...I've subjected Konrad Reichardt to the Universal Mary Sue Litmus Test. I ran him through as an OC, because regardless of the fact that he is technically a canon character, everything about him that isn't Kevin Ryan is a total ass-pull.
His score: 68
How this measures up:
50+
It's probably a lost cause either way, or you didn't read instructions properly (some people don't do this, which causes freakishly high scores). If it's the latter case, read the instructions and take the test again.
(The instructions are not the problem, lol.)
I don't know why, but I'm inordinately proud of this. It probably isn't every day an ex-Nazi scores so highly on a test like this. They just aren't normally "Sue" material.
Granted, I think any character with an ability like empathic mimicry, even crippled like Konrad's is, is deserving of the title. Beside that, I think the fact that he is basically the McGuffin for the whole fic, related to all the characters, and so closely tied into Company history are the main "problems" (though with Konrad, it's a feature, not a bug). Plus, there's this fun little section in skills where they ask you to check a box for every language your character speaks besides their native one. They could have saved me some time by including a box marked "all of them".
