Here a few of my favorite online comics. Hopefully others will add to this selection:

The Blackblood Alliance

The story of the wolves of Inaria and the banished Royal Guard. When the lands of Inaria are invaded by fierce Sabre-toothed cats the pack call for their greatest fighters, the banished Blackbloods. But after all that Inaria has done to their kin will the Blackbloods, lead by their Alpha Swiftkill and her sister Bloodspill, heed the call of those who sent them away?

Vol.1 is for sale now (but you can read without buying).Breath taking artwork, engaging characters with a well thought out plot that makes you want more by the end! I've been following this comic for a long time and recomend it to anyone, it doesn't matter if you like wolves or not.

The reason you read this comic is not for 'ooh prettah wolvies!' but because you really want to find out about the characters. And with a wonderful lead like Swiftkill who could blame you?

The Zombie Hunters

Jenny the shovel wielding zombie-slayer leads her team of sarcastic medic Sammy, navigations officer Katie, Half-zombie and gentleman Charlie, sharpshooter 'man with the plan' Dan and get away driver Maureen into a zombie infested 'Red Zone' in order to do a little bit of looting, but it all goes horribly wrong!

There's everything you could ever want: Gore, angst, puns and 'Your Momma' jokes. It's 28 days later but with more actual dead people and plot!

Great for horror fans or people who just like to watch someone make a fool of themselves. The story so far has a light-hearted feel while keeping up the gore and suspence a real zombie fan enjoys.

Snafu Comics

A bunch of different web-comics, all a high standard. From the joking Snafu strips: parodying everything from The Hoff to Taste of Chaos, to the Dojinshi style Grim Tales from Down Below (For anyone who has seen the Grim tales of Billy and Mandy, but can also be read alone.) and the beautifully written Ever After with it's psycotic Little Red Riding Hood and traumatised Goldilocks- Everything on this site is gold.

Toy Story X

Because I make it.

Roza and the Horse Prince
I'm not quite sure where the story is going yet, but the art is beautiful, and it has a goat in it . . . :P

Order of the Stick
I'd imagine most web comic readers will have heard of this one by now, but if you haven't, get to it! It's a very clever, very funny comic set in a fantasy RPG-type gaming universe. Um. Just read it.

Lackadaisy Cats
An incredibly well drawn comic (check out the facial expressions!) set in St. Louis during the Prohibition. Very clever, and very funny. Can also be found on the artist's dA page.
