White Light

White Light is the combined light of all the Prism Monsters and the final boss of Attack the Light.

Powers
Being the combined energy of all the previous bosses fought, he has all their powers and the powers of the unfought Lights.

Purple Laser: A laser beam that attacks one gem. It cannot be blocked by quick time actions but can be blocked by Steven's Bubble. White Light will use this move if the player picks the wrong dialogue choice.

Blue Shockball: A small blue energy ball that attacks one gem. If not blocked, the gem will be paralyzed and lose an action of the next turn.

Red Fireball: A powerful burst of fire that attacks one gem. If not blocked, the gem will be burned.

Orange Burst: Multiple energy blasts that attacks all of the gems.

Light Change: White Light will change his colors. The color he changes into determines which attack he'll use next.

Boss Fight
White Light has all the powers of the previously fought bosses and more. Once his health gets low enough, he will stop taking damage and begin communicating with Steven. At this point, the player must choose the right dialouge box or White Light will interrupt with Purple Laser.
