If you like FMA and are even slightly aware of Harry Potter, i suggest this fic: Snipers solve 99% of all problems

Amazingly funny, well blended fic

The two worlds seem to be in different dimensions but no one in fic has worked that out yet, as far as i can tell

They can understand each other thanks to glorified google translate rocks, which has led to some amazing misunderstandings

Harry Potter -> hairy potter -> furry ceramics professional

For example

And the slow upticking of the Amestrian's reaction to the situation is glorious, as is the slow reaction of the Wizards going wtf to everything
