Kankri. Because he pissed everyone off and wordswordswords was his gimmick. Not necessarily due to the far left political views that he parodied. Overall, total waste of time.
I had this genius plan after spending 3 months reading the fucking thing to signal that I was a "fan". I printed out this picture of Kankri and taped it to one of my folders. The girl noticed it one day and asked if I liked homestuck. My spaghetti launched itself mach speed out of my pockets and I immediately replied with "no". She just stared at me for a bit and said "ok". We never talked after that. Fuck my gay retarded life.
