Crossovers That Should Not Be 19: Making no sense, right from the gecko

[Seraviel]

I just realized that a specific person was basically a Nanoha character:

-Comes from space.
-Has access to unexplainable, futuristic technology.
-Lost his family in a terrible and mysterious accident when he was young.
-Is named after a car.

Now, what happens if you add Ford Prefect to the cast of Nanoha?

(Apart from the Vogons getting befriended, of course)
-People may die, but ideas are forever. Je suis Charlie.
