Which Melee top players have given themselves over to the dark side?

During top doubles at Eden today, the commentators brought up how some players are more "light side" or "dark side". It was merely a part of the banter, but, just for fun, I wanted to pose the concept to you all. So, who do you think are the Sith lords of Melee? Any criteria can apply, though I did consider the following when writing this post:

• aggression (in person or play style)
• mercilessness
• trolling
• raw power
• miscellaneous play style factors
• public image
