Robie Prime lives in planet Excite Prime, with his parents Optibus Prime which is the king of the Excite Prime and her mother Queen Merlita Prime. Planet Excite Prime is a planet inside the Milky Way near the Planet Pluto. The Robots in the Planet Excite Prime looks exactly as humans, but instead of bloods and internal organs, Robots in Excite Prime have electricity, wires and batteries. They can also turn their hands and other body parts into weapons and other things they needed. Unlike his father, Robie is weak. He runs out of battery so quick and he can't even transform his hands into any weapon. One day his father King Optibus Prime was accused of corruption of power sources. Because of this his father was dethroned and his father's rival Negatron takes the throne and now serves as the king. Negatron is a boastful and full of greediness inside his wires and tubes of his body, but the truth is, he is not brave and great as the former king Optibus. Even it isn't true, the Prime family was kicked out of the palace. The Royal family turns now into a poor family with few sources of power. On the other hand Robie still manages to go to school even with difficulties in financial support. While walking in the pathway, everyone was talking and gossiping about him, they were like " So he is the Son of the former king, the king of corruptions". Each day Rob gets bullied, since he is weak he can't even protect himself from these bullies. Despite of all the robots saying he is weak, Rob trains every day and even at night as long as he can. His father always told him not to quit, telling him that someday he will be a hero. Robie did what his father says, he never quit. He endures all the pain of being bullied. Randy one of his major bully, tease him all the time. Every time Robie enters the classroom Randy always says," Ladies and Gentlemen, let us all welcome the weakest of all time and the son of the King of Corruption, Robieeeeeeeeeeeee the weakest", and every one laughs at Robie. Suddenly a loud sound of thunder turns their laughs into fears. A large asteroid hits their palace. A huge monster with 6 heads and a dragon like body. The guards of the palace immediately response and tries to kill the monster but nothing could penetrate to its skin. The king immediately hid himself into his cabin while crying and shaking in fears. The monster kills and destroys anything on its way, and it is now heading towards the school. Every student's starts to panic now, Randy the bully, push every one even the girls and younger ones just for him to escape. Everyone rushes to go out but not Robie. He is not afraid, he wants to protect everyone even those who bullied him. Everyone already had evacuated the school and Robie remains on the rooftop, ready for the fight he is about to enter. The monsters tail attacks Randy while running, when the tail is about to hit Randy a shield stopped it. Everyone stops and saw Randy turns his hands into a shield to protect Randy, the one who always bullied him. Randy doesn't even thank Robie for saving him. Both of them runs away from the monster, Robie ask Randy to help him kill the monster, but Randy refused. The monster is about to catch them, so for Randy to escape he bumps Robie, so that he will be able to escape. Robie fell down and the monster is about to stab him with its tail, Robie uses his shield one more time to protect himself. But the shield can't hold any longer. The shield is about to crash. Then a sword cuts through the monster's tail. It is the former King, Optibus Prime. Robie gets up and with a smile in his face. Now both of them fight's the Monster. However once a head or a part of the body is cut, the part which is cut multiplies. So for each head that is cut, two more heads will grow on the monster body. The monster is getting stronger, Robie gets knocked down by one of the monster's tail. While his father is busy handling 15 sharp tails trying to stop him from helping Robie. Robie is about to be stabbed by one of the monster's tail. Optibus rush to his son with all of his energy, Robie just closed his eyes with both of his hands and feet tied by the monster's tail and accepts that he is about to be killed by the monster. But nothing happens to him so he opens his eyes and saw his father gets stabbed by the monster. Robie cries and and was covered in anger and madness, wanted to take revenge for his father. No one still helps Robie and his father, every one remains afraid and just watch while his father dies. Robie still keeps on fighting even with low energy, he gets knocked all the time but he still keeps on fighting and remembering what his father says "Don't quit". Robie is about to run out of battery, he keeps on pushing himself to his limit. Until a laser hits the monster, it is from one of his neighbor, then everyone follows and uses all of their weapons to kill the monster. All of them in the Planet Excite Prime joined their forces together to defeat the monster. Robie has a mixed emotion, sadness for his father's loss and happiness for what they have done. They have successfully killed the monster through every one's help. The king showed up when everything was cleared and safe. All the robot's bashed him and tells him that he is a worthless king. Randy the bully yelled " Robie Prime as the king " and everyone follows and yells Robie to be the king. Negatron was dethroned and replaced by Robie. Everyone feels sorry for what they have done for Robie, for accusing his father and dethroning it, and for Robie getting bullied all the time. Robie forgives all of them, and her mother Merlita Prime was so proud of what he had made for their planet. Robie is now considered as the greatest hero of Excite Prime, Robie the weakest is now Robie the King.
