Munchon
From Jenny Everywhere Wiki
In one universe, in the 1960s, after Captain Stewart asked Jenny Cornelius to create a distraction so they could slip away unnoticed, she achieved it by rousing a giant atomic sea monster. After emerging from the Sea of Japan, it “stormed through the outskirts of the harbour city of Munchon”, before heading west into the mountains, seemingly making for the city of Pyongyang which it was projected to reach within a day or two.
