)|
Josef is a small, humanoid robot named after Josef Čapek, the Czech artist who created the word "robot". He is friendly and lives in Machinarium, a run-down and decaying city inhabited by robots, with his girlfriend Berta. After being scrapped and dumped into a junkyard, Josef reassembles himself and makes his way back to Machinarium, only to find that an organization called the Black Cap Brotherhood has kidnapped Berta, disabled the city's mayor, and taken over the city, and that they are planning to detonate a bomb to destroy it. It is then up to him to defeat the Black Cap Brotherhood to save the city and its inhabitants.
Josef's defining physical feature is his large domed head that can unhinge with his mouth. By doing this, he is able to place items into it and store an inventory inside him for later use, which he uses to solve environmental puzzles around him. In addition, his segmented body can lengthen upwards or shrink downwards, and he can also extend his arms and legs for additional reach.
Josef is one of the Assist characters in Fraymakers. When called upon, he quickly extends his body straight upward, growing very tall and headbutting any opponents that he hits from below.
