So, about the whole Prussia situation: since nothing is
confirmed in canon, I’m going to keep coming up with possible theories and
explanations. All of which, in my opinion, make some sort of sense. This time,
I’ll be presenting evidence that suggests that Prussia is neither dying, a
nation, nor quite a human.

In “It’s a treasure box of countries”, we’re given a
goldmine of information with regards to the rules of nationhood. We learn that NikoNiko,
a human who achieved micro-nation status, went back to being a regular citizen
and human. It’s also stated that it was difficult for NikoNiko to revert back
to being a human, despite resuming normal aging again.

However, the last two bits of information are crucial.
First, we learn that when a nation’s culture or personality dies, said nation
in question will fade; that or the nation entrusts themselves to their
successor. That’s what most people, including myself, have speculated about
Prussia’s fading status as the personification of East Germany.

On the other hand, Hima also drops this last little bomb on
us.

Yes! It’s possible for the ex-nations to become political
representatives, as opposed to personifications. What’s more, we’ve seen
Prussia attend world meetings with Germany. For example, in the strip titled
“Germany’s Playing an Impossible Game”, Prussia is seen attending an EU
meeting.

Further, I think this may be a typo on the translator’s
part, but Prussia at the end of the strip states:

For the sake of this post, I’ll be making the assumption
that he actually said, “the wall in our hearts.” Why? Because we’ve already
seen with Sealand that the nation’s landmasses are reflected in their physical
bodies. What I mean by this is that because Sealand’s landmass is a minuscule
fort, being a nation would be hard on his heart.

Simply put, it would seem the hearts Prussia is referring to
relates back to German Reunification following the fall of the Berlin Wall. Yes,
we get it, it’s very heavily implied that he’s East Germany (especially with that nostalgia pun, geez). Just call him it already, damn it! Enough with these
roundabout East and West nicknames.

Anyways, why do I think Prussia’s a representative then?
Well, aside from the fact that he’s attending world meetings, we’ve seen in the
“Private Concert” strip that he doesn’t heal from his injuries quite as fast as
a regular nation would.

Is he a nation? Probably not.

Is he a human? Not sure.

Is he a representative?

At the very least, he sure seems to be.
