Original Appearances: “Peabody's Improbable History” segments of Rocky and His Friends
Other Appearances: Same segments on The Bullwinkle Show as well as all kinds of merchandise
Biography: Mr. Peabody is a scientific genius who adopted his boy, Sherman, for company. Realizing that boys need running room, Mr. Peabody invented the WABAC Machine in order that they could travel back in time and participate in historical events – although these historical events tend to be a bit cockeyed compared to what's taught in schools. At the conclusion of each historical adventure, Mr. Peabody makes a pun about what's happened that makes Sherman wince.
Powers: Ability to speak, uncharacteristic of other dogs in his reality, apparently
Group Affiliation: None
Miscellaneous: One of my favorite Bullwinkle segments, and it's fun how they turned the whole "boy and his dog" thing around!
