The Inventor sold robot duplicates to birds and next day, they diassapeared. When Daniel, Tyler and Ryan came to investigate he revealed his plans and set their robot duplicates on them. Our heroes led the robots to the bell tower and trapped them in the bell. They then banged it causing the robots to shatter. The Inventor was sent to prison on another distant island and never seen again.
After Daniel, Tyler and Ryan found out that Hamm had been replaced by a robot for 6 months they went to The Inventor's abandonded factory where The Inventor revealed the previous robots were just prototypes. He then released the upgraded versions on them. After many fails to destroy these robots, Daniel, Tyler and Ryan trap them in a rocket with The Inventor and send them to the moon.
On the moon, The Inventor took apart the rocket and using the parts, he upgraded Robo-Daniel and Robo-Ryan to Mark II or Astro. They came back to the island in secret and continued their masterplan. Robo-Daniel was used to hack into the island website making The Inventor practically own the island. He and Robo-Ryan started upgrading birds into robots and later with the new robot birds made a robot duplicate of The Inventor in secret from The Inventor. The Inventor was abandoned and the Robo-Inventor caused more chaos. Robo- Daniel bcame the main security system. Later, listening to Robo-Tyler, Robo-Daniel and Robo-Ryan became good and they all self-destructed in the middle of the factory, sending out sonic waves destroying all robots. Feeling sorry for The Inventor, Daniel helped him to create Robo-Daniel,Tyler and Ryan.
