Sherman

Sherman J. Peabody is the deuteragonist of Peabody's Improbable History. He is a lovable and brave young boy and is owned by Mr. Peabody.

Physical Appearance
Sherman is an adorable short little boy with red hair and black eyes (amber in the film). He wears round glasses like Mr. Peabody. Usually, he wears a white t-shirt, and black shorts, but in early cartoons, he wore a red belt and matching glasses. (In the film) during WABAC trips, he changes into the outfits Peabody instructs him to wear to blend in with the people in the time period.

Personality
Sherman is a very bright boy. He is very curious, rambunctious, fun loving, mischievous, and overall enthusiastic. He watches out for Peabody and wants to impress Penny. At first, he and Penny hated each other, but then they developed a strong friendship. Peabody adopted Sherman when he was a young boy. He has a huge crush on Penny. The reason Sherman showed Penny the WABAC was because he wanted to impress her and make her like him. He appears to be somewhat of a pushover, as he allowed Penny to goad him into showing her the WABAC and to use it to travel through time. It was also shown that he obeyed Mr. Peabody to the letter, as whenever Penny asked Sherman to do something, he would always say, "but Mr. Peabody says...". However, he is good natured and loyal to those he loves, such as Penny and Mr. Peabody, as shown when he risked destroying the fabric of time to go back to when Mr. Peabody was alive (Sherman assumed Mr. Peabody had died saving him when in reality he had lived) despite Mr. Peabody's warning that traveling to a time where you exist is dangerous in order to save him.

1960s Sherman
Sherman is Peabody's sidekick and pet and therefore very obedient to Peabody. He is very curious and mischievous but always behaves very well due to Peabody's strict nature. He is rather simpleminded, often catching on slow to Peabody's plans during their time travel adventures. Sometimes, he can jump to conclusions and that leads to trouble. Regardless, Sherman is the best friend Mr. Peabody could ask for.

Movie Sherman
Sherman is a very bright, mischevious, fun-loving, smart and ambitious boy who knows much about history due to his trips in the WABAC with his father and in fact takes after him in many aspects. He also has a crush on Penny Peterson, his best friend and despises it when other boys flirt with her and is somewhat stubborn.

2015 Series Sherman
Sherman is extremely fun-loving and kind, but absolutely loves to have fun. He is a little more reckless than his previous incarnations, not as bright, kind of loud, a bit obnoxious and seems to know less of history than he used to.
