Tentacle Pierce: Same as before, but even faster.
Deceptive Lunge: An improved version of Tangled Rush, but 6 portals with each tentacle swiping a full circle with 3 at top & 3 at bottom & then lunge.
Crushing Shade: Conjures a hammer & swings a few times.
Thorn Spray: Same as before, but the blasts are also coming out his fingers & toes & he throws the last shot like a Spirit Bomb.
Hammer Spin: Spins around with the hammer several times.
Shadow Volcano: Provokes a volcanic eruption of darkness out of the abyss & the eruption hits the middle, left or right of the screen & covers 1/3 of it.
Ruthless Riot: Charges & catches Master Soul or Galeem, strangles them, slams them into the ground, drilling into them & then slamming them into the screen.
Chains of Darkness: Sends out several chains to hold Master Soul or Galeem in place, which is what he used to hold Galeem hostage if the fighters decided to weaken Galeem 1st.
Absolute Chaos: Charges & sends an explosion of unbearably evil, suffering & violent darkness that makes the screen go black with only Master Soul & Galeem visible for a moment.
