Ultraseven Episode 6

Upon returning from investigating a mysterious light source, Dan is called to agent Anne Yuri's quarters after a strange shadow like figure appears there. Claiming to be injured, Dan and Anne sit and talk to the shadow shaped figure, although the alien is equally shadowy about answering questions. Meanwhile, central control receives an alien signal from the planet Pegassa asking that Earth adjust its orbit to avoid a collision that would destroy both the Earth and the Pegassan metropolis. In an effort to avert total annihilation, Commander Manabe orders the city of Pegassa destroyed. But the Pegassas have plans of their own as well. (Source: ultra.fandom)
