I had fun with this particular strip. If anyone is wondering, Mystery Inc. was a clan that existed on City of Heroes. They were a role play group that would quest together. It was funny to watch them at work.
If you're wondering, Fred was a Tank, Shaggy and Scooby were Scrappers (fighters), Daphne was a defender (ranged/support), and Velma was a controller (magic/support). Now imagine them running around the city and solving crimes with superpowers and spouting catchy lingo to everybody they meet.
I suppose it's not exactly the funniest thing to someone who hasn't truly experienced a role play server. All you need to know is this. There are two people on role play servers. The kind that are serious, and the kind get together and pretend they're Popeye, Olive Oyl, and Blutto.
