In the world of comics, there's generally very few 'normal' characters. Superheroes fight crime in skin-tight lycra, horror monsters lurk in the darkest corners of your imagination, and even those who appear like regular people are largely set up to appear ordinary so that when their dark secret is revealed, it's all the more surprising.
But the usual standard of eccentric characters is easily totally outstaged by some individuals. Through weird backstories, weird appearances, or weird personalities - or sometimes all three - some figures just naturally stand out far more than others. And this is a blessing in disguise, as while it can be totally jarring to have a naked spider assassin rock up into your comic, it's also undeniably fascinating to witness what the wilderness that is the human mind can create when it's pushed to get as wild as possible.
Though you may spend as much time wondering how a real human came up with these characters as you do actually reading about them, you can at least safely say that they're never boring.
