What do you call a manipulative person? [closed]

What is the most appropriate (single word) noun to describe someone who is manipulative? That is, in the sense of manipulating people in a negative context.

Edit:

In the original discussion from which this question arose, we rejected manipulator on the grounds that it felt too much to apply to someone manipulating objects rather than people. (That is of course, just opinion.)

Manipulator remains the best noun to describe a manipulative person with either connotation:

  1. A person who controls or influences others in a clever or unscrupulous way.

  2. A person who handles or controls something skillfully.

Solution 2:

If the manipulations are selfishly motivated with the goal of getting ahead, then Machiavellian fits.

More generally, artful. If the manipulations are subtle, then sly.

Solution 3:

The best single word to describe someone who is manipulative, is "manipulative".

"a manipulative person tries to control people to their advantage" CDO

Other adjectives such as "designing", "artful", "shrewd", etc, won't describe manipulative any better.

I just google.commed this.

Solution 5:

Somebody who manipulates other people, in particular if they (or the public at large) are not aware of it, is a puppetmaster.
