Mog Chothra is the main antagonist and a minor character in Broken Age.
Mogs are huge creatures that have visited several villages in the world of Broken Age for almost a century. Every fourteen years, a new one emerges from beyond the Plague Dam to consume the people on the other side. The warrior village of Steel Bunting courageously fought back against the Mogs, but Levina Clench sought a less violent solution. She urged the people of Steel Bunting to give up their warlike ways in favor of becoming a baking town, eventually convincing them that the Mogs will leave their village in peace if they merely receive a few sacrificial girls every fourteen years.
In time, Steel Bunting renamed itself Sugar Bunting and embraced its new culture of baking. Instead of reaching for their weapons every time a Mog was due to appear, they built an elaborate arena for the maidens chosen to be sacrificed. In every village, it was soon seen as a great honor to be eaten by a Mog; the girls would forever be known as heroes that protected their village from a Mog's destruction. This event came to be known as the Maiden's Feast and was treated as a celebration.
Mog Chothra, the latest in a long line of "distinguished" Mogs, visits the town of Meriloft first to collect its sacrificial maidens. Mog Chothra eats every girl except one before moving on to the town of Sugar Bunting. Once there, it eats the sacrifices one at a time until it tries to consume one named Vella. Struggling out of its grip, Vella fights back and manages to escape on a large bird. Levina wails that Vella has doomed the entire village to the Mog's wrath, but to everyone's surprise, it just leaves without destroying anything.
Undeterred, Mog Chothra continues on to the village of Shellmound. Again, it eats the sacrifices until Vella again fights back. This time, she blasts it with a massive death ray she constructed from the remains of the crashed spaceship of Shellmound's Dead Eye God. Shooting its eyes, tentacle-like arms, and finally, a direct hit to its throat, Mog Chothra can't endure anymore and crashes to the ground.
When Vella examines its remains, she's thunderstruck to discover that Mog Chothra isn't a living being at all: it's a giant machine. She's even more astonished when a boy about her age stumbles out. Believing him to be responsible for kidnapping maidens, she throws a punch at him. However, he dodges, and she loses her balance, falling into the belly of the mechanical beast.
Vella is stuck in Mog Chothra, now revealed to actually be a machine disguised on the outside as a monster and inside as the Bassinostra, a space ship. Mog Chothra travels to its home, Loruna, which is revealed to be on the same planet as the other villages, under Marek's command but then exits again when Hope and Vella regain control. It then collides with Alex's ship, where it remains locked until it melts down into a bridge.
