The Golden Star

This is the third Shiny Star SpongeBob rescues. It was being held by Lancer. He used it's ability to increase his power. SpongeBob and co. read the blueprints to his power-sucking machine and he runs away. They meet him in the arena and he becomes Master Lancer. After defeating him, John walks into the office and explains how his brother was sucked into the machine. The Shiny Star reacts to this and brings back the missing fighters. SpongeBob gets the ability, Power Play, allowing him to increase his attack power and defense power.
