Dr. Locus appears for the first time in Bradventure. Growing tired of always being on Jenny's shadow, Brad decides to go on a journey to prove himself as a hero but during his way he encounters a hideout that leds him to Dr. Locus' lab where the scientist was fixing his recent destroyed robotic farm animals that previously attacked Tremorton just when he notices Brad sneaking in who runs away and demands him to come back as his robots go after Brad. During his way out of Locus' hideout, Brad meets a teenage girl called Melody who takes him to meet her father who turns out to be Dr. Locus himself. The old man presents himself to Brad as a gentle and caring person who created several farm robots that he wants to experiment to improve them as possible. Brad has his doubts of trusting the doctor as he says one of his pig robots attacked tremorton to which Locus explains it may be the testing of flying ability until Brad mentions that Jenny had to stop them which immediately caught Locus' attention who asked him if he knew Jenny and indeed was Brad's friend so Locus asks him if he could call her to come to his laboratory but when Brad insists he should leave, Locus finally reveals his true colors when he traps Brad in a giant cage. While Melody is confused, Locus explains that his main goal is to get Jenny's schematics to complete his evil plans that he refuses to tell and leaves taking Melody with him.
Later on after rescuing Brad, Jenny is suddenly electrocuted with a collar put by Locus from behind after Brad escaped to the surface, who meets Melody telling him that her father has captured Jenny. On his laboratory, Dr. Locus has already made a CD copy with Jenny's schematics just when Brad and Melody enter in, but Locus demands Melody to obey and come with him. Although feeling uncertain if he would do it, Brad tells Locus to release Jenny, only to be responded by the mad scientist releasing Jenny commenting that he already has what he needed from the start but reveals that he can't let both teenages leave now that they know his secret and activates the hideout's destruction sequence before escaping with Melody.
After Jenny and Brad successfully escaped in time, it's revealed that Melody helped with her robotic extended arm, revealing herself as one of Dr. Locus' creations who comments that once he equips Melody with the weaponry of Jenny's, she will become the most powerful robot the world's has ever seen, and Melody (uninterested) agrees.
