Theodore Roosevelt appears in several chapters of the storyline. In The Buckaroo of the Badlands, set before his presidency in the year 1882, he befriends Scrooge McDuck and helps him defeat a group of cattle rustlers. Years later, in the chapter The Invader of Fort Duckburg, Roosevelt is called in by the Junior Woodchucks to reclaim the ruins of Fort Duckburg, which Scrooge McDuck purchased to build the Money Bin.

In the Phineas and Ferb episode, Mandace, Heinz Doofenshmirtz was changed into Theodore Roosevelt. And in Steampunx, a teddy bear is modeled after Roosevelt, apparently due to his presidency being in that time and the teddy bear was named after him.
