According to this guidebook, which describes events after Atlantis: The Lost Empire, Theodore Roosevelt was one of the regular visitors to Atlantis, along with other celebrities such as Edgar Rice Burroughs, H.G. Wells, and Harry Houdini. He was brought there in secret by Whitmore Industries.
Theodore Roosevelt appears in the episode Tarzan and the Rough Rider where he visits the jungle on safari and runs afoul of kidnappers. At first he does not impress Tarzan who does not see him as being a worthy leader, but Theodore manages to prove otherwise later. Here, he is voiced by Stephen Root.
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. Bringing in the army and after a comical battle, Theodore recognizes his old friend Scrooge and the two stop the fighting and get reacquainted while having a campfire dinner.

Roosevelt has been depicted in many Disney-owned Muppet productions as part of Mount Rushmore with Thomas Jefferson, Abraham Lincoln, and George Washington. Roosevelt frequently utters cries of "Bully!" He was performed by Frank Oz in The Muppet Show: Sex and Violence. Fozzie Bear played "Teddy" in a 2014 Presidents Day video posted on Walt Disney Studios' Facebook page, promoting Muppets Most Wanted.
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.
