Welcome to The Cave of Dragonflies forums, where the smallest bugs live alongside the strongest dragons.
Guests are not able to post messages or even read certain areas of the forums. Now, that's boring, don't you think? Registration, on the other hand, is simple, completely free of charge, and does not require you to give out any personal information at all. As soon as you register, you can take part in some of the happy fun things at the forums such as posting messages, voting in polls, sending private messages to people and being told that this is where we drink tea and eat cod.
Of course I'm not forcing you to do anything if you don't want to, but seriously, what have you got to lose? Five seconds of your life?
Not the final boss but on hard/intense duon is a bastard on boss battles and almost always knocks me out.
Well, aside from what Exo-Raikou said, characters with projectiles also make the battle a whole lot easier. Otherwise, you can get behind (or, alternately, on top of) Duon and, when he fires those missiles (from the pink side) they'll ram into him and do major damage, and not only that, he'll make no attempt to dodge them. Though if you're on top of Duon rather than behind, they're likely to hit you as well. However, when you're on top he'll take more damage from your Down Smash (due to being hit from all sides), and he can't (?) shake you off with his spinning attack, so try to be behind him when the missiles strike and on top when you attack.Not the final boss but on hard/intense duon is a bastard on boss battles and almost always knocks me out.
Thought of another one: Mecha Sonic from Sonic 3 and Knuckles, in Knuckles' story. When he goes super, not only do you have to worry about him shooting/dive-bombing you, but you have a very limited attack opportunity when he tries to go back to the Master Emerald. Sure, if you have good timing and you're fast, you can take him out quickly, but if you're like me and lack those... he's a fricking pain!
But almost all of the final bosses in the early Sonic games were like that - very quick attacks and little opportunity to get hits in. However, remember that there is one thing that makes this one fight easier than all of the other final bosses of that era: YOU ACTUALLY HAVE RINGS.
Kurt Ziza from KH1. man, that battle is frustrating...
