Overview: Ghirahim isn't particularly fast, preferring to calmly strut around the arena. However he is capable of quick bursts of speed and agility. Ghirahim is empty-handed by default but can summon weapons with a snap of his fingers. Mid-weight, falls relatively fast.
Specials
Neutral Special: Summon Daggers. Holding B begins to summon crimson daggers that circle around Ghirahim. Up to 5 can be summoned. Releasing B fires the daggers simultaneously. You cannot store the charge, but you can move around while charging (similar to DeDeDe's down special in Brawl). Individual daggers do little damage or knockback, on par with Sheik's needles. Hitting with all 5 is much more powerful. Range is about 3/4 of Battlefield.
Custom 1: Summon up to 8 daggers with a faster charge time, which will fire in all directions. Not a reliable damage dealer, but good for area control.
Custom 2: Summon up to 3 daggers with a slower charge time. Daggers travel slower but will home in on opponents.
Side Special: Skyward Strike. Probably shouldn't be called that but is functionally similar to Link's Skyward Strike from SS. Ghirahim points his sword up, charging it with energy, then swings vertically launching a spinning crescent of energy. Range is less than half of battlefield. Relatively low damage and knockback but higher on both counts than the individual daggers.
Custom 1: Launch a larger, slower projectile with less range. Hits multiple times, pushing opponent away.
Custom 2: Bypass the startup animation, instantly firing a faster but weaker projectile.
Up Special: Teleport Strike. Ghirahim snaps his fingers and teleports. The direction of the teleport is controllable and has range on par with Sheik's teleport. No hitbox at the beginning of the teleport, but upon reappearing he strikes with a sword. If in midair, he then goes into helpless state. The strike can be a kill move at higher percentages but is difficult to land.
Custom 1: Decreases the range of the teleport, but Ghirahim attacks with his two-handed sword for more damage and knockback.
Custom 2: Increases the range of the teleport, but removes the strike at the end.
Down Special: Parry. Ghirahim briefly extends his hand. If an opponent attacks him from the front, he will catch the attack and thrust them backward, taking no damage. Does no damage, and has set horizontal knockback which allows him to follow up with other attacks. Does not defend against projectiles or attacks from behind.
Custom 1: Ghirahim charges his outstretched hand with electricity. Attackers take damage but suffer little knockback, and it is harder for Ghirahim to follow up. Damage dealt is not dependent on the strength of the opponent's attack.
Custom 2: When Ghirahim catches an attack, he deals neither damage nor knockback but instead slips around to the opponent's rear, facing them. Good for punishing attacks with high ending lag.
Standard Attacks
Jab Combo: Repeatedly pressing A gives a flurry of punches from one hand. For the finishing blow, Ghirahim summons a sword into his other hand and strikes upward.

Dash Attack: Ghirahim strikes horizontally with a sword after a burst of speed. Similar to his charging attack from the first battle against him in SS.
Neutral Aerial: Swing two swords in a horizontal circle. Can hit twice on either side, the second hit being more powerful.
Forward Aerial: A forward roll while swinging two swords in parallel. Begins with a meteor hit in front of him, then a weak hit on all sides as the swords come around.
Back Aerial: Ghirahim extends an electrified fist backward. Can be a potent kill move if sweetspotted.
