THE COMIC ZONE
In my effort to find more indie webcomics, I have compiled a list which you may peruse. They are mostly sorted by vibe, genre, or subject matter, and then alphabetically. Most here are webcomics, but I'll also point out small indie publications, presses, collectives, and events (focused on the UK, where I'm from). If you have any of your own recommendations, please put them in the comment box so that I can add them!
This list is and always be a work in progress; I haven't read every comic under the sun... yet.

Superpowers
Inhibit by Eve Greenwood (WC)(P): Victor is a resident at a home for kids who haven't proven they can control their powers. With his window to prove himself closing, Victor's life grows more complicated until he is wrapped up in the plots of friends and enemies.
Recoil by Spire Eaton (WC)(P): Our protagonist, Kalo, discovers he has powers in a deadly accident and is taken to an institution that may not be what it seems...
Robot(ic)s
Mega Robo Bros by Niell Cameron (P): Alex and Freddy are normal brothers in a futuristic London, except for the fact that they are superpowered robots! Also available from Niell's shop.
Serious Engineering by Roman Jones (WC): Corelle is 16, brilliant with machines, and working in a chicken processing plant. When an illness spreads through the workers and puts her hands in danger, Corelle is spurred to travel to Polaris Robotics in search of a better lot in life.
Space
Cato's Apprenticeship by Joey Ballast (WC): Cato is struggling with his new implant, his drill exercises, and fitting in with his friends. Life on a spaceship is harder than you might think, especially when a heavily armoured figure clomps its way onto the ship...
