During Ejo Jo's attack, Probe was destroyed and Adu Du lured Ejo Jo into his base to avenge Probe. After successfully driving away Ejo Jo, Adu Du attempts to fix Probe but failed.

Probe imagines himself a living creature and does things that humans do like humming and sleeping. In Season 2, he was destroyed by Ejo Jo's battle robot to protect Adu Du. He was revived in Season 3 which comes along with a new form called Mega Probe but suffers from temporary memory loss, but was later fixed. |

| Ochobot | Muhammad Fathi Bin Diaz | The Generation 9 Power Sphere found by Adu Du. Initially mistaking BoBoiBoy as its master, Ochobot grants BoBoiBoy his Elemental Power Watch before his friends and Fang in the second season.
