"The Return of Robotgirl" is the 103rd episode of the series and the 13(a) of Season 4 of Robotboy. In this episode, the gang were having a sleepover in their tents, until they suddenly see something fly bg and hit the top of a hill and find a little mechanical pod which Robotgirl is inside. Robotgirl was sent from Moshimo to tell them that he's in danger and he needs their help.


Robotboy’s friend and fellow creation of Professor Moshimo, Robotgirl, arrives at Tommy’s suffering from memory damage and bearing a distress message from Moshimo. When Tommy and Robotboy finally manage to get her to lead them to Moshimo, it turns out they’re walking right into a trap set by another Moshimo creation: Protoboy, who seeks to lure his fellow robots to their doom.


At a night at Tommy's yard, he and his friends are having a sleepover in thier tents. When the boys where making shadow puppets they suddenly get frightened by a little spider and run inside Lola's tent. Gus prefers not to be inside since he finds Lola's tent too girly and he makes Tommy and Robotboy leave the tent.

Suddenly, something from the sky crashes on top of a hill and the boys take a look. They find a mechanical pod, Tommy opens it up and inside they find a little pink robot which is Robotgirl. They activate her and she plays a holographic message. In it, Professor Moshimo, in a hurry and in danger, urgently tells Robotgirl to tell Tommy something. Tommy suspects that Moshimo is in trouble while seeing if Robotgirl can help them find him. Unfortunately, she seems to misunderstand their question due to her emotion chip being broken and punches Gus for no reason.

At Tommy's bedroom the boys are trying to fix her, until Gus insults Robotgirl, causing her to cry. When Robotboy comforts Robotgirl he makes fun of Gus and Gus gets mad and they start arguing at each other, scaring Robotgirl. Suddenly, Lola appears and comforts Robotgirl and takes with her to her tent. Tommy reminds Lola to ask Robotgirl to find out about Moshimo.

After Lola has comforted Robotgirl and tells her to ignore her logic functions and instead listen to her emotions, the gang starts to look for Moshimo and arrive at an abandoned Titanium Factory. They start looking until they find Moshimo inside a tube where he is held hostage by Protoboy. Protoboy demands both Robotboy and Robotgirl enter the molds so they will get frozen inside a titanium liquid so Protoboy can be the only robot of Moshimo's and he'll let him go. Robotgirl approaches up to one of the molds but Robotboy stops her and he gets caught inside one instead. To which Protoboy mocks him for. He then tries to convince Robotgirl to do the same, but Professor Moshimo tells her not to do it, but Robotgirl doesn’t change her mind. Tommy then says that Protoboy was lying, Robotgirl responds that her logic functions read "Save Moshimo", but her emotion chip says that Protoboy is lying, so she flys up to fight him. Protoboy then activates the titanium machine and then he fights Robotgirl.

At the same moment the kids try to figure out an idea to be able to free Moshimo and Robotboy from being dipped. Protoboy defeats Robotgirl by kicking out her batteries which deactivated her and almost kicks her into the burning liquid when Lola interrupts him by telling that Moshimo has another robot that he likes more then him and it will beat him up. While Protoboy prepares to fight the other robot Lola frees Moshimo and Robotboy. Protoboy finds out that the "robot" is an illusion made by Tommy and Gus and prepares to shoot them, but gets blasted by Superactivated Robotboy with rockets and falls onto the bridge. He tries to shoot Robotboy and Moshimo, but Ro blasts him a second time and the the bridge, causing it to collapse, Protoboy nearly falls into the liquid, Robotgirl nearly falls into it too, but Robotboy and Moshimo save her just in time. The liquid starts to destroy the whole factory but Robotboy saves them all at the last second by carrying them on a piece of rubble as the factory explodes, leaving Protoboy's fate unknown (according to Jan, he survived).
