Master Core / Master Fortress beaten on 9.0 difficulty in Super Smash Bros for Wii U. 9.0 Master Core can be fought when going though Classic Mode on the highest difficulty, without getting a game over. The battle is separated in 6 segments: Master Hand & Crazy Hand: You start off fighting against the hands, but unlike a normal battle against the hands you now only have to deal an "x" amount of damage to defeat them. Despite the sort fight, this can be real annoying at some times, but luckily I made it out fine with no damage. :) Master Giant: The first form of Master Core which appears on difficulties 7.0 or higher I believe. There weren't too many mistakes here, with the exception of the Core's first attack, with I didn't block properly. I'm fine with it though. Master Beast: Master Core's 2nd form (on high difficulties that is). This one can be quite unexpected due to its fast movements. (Mainly on 9.0 difficulty) -- I missed some attacks, and took some hits but I beat it relatively fast. Master Swords: Master Core's 3th form, which is sometimes seen as MC's hardest phase by people. It has quick movements, but your shield should do really well here. (If you time it correct of course) -- I had a good beggining but messed up at the end and also got a dead here. It got pretty tense at the end. Master Shadow: Master Core's 4th form. It's basically a copy of your fighter, except larger. It shrinks upon taking damage though. It can be defeated by either knocking it out or dealing an "x" amount of damage. This phase usually shouldn't give you too much trouble, but your 'duplicate' can be real annoying though, mainly when high damage. Thankfully nothing bad happened here. I took a few hits, but luckily they weren't charged attacks or some other kind of strong hits. Phew! Master Fortress: Master Core's final form, which is only available to fight at difficulties 8.0 or higher. Master Fortess has four phases: Phase 1: Relatively simple. Just make your way to the right and you'll find a weak spot. Plasma Wisps can easily be defeatedd be grabbing (and throwing). I did pretty well here with barely any damage taken. :) Phase 2: A little more difficult, but I did a nice job here, with once again barely any damage taken. Keep an eye out for Danger Zones (that yellow-like stuff you'll encounter around the walls and on the ground) since hitting them will deal quite a bit of damage, and above 100% you'll be instantly KO'd. Phase 3: Pretty much like Phase 1, though I tend to have a lot more problems here for some reason. Once you make it to the open section it gets a lot easier in my opinion. Phase 4: Final phase and definitely the hardest with lots of Danger Zones and enemies. It's mostly about remembering and taking down enemies here. Things got really tense near the end. Master Core's true form: Upon defeating Master Core (no matter what difficulty you're playing at) he'll finally reveal his true form. Take this Smash Ball thing down ASAP, because when waiting too long he's got a nasty surprise for you...(https://youtu.be/bs5GK4SI2i4) Sunny Crappy on Twitter: twitter.com/sunnycrappys
