I keep finding them and adding them to my delicious account, thought I should chuck them up here. Many of these are from fancomiccentral.

• Mokepon The amusing story of a cynical teenager trying very hard not to make friends or learn important life lessons in the world of Pokemon.
  
• Encyclopedia of Weirdness: A Weekly Supernatural Fan Comic These are great little one off comics.
  
• cap_ironman A bunch of Captain America/Iron Man fancomics. Not really my thing but it's nice to see a fandom embrace the medium.
  
• Batman and sons (also the_dark_cat) Cute fanart and fancomics about batman and his many adorable young sons (don't ask me how it relates to canon!)
  
• Showdown: HP vs. Twilight Amusing one-shot, made before Twilight bashing got quite so old.
