Dr. Jekyll and his non-to-friendly alter ego...

Here's an idea for a role-playing character I'm dabbling with (he'll probably be quite difficult to play, but...):

Dr. Jekyll is a nice man. The friendly neighbour type. If you met him on the street you'd probably stop and chat for a while. "It's a beautiful day, isn't it." "Oh, quite, let's hope lasts..."
Dr. Jekyll enjoys reading the morning paper, drinking his coffee - in a few minutes he's completely zen. He reads about murder, death and generel mayhem - and thanks God he is nowhere near all of that!

Life, it appears, does have a sense of humour...

At night, having transformed into the dreaded Mr. Hyde, he roams the streets leaving terror and destruction in his wake. Why? In an attempt to improve the capacity of the human body Dr. Jekyll has been conducting numerous medical experiments on himself (and his pet dog Spot) - and let's just say that the project was neither a complete succes or failure...

Dr. Jekyll's stats are:
Human
Mad Doctor
Therapeutics doctorate
CH should be around 9-11
His alignment should stay around 0

And he should always keep a wide selection of physically enhancing drugs...

I haven't worked the rest of the details out yet. He could be fun, though...
