Probe
- Affably Evil: Probe is genuinely well-mannered, jovial, easy-going and comical, making him a great example of a foil of his boss, Adu Du.
- Anti-Villain: The reason why he is so loyal to Adu Du is because he saved him in the past when his creators rejected and threw him away.

Having pity for him, Adu Du decided to rebuild him and made him his most loyal minion and friend.

- Literal-Minded: When Adu Du announced from outside BoBoiBoy's house that he had a present to give the latter, once Probe got clarification that the "present" was the Sleeping Monster, he proceeded to enwrap the monster in a colorful present box offscreen. This led to a Failed Attempt at Drama on Adu Du and the Sleeping Monster's end.
- My Master, Right or Wrong: He always follows Adu Du's orders without asking too many questions.
- Mind-Reformat Death: Subverted. When Probe came back to life after Adu Du successfully converted the energy from the P.E.T.A.I. robot's core into Probe's core, Probe acted as if he were on his initial battle robot programming with no memory of his master, just the initiative to serve him. It takes throwing a mug at Probe's head to make his memories come back.

- Paper-Thin Disguise: He disguised himself as "Auntie Saodah" when he and Adu Du attempted to steal cocoa powder from BoBoiBoy's Granddad. Although both Gopal and Granddad were suspicious at him at first, they were still foiled by their disguise. Others weren't as easily fooled.
