I ususally link to Paperback Writer's consistently excellent posts on Web Writer, my blog collection of advice and tips for authors. I've done so on this occasion, too. But I just have to share with you PBW's collection of "protag no-nos", or as one might translate, "cliched main characters".
Abracadabra Erection Dude; Freckle Sprinkle Girl; Inexplicably Stumped PI; Love Scene Interruptus; Needle Teeth; Oncoming Betrayal Headlights; Supermodel Family Girls; Too Sexy for his Shirt; Unconvincing Flaws; and Wolverine Wounds.
I can't pretend to recognise all of these, but I certainly do some and for the others I get the picture even if I've been spared the experience. The chuckle-inducing definitions are at the link.
