Hogwarts vs G1 Transformers movie TFS
The wizards have captured the Matrix of leadership.
They no time turners, as its set after book 5, but they do have a prophesy, saying "The eater of worlds is coming, and so are a bunch of alien robots that change form".
No HP or TF EU, although Techspecs are submissible for matters of discussing limits/definitions of TF capability to keep it real...
The Cybertronians know that the Wizards have it and all of the TFs featured in the 1980s animated G1 movie know about it, and where it is. The must destroy the wizards, morals off and destroy Hogwarts, to retrive the Matrix... Autobots and Deceoticons work together alike.
They open a space bridge to Hogwarts and a battle for the Matrix is under way.
Harry Potter Versus G1 Transformers:
"One shall stand....and one shall fall."
Who wins...?
