Dancing Hawk is an NPC in my Wandering Heroes of Ogre Gate campaign who developed a grudge with the party after they killed Madame Hamaya and had several confrontations with them. He fought them on three occasions, and each time he managed to roll 1s on his attack rolls and never actually struck any of the player characters. By their third encounter the party had tired of his quest for vengeance so they killed him.
Looking at his stat block above, you can see he isn't a stellar martial hero but he isn't terrible either (and in the campaign his Qi rank actually went up to 3 or 4 by the last battle). Still he always had an air of Don Knotts about him.
This past session, he came back in the form of a phantom and fought the PCs one last time. He attacked the party once each round, and rolled 1s both times, then the characters destroyed him in a hail of daggers.
This is a character fated to failure. In over twenty years of GMing, I have never seen an NPC fail so badly and with such consistency.
