“It’s okay!” John said. “It’s only Master Tronic, here to meet us already. See?” “Oh,” Dyfi said, poking her head out. “Sorry, sir. You scared me!” “Think nothing of it,” Master Tronic said. “I’m used to the students not recognizing me at first.” John understood what Master Tronic meant. The technology teacher changed his body to match whatever he was teaching. Right now, he was a lean robot with four tool-tipped arms, which was perfect for teaching electronic maintenance and repair. The only thing that never changed was the red light beam from his head. “So, Galactic Battle team,” said Master Tronic, “are you ready to meet the Defendroids? There are six of them, which is why this team is limited to six students.” He gestured behind him to a large reinforced window, behind which several huge shadowy shapes paced back and forth in near darkness.
