Paul Peterson is a character in Mr. Peabody and Sherman, who gets mad at Mr. Peabody about the incident with Sherman and Penny but later becomes good with Mr Peabody, as he shows Paul his intelligence.
He is a very serious stern who is easily angered and distracted by his phone calls. He doesn't seem to like Peabody very much and not very interested. At first, he does not like Peabody but after fixing his back, he grows fond of Peabody. He also seems to care a lot for Penny.
- Some say that Paul was going to be the main antagonist but with the release in the United Kingdom it is revealed that Paul Peterson is not the main antagonist and that Mrs. Grunion is.
- Steven Colbert (the voice actor for Paul) also voiced the President in another Dreamworks movie, Monsters vs. Aliens.
