Space Battleship Yamato Season 2 Episode 3

Earth's Endangerment Awakens Yamato!

Wildstar and Nova visit the remains of one of the underground cities that Earth used when it had been devastated by Gamilon radiation. Wildstar fears that the new threat could make them necessary again, and knows the the EDF government will not act quickly enough. The encoded message received during the power surge is analysed and determined to be a jammed distress call from outside the solar system -- originating somewhere in the same area as the approaching comet (the issue of it being in some "unknown language" seems to have gone away). But the Earth Defense Committee refuses to take action or to take the possibility of a new threat seriously. Wildstar assembles the old Star Force crew in front of Captain Avatar's memorial statue (Heroes' Hill), and proposes a renegade mission to seek out the new threat.
