Ghirahim (Zelda: Skyward Sword)
Ghirahim is amazing, blah blah blah, fuck Skull Kid, blah blah blah. If you don't know that I'm a huge Ghirahim fanboy, you're either living under a rock or you don't know me well. Ghirahim and Skull Kid are among the most wanted Zelda characters in SSB4, and unlike Skull Kid, Ghirahim is actually relevant
. Skull Kid's game (Majora's Mask) was a ages ago, and while I do quite like it, Skyward Sword is really new and thus is more likely to get a representative. Plus, Skull Kid has no fighting style, and he's not even a notable villain. Ghirahim is fabulous, is active and important in the story, and has a clearly established fighting style. Also, I think that Ghiry has a bigger fanbase then Skull Kid, despite what certain polls may tell you.
Fan moveset: B Move
: Dagger Shot
Ghirahim starts levitating a dagger in front of him. Tapping B will cause him to throw just one (the dagger moves horizontally and is not affected by gravity). But holding down B causes him to gather more daggers, stacking them on top of each other. There can be up to six daggers, and the more there are, the greater vertical area they can hit. One dagger does not do very much damage, but if a lot of them hit something it will really hurt them. Ghirahim can levitate the daggers as long as he wants; this can be useful because they can protect him from projectiles. They do vanish on contact, though. Side B
: Barrier Slasher
Ghirahim moves forward very quickly at fast speed. It's very similar to Ike's side B, only, when this attack hits, Ghirahim will attempt to slash his target many times very quickly. It also breaks any shield on the first hit, hence the name. It also has no charge time, unlike Ike's. But it can cause Ghirahim to go flying off the edge of a stage. Thankfully, pressing B will stop it immediately. Down B
: Diamond Tornado
Ghirahim raises his palm into the air. After a brief moment, a black tornado about his height will erupt from it. It is black with diamond sparkles. Anyone above Ghirahim that is caught in this attack will be stuck in falling mode (the mode most characters go into after using their Up B, aka helpless). Taking your finger off B will quickly cause Ghirahim to cease using the attack so he can attack the helpless victim. Up B
: Demon Jump
Ghirahim leaps into the air. The height is about the same as King Dedede's Up B. Tapping B at any time during this will cause him to teleport in a burst of diamonds. Moving the control stick will decide where he reappears; he reappears after about 2 seconds. Immediately after reappearing he dives downward with his sword pointing where he is moving. He slashes through any characters in his way. Since you have little horizontal control during this decent, you can cancel the attack with B, putting Ghirahim is helpless mode but allowing him to maneuver better.
Just a note: not using the teleport will result in him not being put in helpless mode. The teleport distance is also about the same as Meta Knights. Warning: Skyward Sword Spoilers! Final Smash
