Without going into all the details . . .
Neutral
Phazon Punch (A, A)
This behaves like a
one-two punch, which is different from Samus' left punch to swinging arm cannon.
Dash
Speed Boost (Dash+A)
Dark Samus' dash attack has the same animation as that of Samus' dash. When Dark Samus performs this attack,
her body will glow in a manner that indicates she has heavy armor for that duration. This attack is a combo set-up.
Tilts
Aú sem Mão (Up+A)
Dark Samus will do a flip, bringing her left or right leg to an arc depending on the direction she's facing, following up with her other leg to bring a full swing against her opponent. With the recent
victory screen of Dark Samus in her trailer, people might recognize this animation.
Side Kick (Forward+A)
Dark Samus' side tilt is a kick like Samus', except Dark Samus delivers a kick sideways relative to her. In doing so, she leans toward her opponent before returning to her original position. This allows for her to maintain a safe distance from her opponent.
Phazon Tentacles (Down+A)
Phazon Tentacles is an ability Dark Samus had in Metroid Prime 2: Echoes, but it appeared as a clear, cylindrical barrier with Phazon energy in MP2:E . In Metroid Prime 3: Corruption (MP3:C), this attack ended up appearing as seen in the .gif. This attack allows Dark Samus to push enemies away if they get too close. It covers a lot of range on both sides, so this is also effective against those who roll a lot.
Smashes
Phazon Spheres (Up+A)
This attack may seem familiar to those who have seen the Dark Samus assist trophy where she releases giant, blue spheres, and that's probably because the attack seen from the assist trophy is based on this particular attack in MP3:C. The animation would appear as it does in MP3:C and be smaller in size. It would retain its homing effect.
Plasma Beam (Forward+A)
Similar to Mega Man's Charge Shot, but with a bit more range, Plasma Beam is a strong smash attack capable of killing. It can be angled diagonally up or down.
Boost Ball (Down+A)
Similar to Sonic's down smash in Super Smash Bros. Brawl and nothing like Jigglypuff's Rollout or Yoshi's Egg Roll, Dark Samus transforms into her morph ball form and dashes back and forth between a short distance. This attack can kill.
Aerials
Radioactive Burst (A)
Dark Samus generates a burst of energy, knocking away any opponent nearby. The hitbox surrounds Dark Samus and is a useful tool for breaking free from combos. It's capable of killing, just like Samus' n-air.
Drill Kick (Up+A)
This attack is the same as Samus' u-air.
Helicopter Kick (Forward+A)
This is a multi-hit attack, which covers a lot of range in the air.
Back Kick (Back+A)
This is pretty much the same as Samus' b-air.
Phazon Burst (Down+A)
Somewhat similar to Samus' d-air, except when Dark Samus uses this attack, she'll fire a burst of Phazon energy, which will propel her upward while spiking her opponent with a meteor smash.
Specials
Neutral
Scatter Shot (B)
Dark Samus fires Phazon bullets, with each bullet producing 1% damage. Uncharged Scatter Shot deals 3% damage, and a fully charged Scatter Shot deals 21% damage. This is consistent with the Dark Samus assist trophy.
Kinetic Phazon Cannon (Up+B)
Dark Samus never showed the ability to use Screw Attack. This is the next best option for her recovery. During this time, Dark Samus would have super armor. If she hits the side of the stage, she would be able to wall-bounce, just like Ness or Lucas. This attack would have the option of being fired in any direction, just like Sheik's Vanish. And if Dark Samus were to use it and hit the ground,
she'd create a shock wave.
Super/Phazon Missile (Forward+B)
Dark Samus will shoot a super missile, and when treated as a smash, she'll fire a Phazon missiles. Phazon missiles would freeze the opponent in place.
? (Down+B)
I'm still not certain what I'd make this. Bombs would be nice as a recovery option, but Dark Samus never uses bombs. I thought about having this work as a dark echo, but I'm still not sure about that, either.
Grab
Grab (Z or L/R+A)
Dark Samus wouldn't have a tether grab.
