I'll tell you who mine is. Yuffie from Final Fantasy 7. I will never forget the day she stole all my materia and left me high and dry. On top of that, I had not obtained many potions throughout my travels and the cheeky wench told the guys in Wutai to not sell me anything >.< So I could not even heal my self at all.
Then when I finally did find her she legged it and had me chasing her round Wutai trying to find her... grrr
The amount of times I ran past the barrel and didn't see it move would seem exaggerated, but it took me 4 days to find her when she hid in there lol.
So then I get going into the mountains after countless hours and realize I can't defeat the enemies because I can't heal myself and had to get back in the tiny bronco and sail all the way back across the ocean just to get some potions.
So who was your most memorable character? Or characters if you have more than one.
