There are quite a few. 'Zim's Manifest Doom: The Unfolding' is one. It shows Zim's step - by - step progress towards what he believes is the manifestation of doom for Earth. It has some really cool descriptions of his crazy inventions. 'The Doom That Came from Space' is another good one. In this fan fic, Zim accidentally summons an entity from space that could bring doom to Earth, and Dib has to figure out how to stop it. And 'Manifesting Doom in the Skool' is about Zim causing chaos at school that could lead to a much bigger doom scenario.
Well, I've read 'The End of the World According to Zim' which is a fascinating 'Invader Zim Manifest Doom' fan fic. It's got this great plot where Zim misinterprets some Irken technology and thinks it will bring about the end of Earth in a really strange way. There's also 'Doom in the Suburbs' where Zim's actions in a quiet suburban area lead to all kinds of mayhem and potential doom. And 'Dib's Doomed Adventure' where Dib gets caught up in Zim's latest doom - causing scheme.
Sure. One great 'Invader Zim Manifest Doom' fan fiction is 'The Doom of Dib'. It really delves into the chaos that could potentially unfold in the Invader Zim universe. Another one is 'Zim's Manifest Doom Plan' which has some really interesting takes on how Zim might bring about a sort of doom in his own bumbling yet somewhat effective way. And 'Dib's Resistance Against Doom' shows Dib's attempts to stop whatever doom Zim is cooking up.
