Metropolis ending explained (spoilers)

[Michaelascet]

Tima sits on the throne of the ziggurat after she's shot by Rock and initiates an attack on the city. Rock activates the super weapon (connected to Tima) when Duke Red is threatened by the robot workers and the place starts to collapse because of the overload caused by Tima's connection to the ziggurat throne. Kenichi pulls Tima away from the throne of the ziggurat. As the ziggurat collapses, Kenichi tries to save Tima as she's dangling from the edge and she falls. The city now in ruins, Kenichi decides to stay, Detective Shunsaku (Kenichi's uncle) leaves and some robots gather some of Tima's parts. The final scene is Tima's voice on a radio, indicating that she's still alive...
