People are forgetting the iron knuckle. -_-
I also think that too many people are deciding based on how hard it was for THEM.
personally, I think dead hand would be eliminated first. All he does is move towards you and bite you. I don't think that would do much against the big lump of flesh that is big octo. He would burn his mouth or something on flare dancer. Good luck penetrating iron nuckle's armor. You can't really bite invisable ghosts (poe sisters), and dark link could just slash him with a sword while he inches toward him.
Poe sisters would get eliminated soon after...
Big octo would probably get slashed open in a few hits by dark link, it's not very likely that the battle will take place in the exact same stage. Flare dancer would be able to get behind him easily with his speed. Iron nuckle; again, good luck running over someone who is basically a walking statue.
Now, iron nuckle would probably be eliminated next, he only requires a sword and some speed to beat him, which dark link seems to have. Flare dancer, the heat could go right through the armor.
And this is where dark link's reign of terror ends. Flare dancer- a walking din's fire. Which happens to be dark link's main weakness.
