"The Brainstorm" is an episode of Wander Over Yonder.

Before one of their invasions to a planet, Peepers tries to think of ways to invade it, but Lord Hater constantly rejects every one of them, since he knows Wander will foil it. Peepers tries to think of a plan that's foolproof so they can succeed.

Episode Summary

The episode begins with Lord Hater successfully taking over a planet, Flendar, and overthrowing a king with an army of Watchdogs and complimenting Peepers for his brilliant plan. However, this turns out to be a simulation that Peepers showed him for the actual invasion later. Lord Hater gets angry at Peepers because he forgot to see how Wander would thwart him. He suggests making a new plan, then instructs Peepers to reserve a conference room and come up with a brainstorm.

In the conference room, Lord Hater opens up the floor to Peepers. Peepers suggests replacing the army of Watchdogs with Doom Dragons, who would go around the planet wreaking havoc. But Lord Hater says that Wander would thwart him by taming the Doom Dragons with "the Power of Love" and Wander would then have control of the Doom Dragons.

Peepers then decides they won't even go to the fortress, but instead suggests blasting it with an electric laser, until Lord Hater says Wander would intervene by taking the batteries to power his portable radio. Peepers says they will have backup batteries, but Hater says that Sylvia would take those as well to power her own portable radio. Peepers then says that there will be lots of backup batteries, but then Hater says all the inhabitants of the planet will use those backup batteries to power their own portable radios as well.

Next, Peepers proposes kidnapping the princess and forcing Lord Hater to marry her, but he then says the princess would actually be Wander in disguise, and now he is married to Wander. Peepers rewinds the plan and recommends kidnapping the king instead, since without leadership, the planet will end up in chaos, until Hater says that Wander will show all the inhabitants how to live in peace and harmony, and also, somehow rescue the king.

Peepers then shows the blueprints for the experimental Planetary Mind-Combobulater. He explains the device lets Lord Hater control the planet with a single thought. Lord Hater thinks about this for a while, and then responds with, "No. Banjo." Peepers questions this response, and Lord Hater explains that the frequency of Wander's banjo would match the frequency of the Mind-Combobulater, causing a huge explosion. As a result, Lord Hater and Peepers would get zapped by it, and later wake up in a fishing village with no memories. They would start life anew as fisherman, until one woman, Rosa, comes between them. They'd fight over her affection until Rosa would end up with Ron the Baker. They would end up as sad old men contemplating their lives.

Peepers suggests blocking out the sun, and Lord Hater insists Wander would save them with a group hug. Next, Peepers suggests melting their ice caps, to which Lord Hater says Wander will throw a pool party. Peepers then suggests destroying all their agriculture causing them to starve, until Lord Hater says Wander would just give out something. A Watchdog suggests, "Sandwiches?" Lord Hater agrees with this Watchdog, Bob. But Bob was simply suggesting that they get some lunch. Peepers complains there is no time.

Not even one second later, Lord Hater and the Watchdogs are all having lunch. However, Lord Hater is having both his lunch and Peepers' lunch. He then says he was probably being too negative and should be more open to the ideas of his subordinates. At first, it seems like he is asking Peepers for suggestions, but it turns out, he is opening the floor to the rest of the Watchdogs. The Watchdogs start stating some of their own ideas, one of which was suggested by Peepers earlier. Peepers gripes to Lord Hater that this is going nowhere. He then asks to pitch the plan he showed him earlier again. Lord Hater lets him go ahead.

Peepers once again pitches using the army of Watchdogs. Lord Hater asks what if Wander distracts them by dancing and Sylvia pulls their pants down. Peepers says they will be given tighter belts. Lord Hater then asks what happens if she ties the Watchdogs' shoelaces together. Peepers reminds him the Watchdogs don't even have shoelaces. Lord Hater then asks what if Wander poses as himself and orders the attack to be called off. Peepers says they will bring an x-ray scanner. Hater then becomes concerned that Wander will have a picnic and invite the other Watchdogs and because his pie is so good, they all go. Peepers says they'll have giant ants. Then Lord Hater worries they'll have a giant anteater. Peepers suggests a giant anteater eater, and so on and so forth.

Lord Hater then asks what if Wander challenges him to some carnival games. Peepers says he should ignore him if this happens. Lord Hater's concerns about Wander get increasingly more ridiculous and unrealistic, like Wander flying in at the last second and firing a shrink ray from his eyes that makes him, Peepers, and the Watchdogs teeny tiny, then Peepers shouts "He can't do that!", in which Lord Hater replies "Are you sure?" Then Peepers says they'll bring a radioactive power-absorbing crystal just in case.

Lord Hater finally becomes convinced that the plan will actually succeed, but then remembers Wander's banjo. Knowing Wander will thwart every plan, Hater calls the invasion off.

After all the Watchdogs leave, Peepers gives Lord Hater a pep talk about the fact he won't let Wander get in his way and do his usual evil things. Lord Hater is more confident now and calls the invasion back on, and Peepers asks what plan they'll use. Lord Hater suggests the first plan was good, and the invasion begins.

Unfortunately, in the end, the invasion is thwarted by Wander's banjo, just as Lord Hater predicted.


  • "Banjo"
  • "Lord Hater's Theme" (Hawaiian version. parodied as "Who is the universes loneliest evildoer?")

  • Second episode where a Watchdog besides Peepers is named ("The Little Guy").
  • Third time the title card finishes someone's sentence, second for Lord Hater. ("The Greatest", "The Hero").
  • Second episode where Wander and Sylvia play minor roles. ("The Bounty")
  • During the animatic, the "Who is the universe's awesomest evildoer" is parodied as "Who is the universe's loneliest evildoer".
  • This is the second time the infamous "Wilhelm Scream" is heard ("The Picnic").
  • Third episode where the title card's font is different ("The Pet", "The Hero").
  • The background music played during Peepers' explanation of the Mind Combobulator is the same music played during Lord Hater's monologue in "The Birthday Boy".
  • Second time Lord Hater puts Wander's abilities in high regard, while Commander Peepers does not, only to be proven wrong later in the episode. ("The Prisoner").
  • This is the second time Wander is actually shown facing Lord Hater, as seen in the part where different ant-eating species are shown, he is seen getting angry against Lord Hater's choices. The first time was in "The Day", but he was asleep that time.
  • Lord Hater calls Commander Peepers' Planetary Mind Combobulator a "Mind Comolombobulator", a "Bobcaululator", and a "Comb-over Emulator".


  • Hater mentions the times that Wander played a song ("The Birthday Boy"), had a picnic ("The Picnic") and challenged him to a contest ("The Greatest").
  • The Doom Dragon from "The Egg" reappears along with others of its kind. Lord Hater even mentions the "Power of Love" from said episode.


  • When Peepers brings out the blueprint for the Planetary Mind Combobulator, Lord Hater thinks up another scenario. When the scenario is done, the blueprint is no longer on the table.
  • During Lord Hater's prediction to the failed laser plan, he says that Wander takes the batteries and uses them for the various cassette players, but the battery compartment for the laser is really large and the batteries would be too big to fit in them.
  • The belts worn by the Watchdogs in Peepers' idea permanently disappear after just one shot of them.

  • Symphony No. 9 in D minor (Ode to Joy) - The "banjo banjo banjo" music is set to the tune of the final movement of this Beethoven symphony.
  • Star Wars IV: A New Hope - The iconic cover for Star Wars IV is referenced twice when Lord Hater and his army are defeated by Wander in both in "banjo , banjo, banjo" scene and at the end of the episode.
  • Superman (comics) - The scene where Wander flies in with a cape and uses vision based powers may be a nod to Superman. Also, Peepers suggests using a radioactive power-absorbing crystal that zaps Wander's powers and weakens him. This can be seen as reference to Kryptonite, a substance deadly to Superman, though in this instance, the red gem that was used in Peeper's plan can be seen as a reference to red kryptonite, as its traditional effects involve temporarily stripping Superman of his powers.
  • Looney Tunes - Peepers' plan of using a laser to blow up Flendar may reference Marvin the Martian in the Looney Tunes. Marvin uses a giant laser to try and blow up the Earth, as it blocks his view of Venus.
  • Dragonball Z - Specifically the original English dub where Peepers' comment about blasting Wander into the next dimension was a way to downplay a character's onscreen death.

Production Information
