Believe it or not, this comic actually got fanart back in the day! I've compiled them below. I don't expect anyone today to send me any new fanart, but if you somehow decide to do so, ping me on twitter (@linaciari) and I'll make sure to put it on this page.
Additionally, while I've done my best to update the names of the artists, I couldn't find information on all of them. Let me know if you have any updates for me.
By Beefy - this one makes Gadget into a character from Firefly
By CatKanako - I think the Medicines would get along!
By Dobbers - and yeah, Merchant is now Auron from Final Fantasy X
By Ed Ramos
By Jade Armstrong
By Kanako - love the Gorillaz reference!
