Mathra's Revenge is a chapter in When the Cold Breeze Blows Away. In this chapter, during the USRAC War, Su Ji-Hoon, the Preschool Girls, Team Magic School Bus, Team Chloe's Closet, the Little Einsteins, the ClueFinders, Monarch, Mystery Inc.]], the Pan Pacific Defense Corps, the United Nations peacekepers, the United States Army and the combined troops of the Grand Alliance, including all of his friends, travel to the Numerian rainfroest and Dr. Horace Pythagoras.

Soon, they travel to a great city that was once built 1000 years ago in the Numerian rainforest, until a monster named Mathra invaded, and after capturing this monster, the Numerians abandoned it and sealed the entrance and hid the two halves of the key in the far corners of the rainforest - one in the Monkey Kingdom and the latter in the Goo Lagoon.

Soon, animals have started to disappear in the rainforest once again, along with Joni's uncle Dr. Pythagoras. Mr. Limburger flies the ClueFinders in his airplane and briefs them on the events going on. The ClueFinders set off to find the lost doctor, animals and the keys to the Lost Numerian City. Evidence that they find, however suggests that there is more to those disappearances than the 1000 year old monster as well as a sinister plot behind it.

As the chapter progresses, it was learned that Mathra is now free to service for the Coalition of the Red Star, including the Empire of the Rising Sun and the Unified Soviet Red Assault Command, then the Grand Alliance began to slay Mathra once and for all.

At the end of the chapter, descendants of the Numerian people were learned to be of the Numerian blood, then they soon reclaimed the Lost Numerian City as New Numeria, just as it eventually becomes a modernized metropolis, then Numeria is now an independent country.
