PART 1

America:  

Fear of Criticism–

Ex: In earlier strips, he’s
depicted to be reluctant to show England his movies.

This changes as he later
warms up to showing England his latest movies, only to have it be brutally
ripped apart, again. He’s gotten so used to being criticized by England that he’s normalized it all together.

Perhaps because of these
criticisms, on top of how poorly his movies are rated, is what caused him to
begin “laughing off the negative as something positive.”

Fear of Being Challenged–

He likes to be the #1 at
everything. 

While it’s not made explicit, it’s clear that others’ opinions
threaten him.

Ex: He claims to want to hear
alternative opinions but later refuses to accept them.

Ex: He crushes bundled
spoons, likely as a form of intimidation, to prevent other nations from
disagreeing with his world defense plan.

Fear of Being Alone–

Due to England’s long absences,
he grew lonely.

This translates into adulthood,
where he pesters other nations into hanging out with him.

Ex: He breaks into Japan’s
house + desperately tries to convince himself that at least Japan likes him,
despite all other nations ‘hating’ him.

Discontentment with his
weight–

Ex: He doesn’t like being
called fat.

Ex: He refuses to acknowledge
the ‘number’ on his scale and instead convinces himself that it’s broken.

Austria:

Fear of Being Plain–

Ex: He doesn’t need to wear glasses
but feels simple without them [x].

Canada: 

Fear of Being Ignored/
Forgotten–

Canada was neglected in his
childhood and consequently developed low self-esteem and self-worth.

Ex: He mistakenly believed that
the then colonizing England was looking at
him as a person and not as a resource when they first meet. If anything,
this fleshes out how young Canada wasn’t accustomed to being valued on a
personal level. As such, he doesn’t value himself later on in life.

Ex: He at one point believed
that America was disinterested in him.

Ex: He was once too shy to communicate
with America directly, so he used England as a mouthpiece.

Ex: He cries when Seychelles
remembers that he’s a member of the G8 .

Discontentment with Looks–

Ex: He doesn’t think he’s
good looking.

England:

Fear of being weak + inferior–

Ex: After being conquered
several times over, young England aspired to become strong himself.

Ex: He longs for the golden days of his empire [x].

Ex: He especially feels
inferior when America surpasses him in manufacturing during the Second Industrial
Revolution.

Ex: In “England’s Plan to Be
the Strongest”, England trains to become stronger – an implicit acknowledgment
that he’s lost power.

Low self-esteem–

Ex: As a child, he took France’s teasing
insults to heart and believed that he was “unrefined.”

Ex: While he’s critical of
others, he’s just as critical of himself. He’s self-deprecating.

Fear of Being Alone–

As the “Black Sheep of
Europe, he was constantly isolated from other countries.

Ex: The American Revolution.
