The best way to describe Megason would be my "spokesperson". He's not exactly a persona, but more of the one I happen to label on everything. As you can see, this website is plastered with him! ... This exact picture no less! He is surprisingly absent from my stories however, and as a character he is the least practiced by me in role play. There was a time I only had one complete story with him in it (a somewhat piteous comedy the size of a Novella), and the select few who have read the entire thing couldn't help but comment on how incredibly mean he is. I fully acknowledge that he isn't a character one would come to like very easily.
A lot of common role players I know say they had a rather off-impression of him. The pictures make him come off as a your casual nonchalant, and the few times I've used him in roleplay gave the instant impression of a laidback intellectual with enough wit to kill an elephant. He is very much so both at times and they are correct in their presumptions. However, it only shows that I don't advertise his infinite capacity for trickery and sadism enough. When I was in a Role Play room and asked to elaborate on it, I brought him out to give the other present characters a small speech on kindness, virtues, and the importance of sharing.
... misery. The importance of sharing misery.
