If you have a shield, go to the second planet. Put on your shield and go to the Sumos. They will make rapping noises and not be able to attack you.

• Defeating Otto Destruct
To defeat Otto (the final Boss), you need four weapons: The Optical Maser Array, Electro Rocket (with Shock and Lock-on mods), Shield Barrier, and the PDA. Put up a shield and use the Optical Maser Array to lower his shield. Then, shoot him with the Electro Rocket. Keep repeating this until he is defeated. Use the PDA if you run out of ammunition. Note: This is when you and Otto are the same size, not for the Battle Ratchets, Giant Otto, or the Giant Clank Battle.
