Part 2 of 5. The spectacular mecha crossover continues as Earth and the distant world of Arus are profoundly altered by a mysterious rift in the very fabric of time and space. However, these events were set into motion a generation ago. King Alfor makes a daring endeavor at great personal cost to save the people of Arus, including his young daughter Allura, from a future of enslavement, with or without Voltron. On Earth, Roy must once again face the consequences of personal tragedy and broken promises, and a secretly reconstructed robotic lion may be part of the answer!
