For Tropes regarding certain characters, check the [[Characters/{{Madhouse}} Characters]] page.
* AmericaSavesTheDay: Subverted due to the WPA being the leading force against Zerstorung, rather than the US military despite their seeming political power over all the other countries in the world.
* BrainWashed: Done by Melody on several occasions to force Miyoti into doing her bidding, but only once by Zerstorung to deceive Emily into fighting for him.
* CainAndAbel: Zerstorung and Melody are brother and sister.
* DeathIsCheap: Thanks to the technology that allowed RED and BLU to go at it with the same mercenaries for so long, death isn't a concern for the WPA [[KilledOffForReal unless it's Zerstorung dealing the deaths]].
* DuelToTheDeath: Miyoti Sr. finally meets with Zerstorung at the occupied Reichstag, [[spoiler: only to die by his hand, but don't worry, [[YouKilledMyFather his son]] is supposed to attempt the same thing.]]
* TheMultiverse: [[spoiler:When Zerstorung opens the portal to the Pokemon universe, made easily accessible due to the Engineer's teleporter incident.]]
* WarIsHell: Practically the entire premise of the story.
