A member of the eldora five, Carlos seems to be eternally sleep, even during battle. Though he sleeps constantly, the other members bring him along in their armor anyway, saying to others that he's "awake in spirit." He awakens only twice in the series, once after the battle with Bucchi's armor, and the second time during the climactic battle with The Claw, activating their armor's reserve power cell and reminding his comrades that they should have read the manual.
