Hmm.. Its been since 2009 since the bulk of the recomendations.. Lets fix that shall we?
WARNING: My reviews suck, so just trust me, they're really good xD
Quantum Vibe is a good webcomic set in the future in our solar system.
Mokepon is a pokemon webcomic set in what appears to be the future of the anime. It tells the tale of a trainer that doesn't really want to be a trainer. Atticus is pretty enjoyable to read, and Dragonthing is pretty awesome.
Henchmen for Hire is not a webcomic about heroes or supervillians. Its about the henchmen of said supervillians and how they opperate. Pretty enjoyable.
Grrl Power is so far short as it only updates weekly. Its a take on modern civilization only super powered being are starting to come around. And teh government is putting a team together. So far it's been pretty enjoyable. Sydney is pretty hilarious and the the plot seems to be moving in very interesting directions.
Far Out There Trigger was raised in secret to be the ultimate saboteur. He is all set to take down the world's government.. Only to find out he wasn't actually needed and the mission he was raised for happened years ago. Well, the only thing he can do is head off with his friend Layla and explore the world.
Modest Medusa What would you do if a child Medusa came out of a magical portal in your toilet? Make it a member of your family of course. Its recently gotten away from teh lightheartedness of the early comics and gotten into a pretty decent story and plot now.
Unshelved is a webcomic about Librarians. If you enjoy books and like a good laugh, this webcomic is for you.
