After Adu Du was defeated by BoBoiBoy Cyclone and ate Yaya's Biscuits with Chemical X, he is thinking a way to defeat BoBoiBoy, so Computer said that Bago Go, the Weapon Vendor can help him, but Adu Du was surprised that all Bago Go's weapons were expensive, so Probe sold Adu Du's Spaceship to Bago Go so that they'll have the budget to claim the weapon after Adu Du fainted. When he woke up, he was shocked because the spaceship is gone and their new headquarters is now made of a chief, temporary shelter.
He first appeared near Ejo Jo when he want to buy Adu Du's Spaceship. Bago Go said "You have so much money in the bank, it's not nice to keep them a lot its such a waste if you don't spend it" and he also said some polishing, attractive words to trick Ejo Jo.
He promoted the Robey Robot XL 9000, the Fighter Jet Converter To Banana SX7650 and the ordinary core converter. He explained to Adu Du about the compatibility of cores for Probe and the budget for Adu Du to buy the core converter.
He promoted new stuff such as Homing Nuclear Weapon L9000 and Mind Raisins S900. He also contacted his friend Wak Baga Ga as a memory loss specialist to repair Probe's memory. However, when Adu Du thinks that Baga Ga is similar to Bago Go, he withdrawn the purchase from Baga Ga, requested to return the spaceship and pleading himself as Baga Ga before Super Probe shooted him.
Bago Go with the Five Scammer Commanders attack Adu Du's SampahBot with MegaBot ScamBot. Soon later, Gopal turned the moon rocks into jewelries and diamonds, made the Five Scammer Commanders forgot about the battle and chased it. When they forgot the battle, Adu Du got inside the MegaBot ScamBot and stomped on them.
Adu Du and Ibu Bu contact Bago Go to order some weapons. When Bago Go saw Adu Du, he remembered about the battle on the moon when he was stomped along with his brothers after taking over the MegaBot ScamBot while the others was playing with the luxury. Bago Go didn't want to apologize, but Ibu bu showed her Plutonium Credit Card and made Bago Go shocked. Then, he started the transaction and Adu Du decide to buy the Pango Robot to defeat BoBoiBoy.
Probe contacted Bago Go to buy a new weapon, but when Probe saw something beside the Megaton Eton Bomb X500. He saw the Superhero Jero-Jero Suit Package (Bago Go's Son birthday party costume). The price was 30 million 30 cents after discounts. Probe said that was expensive and he should buy the bomb instead. Bago Go tricked Probe by saying that the bomb has no discount, but the suit has a very big discount which was 80%. Suddenly, Bago Go's Son came and asked where was his birthday party costume. Bago Go lied by saying he didn't buy it yet, unless it's for last year and he gave his son a money to buy some ice-cream. Then Probe commented that Bago Go's Son is cute and bought two of the costumes for Adu Du.
However, it's unknown how he knew about BoBoiBoy and his friends because Adu Du, Probe and Computer never told Bago Go about him or in his case, they didn't have to.
