Shere Khan is the head of a multi-billion worth company named "Khan Industries". In the series, he's almost always represented behind his desk, at the very top of the Khan Industries building.
He appears as a very cold person, always serious and with no sense of humor. (well, like most company heads, not very surprising...) Even though he's obviously interested in making money (and he's shown interests in buying Higher for Hire, at least in the comics, as well as Louie's bar), it seems he has other secret interests.
He reckons Baloo as a great pilot, even though he don't always remember his name.
Contrary to its Jungle book character, Shere Khan here isn't a villain but acts more like a neutral character - in the series, he helps anyone who can make things more profitable for him, even if it sometimes comes to dealing with air pirates.
