Eliminate Sylux's shield by destroying his nanomachine arms. Shoot the glowing tips of each arm then use Psychic Lasso to pull them off. After all arms are eliminated, take the opportunity to shoot Sylux before he regenerates the arms.
Psychic Lasso Effects and How to Unlock
While Sylux's nanomachine arms are active, dodge out of the way while focusing on shooting the arms. Many of the arms' attacks consist of slamming the floor and swiping across it, prompting you to jump over them.
After disarming all nanomachine arms for the first time, Sylux will generate dragon heads in their place. The dragon aheads attack fast, so make sure to keep your distance and dodge out of the way. The heads will eventually morph back to nanomachine arms.

When Sylux enters Lockjaw mode, he can hit you and steal your Energy Tank. If hit, you have to mash the A button to get out of being stunned. To stop Stylux, toggle Morph Ball and perform Boost Ball to stun him and retrieve your stolen Energy Tanks.
Toggle Morph Ball by pressing Y, then perform Boost Ball by pressing B or L.
When Sylux summons a miniature black hole, fire a Control Beam to hit Sylux, interrupting him from the attack.
Control Beam How to Unlock and Effects
One of Sylux's most damaging attacks is a charged beam that drains your HP. Before Sylux fires the beam, quickly dash out of the way before it makes contact with you. You can tell if Sylux is preparing for this attack by the crackling electricity around him.
| Front Wave |

| Sylux charges forward with an electric wave. Double jump or dash away from the wave to evade it. |
| Shockwave Slam |
| Sylux slams the ground, creating a shockwave that gradually increases its height. Double jump over the wave before it becomes too high. Sylux can also perform a follow-up attack with a lower wave. |
| Shockwave Blast |
| After being stunned for a moment, Sylux will emit a wide-reaching blast that knocks you back. Toggle Morph Ball to duck under the blast's radius. |
| Electric Surge |
| Sylux sends a vertical electric surge toward you. Dash away to avoid it. In the last third of his HP bar, Sylux will begin to summon multiple surges you have to dodge away from. |
| Horizontal Beam |
| Sylux fires a horizontal beam in a semi-circular motion. Double jump or enter Morph Ball mode to dodge it. Sylux will also perform a low variation you have to jump over. |
