B = Earth Divide: (Seen at 3:43, first video)
Nightmare raises Soul Edge as it is lit on fire, and then he slams the blade down causing a small shockwave. Earth Divide works in a similar manner to Marth and Roy’s Shield Breakers in Melee, unleashing a powerful arching slash. Earth Divide can deal somewhere between 10%-30% damage depending on how long the B button is held. The shock wave that Earth Divide leaves will push enemies back greatly, making for a good knockout move if you get lucky. Like the Drop Kick, if the Earth Divide misses, Nightmare can easily be punished for it.
Earth Divide, much like in the Soul Calibur games, is a risky move. It’s slow, predictable, yet pretty powerful. Instead of doing tons of damage like in the Soul Calibur games, Earth Divide has great knockback. This is the type of move that shouldn’t be relied on in a one on one fight; rather Earth Divide can find better use in free for all battles or tag matches.
Forward + B = Rush Crusher: (Seen at 5:47, first video)
Nightmare will dash forward at a surprising speed and strikes with his claw. This move can work as quick knockout attack at an un-expecting enemy. Rush Crusher has less range than the Fox Illusion, but can push the opponent quite far. Pressing the B button again makes Nightmare follow up with tackle. The first hit Deals 13% damage. The second deals 6% damage.
The reason one wouldn’t want to just continually spam the B button while performing the Rush Crusher is that the single hit can be combo-ed into by moves like Soul Wave, Slash Cross, and/or Dark High Kick on the ground. While in the air version of the attack can be combo-ed into and out of both the Rising Knight Kick and Fatal Brave Kick. The second hit would push the enemy too far to get a good combo.
Up + B = Soul Blaze/Cannonball Splitter: (Seen at 4:50 and 5:06, both on the second video)
Nightmare starts off by using a burning upward slash that will, unlike in Soul Calibur 3; raise him off of the ground. This initial attack deals 12% damage. Soul Blaze acts as a recovery attack for Nightmare and has the same height as Mario’s Super Jump Punch.
If the B button is hit again during the animation for Soul Blaze, Nightmare will then perform the Cannonball Splitter.
The Cannonball Splitter has Nightmare do a downwards spinning slash that moves diagonally. The Cannonball Splitter deals 8% damage. If you aren’t careful you could ring yourself out.
Down + B = Soul Wave: (Seen at 4:36, second video)
A newer move that Nightmare has access to starting in Soul Calibur 3, it has so far stayed with him since. Nightmare charges energy from his entire body, then releases it in an explosive red force field. Soul Wave’s design should look more like the version that was in SC4 and SC5, with a more noticeable hitbox and flashier look. This move has slightly more range as the Reflector, to fit Nightmare’s size better.
Soul Wave can be charged the longer the button is held, instead of dealing more damage, Soul Wave’s range can be doubled. This move has decent knockback, so it’s good for pushing enemies off of your back quickly. Normally Soul Wave deals an even 10% damage. Soul Wave has a sweet spot around Nightmare’s legs, which in turn makes Soul Wave deal 15% damage instead.
Soul Wave is a good surprise attack to use at the end of combos. And in the air, it’s the only option that Nightmare has that is abuse able.
