After the destruction of TAPOPS Station from Retak'ka's attack, BoBoiBoy and his friends return to Earth to await their next mission while continuing their studies. Unexpectedly, an old foe returned with new evil tricks up his sleeves.

Planet Rimbara is a former colony of King Balakung, the original wielder of the Elemental Power of Darkwood/Timber who died at the hands of Retak'ka. A planet filled with jungles also holds many secrets. Can BoBoiBoy unravel the secrets of King Balakung and obtain the Elemental power of Timber?

BoBoiBoy and friends return to Tuan Guru Gaharum only having 2 ingredients. However, BoBoiBoy was given another chance to prove his seriousness. Their journey in Rimbara is nearing its end, but only one will be crowned champion. Who will inherit the knowledge of Sir Guru Gaharum from generation to generation? BoBoiBoy or Qually?

After receiving the Oakuat seed from Master Gaharum, BoBoiBoy is now eager to learn his Third Level Elemental Power. But BoBoiBoy's plan was successfully sniffed out by a cunning and scheming enemy. The fight between these two enemies leads them to a savage and wild world: Planet Kadruax!

After encountering the Tumbosar hordes on Planet Kadruax, BoBoiBoy and his friends try to escape in order to track down the valuable Power Sphere PasuBot that can help BoBoiBoy achieve his Third Level Elemental Power. But there's another surprise waiting for them in the wilderness of Kadruax, which could throw their plans into disarray!

BoBoiBoy Solar, BoBoiBoy Thorn, and Ying are in the Stone Pyramid, where the Power Sphere PlanterBot is stored. However, BoBoiBoy Thunderstorm, Gopal, and Yaya are still looking for a way to escape to avoid becoming prey to the Plantosaurs. Can they save PlanterBot before Adu Du and Probe? Or did Adu Du manage to acquire the Power Sphere and release the latent power within him?
