Why is the name "Harkonnen" used on Seras' cannon in Hellsing?


After reading an interesting post on the "anti-midian" meaning of Seras'
battle rifle/cannon thing, I would like to know what the motif of Vladimir
Harkonnen from the "Dune" series has to do with her cannon?

Let me give you an example:

> Alucard's awesome pistol "The Jackal" symbolizes Walter's future betrayal of
> Alucard because, in the Fred Forsyth book "The Day of The Jackal", the
> character The Jackal kills everyone who helped him make his forged documents
> and weapon as a way of covering his tracks as he tries to kill Charles De
> Gaulle. In the dream sequence where this motif is introduced, The Jackal
> comments, "Never trust the man who makes your own weapon," which foreshadows
> Walter's betrayal.

So since Seras has two huge cannons that bear the Vladimir Harkonnen name and
she even talks to Harkonnen in a trippy dream sequence, what kind of symbolism
or motif does Harkonnen have in relation to the _Hellsing_ universe?




If you recall from the OVA and manga, during dream sequences, the appearance
of the gun's so-called "spirit" bears a strong resemblance to Baron Harkonnen
from the David Lynch adaptation of _Dune_. This is strongly implied to be a
tribute/reference to the _Dune_ series (or at least the movie).
