How does Dr Manhattan disintegrate people ?

How does Dr Manhattan disintegrate people and what power is it called ?

Open his hand. Every other matter manipulator needs to raise their hands and concentrate.

Matter/Molecule manipulation. He opens his hand and there atoms disintegrate.

Like a boss.

@inoscopedjfk1234: He tears them apart, atom by atom.

IIRC, he removes their 'intrinsic field'. That (gravitational?) force that holds an objects molecules together is removed, resulting in the targets molecules dissipating violently in all directions. Essentially, he does the same thing to others as was done to him in the accident that destroyed his human form.

he lifts his hand

He raises his arm and they're gone.

and this

It's like asking "how do you move your arm". You just do it!

His body is built to bring out and use the great potential power within atoms and use that power to destroy others.

Every gram of matter or fraction of it is a potential atomic/nuclear bomb. Dr. Manhattan is able to tap into this power.

He's omnipotent
