Mostly orienting towards characters who go against clichés at the moment. Been reading a bit of TV Tropes, lately, so I've got a few things in mind:
1. A hacker/cracker who compulsively overdresses and over-grooms, insisting on keeping his appearance absolutely perfect. He's so straight-laced, looking at him is almost suffocating. Think Roger Smith with Radical Edward's skills. Somehow manages to fix himself up almost immediately after any action sequence. Takes advantage of the 'coding in their underwear' stereotype to avoid suspicion.
2. A Chessmaster who prefers Go. Why? Well, did you see that story about how some programmers "solved" checkers? He took it to the next logical step.
3. A benign Virus / Hive Mind that only assimilates the willing and has a good pension plan.
I'll add more if I remember some.
