Builderman

Before Bobux Man Vs Gru
Builderman is the FOUNDER of ROBLOX. He was presumed dead several years before the events of Bobux Man Vs Gru.

Bobux Man Teamed Up With Builderman
Builderman pretended to work with Bobux Man. Bobux Man showed Builderman around his prison, showing him the Bobux Generator and a secret weapon which they would use to capture Gru and Monke.

Bobux Man Vs Bix Man (The Final Battle)
The location of the secret base where Gru, Monke, and Bix Man were hiding out in was made public, and Bobux Man and Builderman headed there. Bobux Man and Builderman tied up Bix Man, but Builderman betrayed Bobux Man and shot him. Then Bobux Man and Bix Man both used their powers to destroy each other.

Gru Teams Up With Builderman
Builderman headed into the secret weapon and flew it towards Gru and Monke, who were flying on the Bobux Generator. They crashed. Gru and Monke headed back to the base, and tied up Builderman, interrogating him. Builderman explained that he had betrayed Bobux Man and that Bix Man and Bobux Man used their powers to destroy each other. Gru untied Builderman, who explained the plan. The plan was to use the Bobux Generator to recreate Bobux Man and Bix Man. However, the Bobux Generator stopped working. Monke said he knew someone who could help, and so he dialed his father, Monke Father. Monke father agreed to help, and everyone headed to the jungle. Monke Father said to ask the Monke King, saying he was friends with Bobux Man when Gru asked why. Gru and Monke headed off to ask the Monke King while Builderman stayed with Monke Father.

Monke Father Betrayed Everyone
Builderman asked what Monke Father did for a living. Monke Father ate some coconuts and asked if Builderman had said anything. Builderman said "never mind." Monke Father began typing on his computer. Builderman thought that that was very sus of Monke Father to do. Builderman decided to take a walk as it was so beautiful in the jungle. Builderman found an AMOGUS BOBUX CARD lying down in the grass and picked it up, shocked and happy. Suddenly, two AMOGUS captured Builderman. It turned out Monke Father had betrayed Bobux Man for coconuts.

Builderman Escapes the Jail
Builderman let the AMOGUS take him to the secret base before asking to go to the bathroom. He then beat up one of the AMOGUS and stole their costume. However, the other AMOGUS was suspicious of him and the two battled it out with a game of amogus. Builderman won, and found Monke Father, helping him defeat other AMOGUS. Builderman forgave Monke Father, and the two began plotting to save Gru and Monke.

Monke Father Finds Obamium
Monke Father and Builderman head to the prison where Gru and Monke are being held captive. There was a massive forcefield powered by bobux. Monke Father and Builderman went to find a powerful substance known as Obamium. When they get there, Obamium and Monke Father fought in a game of Friday Night Funkin' battle. If Monke Father won, he would become Obamium's owner. If Obamium won, Monke Father would become Obamium. Builderman advised against competing, but Monke Father did it anyway. Monke Father won, and the three of them headed off.

Monke King Captured Everyone
Monke Father was killed by a train as they crossed the railroad, making Builderman sad, but Obamium revived him using their powers. Monke King and two AMOGUS came, trying to capture the three of them. Obamium tried to fight back, but they had used up all their powers reviving Monke Father. And so they were all captured.
