"Robots From The Sky Part 3" is the eightieth episode in the Sonic Boom television series. It first aired on 9 April 2017 in France and on 20 May 2017 in the United States.


Sonic and Tails discover that the city in the clouds has been taken over by evil robots, and it might all be Tails’ fault![4]



Races and species:






The episode begins where the previous episode ended, with Sonic and Tails inspecting the ruined Morristown. After the two note how depressing the city looks, Sonic decides they should go for a stealthy approach, knowing the situation hinges on it. This plan is instantly ruined the minute Sonic trips an invisible laser, sounding an alarm that attracts robots to their location. Tails scans them and notices they are infected by the same malware as that of the other robots, believing them to be Morristown civilians and saying they should not be destroyed.

The two run further into Morristown as the robots give chase and blast at them with laser weapons, but they eventually come to a dead end. Fortunately, there is a chute at the end of the corridor from which a voice tells them to get in. They are grabbed by stretchy arms, at which point they slide down and end up in another room where they are suddenly surrounded by robots. However, Mighton, who is in the room as well along with Bolts, tells them to stand down, informing them that Sonic and Tails are allies.

Mighton and Bolts explain that Mighton was made leader of the Robot Resistance, and that a surface bot in the city sent out a signal for miles that hypnotized almost all robots, explaining the sudden uprising. They would like to solve the problem themselves, but if they leave the safety of the lead-lined bunker, they will instantly fall under the perpetrator's control; Sonic and Tails, being immune, offer to do the job for them and, after being told the perpetrator's location is in the city's Central Power Core, are handed a map to help them get there. Meanwhile, in the Village Center, the villagers are under siege from the malware-infected robots attacking Hedgehog Village, with the other three members of Team Sonic-- Knuckles, Amy, and Sticks—attempting to fight them off; even Og eventually arrives to lend a hand. Sticks cannot believe that a deadly robot that is attacking them such as FriendBot could have such a name, but Amy tries to assure her that he has got a great personality.

Back in Morristown, Tails is attempting to follow the map to the core, but everywhere in Morristown looks the same, and Sonic wishes for a simpler way to get there. Suddenly, an alarm blares and a group of robot guards arrive to capture them and take them to the core. Sonic and Tails exploit this, surrendering without a fight, and they are taken to the core, where the robots inform their leader of their capture. Said leader is revealed to be Hypnobot, now capable of speech; Tails is surprised at this, remembering he never programmed Hypnobot to be sentient, and Hypnobot begins to explain how it happened. He recalls his initial creation to participate in a robot-fighting tournament and his later defeat by a poodle robot; the explosion from the latter hurled him into space, where he drifted for weeks waiting for Tails to rescue him until a Morristown sentry found him and brought him to Morristown. There, he was repaired and enhanced, granting him sentience, and thusly, the ability to realize Tails betrayed him. As such, he hypnotized most of the population of Morristown (which he believes needs a better name) so the city would act as his stronghold, and then the rest of the world's robots to destroy organic life.

Tails attempts to apologize for not realizing Hypnobot needed him, only to have said apology harshly rejected; he then tells Hypnobot to leave everyone else out of this, knowing it is him he really has an issue with, and Sonic calls Hypnobot out on hypnotizing the people who repaired him. Hypnobot, after turning the latter statement into an insult to Tails, orders his robots to attack, and the two have trouble dealing with their numbers. Meanwhile, in the Village Center, Knuckles, Amy, and Sticks continue to battle the invading robots, also having trouble dealing with the sheer numbers by themselves. The villagers continue to watch as they struggle, but a speech from Knuckles about protecting their personal belongings inspires them to stand up and fight, assisting the three in the battle to save the Village.

Returning to Morristown, Sonic and Tails continue to fight off Hypnobot's guards, and Tails notices Hypnobot running away and gives chase, with Sonic following after breaking free of the guards. When the two are surrounded by more of Hypnobot's guards, Sonic proposes the only way to stop them is taking out Hypnobot before shoving his way through them, one of which drops his weapon; Tails picks it up, flies into the air, and takes aim at Hypnobot, but hesitates to fire, unable to bring himself to destroy one of his own creations. Hypnobot fires a bola from a gun which, while not hitting Tails directly, causes him to fumble the weapon and accidentally fire a shot that blows a hole in Morristown's protective glass dome. One of Hypnobot's guards kicks Sonic in the back of his left leg, injuring it, and Tails gets his tails tied up by another of Hypnobot's bolas and falls out of the hole, barely managing to grab the city's lip as Hypnobot laughs in triumph. Sonic, in spite of his injured leg, runs over, kicks Hypnobot off the edge of Morristown, and grabs Tails' hand just as he loses his grip; however, one of the robots stomps on said leg, injuring it further.

Hypnobot plummets into a frozen lake, breaking his hold over all robots and thus ending the invasion in the Village Center, with all of the robots abruptly retreating. Knuckles, Amy, Sticks, and the others celebrate their victory (though the villagers do not stay to clean up the mess). Back in Morristown, as Sonic struggles to pull Tails up, the formerly hypnotized guards also relent, and Mighton and Bolts meet back up with the two, with Bolts helping Tails back up. Meanwhile, in Eggman's lair, a cereal-eating Eggman mopes about his robots leaving him when suddenly, his radar shows the robots coming back and, to his surprise, one other signal.

In the lead-lined bunker within Morristown, Sonic is getting his injured leg braced sloppily with duct tape, and Tails expresses his guilt over the whole situation, knowing that his creating and inadvertent abandonment of Hypnobot caused the uprising and that Sonic would never have gotten his leg injured had he not hesitated to destroy him. Sonic, while noting Tails makes a good point, reminds him that at least the whole issue is over. Unbeknownst to them, Eggman is investigating the signal he received in the icy lake inside a water-protected Eggmobile, where he finds the now-frozen Hypnobot and plucks him from the ice using the Eggmobile's claw; he welcomes the robot to his team before laughing maniacally (with Knuckles once again growing impatient with the cliffhanger ending after the fade to black).




The concept for the "Robots From The Sky" story arc (sentient robots coming from a floating island in the sky) was formulated by Bill Freiberger.[5] The story arc itself came out of a desire to tell a longer story and "get extra mileage out of production concerns like new characters and locations."[6]

When voicing Hypnobot for this episode, Travis Willingham tried to emulate Shere Khan's voice.[7] Also, Mighton's stint in "Guatamañana" was added as a callback to "Tails' Crush" (Guatamañana was the location Eggman's package got rerouted to in that episode).[8]

Originally, the scene where Bolts patches up Sonic with duct tape was written as the first scene of "Robots From The Sky Part 4" during production. However, it ended up as a part of this episode for unknown reasons.[9]
