Who is the plaintiff in a criminal court case? the defendant the government the judge the juror

In the criminal court case, the Plaintiff is the Government.
A plaintiff is someone who brings the case against a certain group or individual in a court of law.
For criminal cases, this will be brought by a public official called the federal Prosecutor that acted on the behalf of United States' attorney.

I say none of them because the plaintiff is the one is suing the defendant is defending themselves from the plaintiff the government is the person that hires judges the judge is the one hearing the case and the jury is the people in the back watching and making the decision  with the judge but only if the judge agrees, it is final who wins.
