Analogs of Donald Trump in Science Fiction

Aslan? He’s big and predatory and has a mane of golden hair. Difficulty: He's not the Son of God.

Hober Mallow? Some people might think so but he's not rich enough.

Henry Belt? He might look lazy and irresponsible and act like he's lazy and irresponsible but don't let that fool you. He really is lazy and irresponsible.

Zaphod Beeblebrox? Close, but he doesn't have two heads.

Lord Brodrig? Lord Brodrig had to be loyal to the Emperor because he was the most hated man in the galaxy. Trump has to be loyal to the right wing because they'll be the people keeping him out of jail, but only if he does everything they want. (Nixon forgot about that part.)
