Mary Sue. Argent and the Wrecking Crew, along with center-of-everything Ryan Mercury, are what turned me off Shadowrun novel fiction, because they're all so blatantly ... I can't say, because this is generally supposed to be a family board.
One of the things -- and to be entirely honest, here's the main thing for me -- you judge a Mary Sue by is 'how do the main protagonists get along with them?' Oh, capabilities/powers is one thing; outlook, another. (BTW, Pollyanna wasn't a 'the world is an incredibly wonderful place!!' kind of girl, she was 'well, let's make the best out of what we have'. She tried to see the good in even the worst situations, and if you'll recall the movie, that didn't always hold her up.) The worst violations, IMO, are those who are automatically friendly to people they've just met, just because those are other PCs.
And yes, we have those on the boards here.
No, going by that mark, I will never, ever be in danger of playing a Mary Sue. A character is measured by their abilities; a good character is measured by their opposition. A great character is measured by their interaction with other PCs.
