Yeah, now I remember you. You were the obnoxious, manipulative, picked-last kid I used to play with the Doom multiplayer : )

I would also add two more "species" of toxic individuals:
11. Righteous cowards
Individuals with inflated sense of so-called morality who always preach about doing "the right thing" and criticize others' actions or decisions. However, when it comes to making actual decisions and taking responsibility for those decisions those people would rather hide behind other's back and delegate the responsibility. Sometimes I have a feeling that those individuals evolve from "teacher's pets" types.
12. Asocials
They little bit different from lone wolves. They don't have problems with talking about their work or sharing it with others. However, they do not feel comfortable being in a group. Simply because they don't know how to fit in and meet social demands of a work environment.

I dealt with both types of people, and, frankly, avoid the righteous cowards as much as possible. They can be quite smart and productive, but at the end the disadvantages of working with them far outweighs the advantages.
