Appearently every character has abs.
Doesn't matter if they don't actually have them in canon.
THEY HAVE ABS.

Armin? FUCKING ABS.

Italy and Romano? MORE FUCKING ABS

Some character who's actually pretty weak, and not physically strong: EVEN MORE FUCKING ABS.

Damn god must be pretty generous because he's basically pulling an Opera Winfrey move.
"YOU GET ABS, YOU GET ABS, EVERYBODY GETS ABS!!!!!!"

I feel like I already talked about this, but whatever.
