Prepare to face the wrath of the mischievous Dr. Screwball Jones!
~ Dr. Screwball Jones.

Dr. Screwball Jones is a character from Disney's Wander Over Yonder, first appearing in Season 2 as the main antagonist of the episode "The Boy Wander".

He was voiced by Weird Al Yankovic.


Dr. Screwball resembles a floating yellow banana with a clown wig, a pink nose, a red bow tie with white polka dots, a black top hat, black glasses, and a doctor's head mirror. He also has a large black mustache which also take the place of arms.


Screwball Jones is similar to Wander, in that he wants to make everyone in the universe happy. However, he is maniacal and certifiable, so he plots to force everyone in the universe to be happy by taking over it, which clashes against Wander's more care giving nature. He is fond of puns and is able to create them with ease. He is very insistent and vociferous of his doctoral status and is able to realize when a situation is ironic. He admires polka music and is quite fond of the accordion. He is unable to resist a good gag and will not pass up a chance to use it to make as many puns as possible, even if he is on the verge of victory.


Wander mentions Dr. Screwball as being a villain of his past. Like Wander, his goal is to spread joy across the universe, but does so by forcing people to laugh, which Wander is against since he believes happiness is meant to be found freely. Screwball is known to constantly tell jokes and his schemes involve practical joke materials.

The Boy Wander

Telling by a missing feather and a whoopie cushion, Wander realizes his old foe has returned. Going undercover, he goes on a quest to take down Screwball. The villain, meanwhile, steals feathers from a museum and an alien race. He later introduces himself, revealing to have created a tickle machine, which he inflicts on an entire planet, as well as Lord Hater and Commander Peepers. When Sylvia falls victim to Screwball, he and Wander engage in a musical duel/confrontation. Just as all hope seems lost, Sylvia manages to break Screwball's machine, causing it to backfire on him as his blimp is sent away.

The Battle Royale

In this double-length episode, Screwball appears as one of the many villains who have come to battle over a supposedly powerful ring. He tries to attack Wander but is defeated once again.

Abilities and Powers

  • Hat Mechanism - Screwball can summon multiple mechanical hands and he used them many times from his hat. The hands themselves vary , from two hands in which they throw pies at Wander, to a buzzer that zaps him. He also uses them for extra dexterity.
  • Concertina Efficiency - Dr. Screwball Jones is an expert at the concertina (or accordion), and he can especially be able to shoot out shoot music note-filled beams when played. The amount of the beams can extend a bit, as seen when he and Wander had a short "banjo and accordion" showdown.



  • According to Wander, Screwball is the most diabolical villain in the galaxy, even more so than Lord Hater & Lord Dominator.
  • He is the first villain to be treated as an actual threat by Wander.
