Jerry (Milo Murphy's Law)

"You wish it was Milo!"

- Jerry interrupting his father while taunting Sara Murphy upon his arrival.

Jerry is the secondary antagonist of the Milo Murphy's Law special Missing Milo. He is a Pistachion who serves for his father King Pistachion.

He was voiced by Dee Bradley Baker, who also voiced his brother Derek.

Origins
Although Jerry did not appear much in the first season, his origins were shown in the episode "The Substitute", where Milo Murphy and his friends accidentally created a sentient blob that attacked the students and two time-traveling agents named Vinnie Dakota and Balthazar Cavendish. In the end, the blob left the school and came into contact with a broken pistachio sapling on the lawn, causing it to be replenished to its former glory and resulting the birth of King Pistachion, who would breed his own army of Pistachions (including Jerry) to take over the world.

Role
Jerry was known for helping out his father and their fellow Pistachions in taking over the world in the year 2175, though he tends to ruin every time his father tries to monologue to his enemies, much to his guilt.

Following the successful capture of the majority of the people (including Mr. Block, the head of the Time Bureau), Jerry was seen among cheering with her fellow Pistachions as King Pistachion declares the entire world to be under their control. As King Pistachion declares that he will take a picture as a memento, he notices three humans (Milo Murphy, Balthazar Cavendish and Vinnie Dakota) on the background as they have avoided captivity. As such, King Pistachion orders Jerry and the others to get the trio, but the trio managed to get into their time machine to escape, prompting an annoyed King Pistachion to use his own time machine to stop them.

Jerry was chosen among several of his brothers to tag along with their father to travel back in time when King Pistachion was just a seedling growing in the lawn of Milo Murphy's school. Upon the Pistachions' arrival witnessed by Sara Murphy, Melissa Chase and Zack Underwood, Jerry instantly spoils another one of his father's expositions, much to the latter's anger. However, King Pistachion continued on with the monoglogue of his fellow Pistachions, even admitting that he took a picture of Jerry's birthday party in his phone. As King Pistachion ponders over his seedling form, he orders Jerry and the others to kill the kids, though Milo, Cavendish, and Dakota arrived to the rescue.

As the Pistachions fight against the heroes, Jerry started chasing Sara, only to end up being knocked into the school billboard with an inflatable raft by Melissa. After Milo gets his dog Diogee to pee on the pistachio seedling, King Pistachion and the rest of the Pistachions fade away from existence, and Jerry is last seen rearranging the letters to form the phrase "Jerry was here" on the billboad, just as he fades away from existence.
