Yoyo Oo

Yoyo Oo is an alien from the planet Ata Ta Tiga. He is one of the members of the notorious Tengkotak group.

BoBoiBoy: The Movie
Bora Ra with his team members are hunting Klamkabot on Floating Island. Seeing Klamkabot fled, Bora Ra ordered Yoyo Oo to launch Robot T. A group of yellow robots were seen coming out from under the spaceship and they caught Klamkabot from every angle and buried their feet in the ground to stop Klamkabot's movement. Bora Ra was satisfied with that and ordered his team to lift Klamkabot into the ship. Klamkabot anxiously immediately scanned the existence of another nearby Power Sphere and discovered Ochobot who was on Earth. Then Klamkabot uses the rest of his Teleportation Power and fled himself (with the island) to Earth, making Bora Ra howl with all his heart in space.

Later, Bora Ra finds out from Yoyo Oo that he managed to locate Klamkabot's last location on Planet Earth but his location is unknown. Dissatisfied with the report, Bora Ra threatened to search for Klamkabot's place or be kicked out of his spaceship, causing Yoyo Oo to immediately search for Klamkabot's place. After performing what it takes to track down, Yoyo Oo finally finds Ochobot's signal and 'informs' it to Bora Ra. So Bora Ra instructs Kiki Ta to speed up the spaceship so that they can arrive on Earth before Klamkabot manages to gather his Teleportation Power again.

At Tok Aba's Kokotiam, when Gopal invited his friends home, the Tengkotak spaceship arrived and landed at Rintis Island. His arrival was welcomed by Adu Du and Probe, then introduced them to BoBoiBoy for not knowing them. Bora Ra expressed his desire to take the Power Sphere (Klamkabot), and angered when he found it was Ochobot, not Klamkabot. Yoyo Oo tells the truth, then finally suggests to catch Ochobot and use him to find Klamkabot as he has been contacted by him before.

Bora Ra then asks permission from BoBoiBoy to 'borrow' Ochobot, and without wasting time seize Ochobot and hand it over to Yoyo Oo. Yoyo Oo handcuffed Ochobot inside the Power Sphere Grinder and allowed their spaceship to receive Klamkabot location signals. Seeing Ochobot captured, BoBoiBoy immediately transforms into BoBoiBoy Thunderstorm and rushes towards Bora Ra, but is stopped by Gaga Naz. BoBoiBoy immediately split into three and opposed Gaga Naz, but eventually lost and they reunited. Gaga Naz then fights with Yaya, Ying and Gopal before asking permission from Bora Ra to transform when his defense is insufficient.

However, Bora Ra rejects his desire and produces a Black Hole that begins to suck up everything in Rintis Island Park including Yaya, Ying and Gopal and messes up everything. Bora Ra then stopped the black hole. With Ochobot already in his hands, Bora Ra along with Gaga Naz and Yoyo Oo return to the spaceship.

Afterwards, Tengkotak, Adu Du and Probe head to Floating Island, using Ochobot to track the location of Klamkabot. Adu Du and Probe had time to remind Bora Ra that BoBoiBoy would definitely go save him because he and Ochobot were friends like them. It made them laugh at them causing Adu Du to get angry and then say they were cruel. After realizing that BoBoiBoy was heading to Ochobot, Bora Ra and Yoyo Oo handed Kurita to Adu Du and Probe, then threw them into the sea. After being exposed to water, Kurita grows into a giant robot squid that goes to attack them, along with BoBoiBoy and his friends.

When Tengkotak landed on the Floating Island, Yoyo Oo took control of Ochobot to find Klamkabot in the caves. The search lasted for hours and when Yoyo Oo felt drowsy, Klamkabot attacked Ochobot, tapped his control and startled him. Under the direction of Bora Ra, Yoyo Oo sends the coordinates of Klamkabot's last location to him and J-Rex to hunt down BoBoiBoy and his friends, who arrive on Floating Island.

When BoBoiBoy and his friend discover Klamkabot and Ochobot, Klamkabot reveals that he has escaped from Tengkotak, who is hunting him for his teleportation power. They want it to spread their power faster across the galaxy, allowing them to conquer more planets than ever before. They are interrupted by Bora Ra and Gaga Naz, who later chases them in the Power Sphere Factory. Bora Ra manages to capture Klamkabot, while BoBoiBoy and his friends, including Ochobot, escape.

As soon as they brought Klamkabot back to their spaceship, they forced its teleportation power by force, only to find it empty. They realized that Klamkabot had given his teleportation power to Ochobot. Yoyo Oo manages to track Ochobot's position and finds out that he never escaped from Earth. Bora Ra threatens BoBoiBoy to hand over Ochobot or his friends Papa Zola, Adu Du, Probe and Klamkabot will suffer.

BoBoiBoy and his friends go to the Tengkotak Team, and agree to hand over Ochobot. However, it later revealed that they planned to teleport themselves and their friends from the Tengkotak. Before Ochobot was able to continue the teleportation, Kiki Ta fired shots and ruined their plan, revealing that they already knew their plan.

Bora Ra forcibly sucks Ochobot's Teleportation Power and fights against BoBoiBoy, who is later joined by Fang. Gaga Naz attacks Yaya, Ying and Gopal, while Yoyo Oo and Kiki Ta try to capture Papa Zola, Adu Du and Probe, who have boarded the spaceship. When Bora Ra destroys Ochobot with Black Hole Compression, Ochobot gives his last energy to BoBoiBoy and his friends who upgrade their power. The improvement gave them a second level and they managed to beat their opponents.

Meanwhile, Papa Zola, Adu Du and Probe are eventually tied up by Kiki Ta and Yoyo Oo, but are later rescued by J-Rex who is released from captivity.

At the end of the film, Cici Ko reveals her true identity and binds Gaga Naz, Kiki Ta and Yoyo Oo and takes them into space. The final credit shows Cici Ko / Koko Ci imprisoning Gaga Naz, Yoyo Oo and Kiki Ta.

Personality
Yoyo Oo is always cheerful and obeys the instructions of his captain, Bora Ra. However, Yoyo Oo is often negligent and careless while performing the tasks assigned to him. Yoyo Oo is also a coward when he is often scolded by Bora Ra for his negligence. Because of his actions, Yoyo Oo was once threatened by Bora Ra that he would be thrown from Tengkotak spaceship if he did not give what his captain wanted.

In addition, Yoyo Oo also did research on the powers of the Power Spheres in his laboratory located inside the Tengkotak spaceship. To assist in his research, Yoyo Oo underwent the process of upgrading his thinking power by replacing his brain with a sophisticated computer system. Computers placed in special jars on their heads have special systems to prevent them from competing with each other. The jar is also very strong and has a low temperature to further optimize the processing power of the computer system in it.
