Mixed Myth

Mixed Myth is a complete online fantasy comic created by Robin Meyer. It finished with a grand finale in 2005 and the front page is secured for spoilers.

The story follows Keeva, a Goblin-Elf with a weakness for explosives, and her 'noble' demon-steed Puch, on their quest to find out why the world suddenly seems to want to kill Keeva. On her way Keeva stumbles upon some rather incompetent asssasins; Tamit, a Sphinx with mislaid memories. And Aidan, a half-selkie werewolf. The assasins both do a quick Heel Face Turn and join her.

Tropes used in Mixed Myth include:

Anti-Hero: All of them
Can't Hold His Liquor: Don't let Puch near alcohol. Which also turns the horse into a Drunk Driver
Fantastic Racism: Elves, nuf said.
Fortune Teller: Though he mainly look backwards and he can only devine one, one single day.
Genre Blind: Elves base their magic on a force called "Cynamatik" which, while powerful, has a mind of its own and tends to turn on them at exactly the wrong moment. Mostly because they don't seem to realize they're the villains in this story.
Living MacGuffin: Keeva, apparently.
Mysterious Past: Everyone. And the origin of the Elves.
Our Elves Are Better: And decended from bunnies.
Riddle of the Sphinx: Tamit tries this on Keeva, but she can't remember the answer, so they have to go back to Tamit's place to check. Keeva's wrong, by the standards of "gave the answer Tamit had written down", but since it was technically correct in meeting the terms of the riddle and Tamit's started to like her, she gets points for originality.
Theory of Narrative Causality: Cynamatik, the power elves use to fuel their magic. It essentially guarantees their success for as long as it's dramatically appropriate--but it also guarantees their downfall when that's dramatically important.
