One of the reasons I love comics is because any insane, whacked out idea goes. Take this character, for instance:
This is Frobisher. He is a shapeshifting alien private detective who (and this is the best bit) just feels most comfortable in the shape of a penguin. Even better, he isn't even the big idea of the comic he's in, he was a companion in the Doctor Who Magazine comic strip.
I bloody love comics.
