All Autobots assembled at a lunar base, Earth suspended in the starry sky behind them, Cybertronian flag flying proudly. Create an epic wide-angle composition showing the full roster of Autobot characters in heroic poses on the lunar surface, with detailed mech designs, dramatic lighting from Earth's glow, and a sense of unity and determination. Include recognizable characters like Optimus Prime at the center, with the lunar landscape and space environment rendered in cinematic detail.
