It seems to me that all the new characters created in offical Trek literature end up being pretty well liked by the majority of other characters they interact with.
in the Corps of Engineers books, the Tellarite second officer seemed to start off as pretty unlikable, but that was more to do with him having replaced a popular officer. And even then, he mellowed some and the rest of the characters came to like and respect him.
Likewise with the half Vulcan Leutenant Chen in the recent novel.
Why doesn't anyone take up the challenge of developing a character who the other characters simply do not like?
Better yet, why not create a character that the others start out liking but grow to dislike intensely?
