~ Derek after turning the families and friends of Milo, Phineas and Ferb into Pistachions.
No! It can't be, it was working!! We had WON!! How could it all go SO WRONG?!! (Milo: Well, that's Murphy's Law for ya.) RAAAAH!!!
~ Derek's last words before his death.

Derek is a major antagonist of the Disney XD series Milo Murphy's Law. He served as a supporting antagonist in the hour-long special "Missing Milo", and the main antagonist in the episode "Fungus Among Us" and the hour-long special "The Phineas and Ferb Effect".

He was a Pistachion who was one of the sons of King Pistachion.

He was voiced by Dee Bradley Baker, who also voiced Perry the Platyborg, Dr. Diminutive, the Spider-Monkey, and the Goozim. He is also voiced by Jeff Bennett, who also voiced Toucan Dan, Ace, Party Pete, and Baron Von Steamer.

Appearance[]

Derek is a large humanoid pistachio plant just Like the other members of his species. While he was disguised as a studio intern, he looked like a light skinned human with black thick-framed glasses short brown hair. His outfit consisted of a white collared short-sleeved shirt with a blue-grey tie and a pair of pants with visible seams and a black belt. His shoes were brown loafers with darker laces and white sock. He later wore a disguise to make himself appear identical to Orton Mahlson while the latter wore a Doctor Zone outfit but soon removed the mask, keeping the rest of the costume. After removing the gift box from his right hand, it is shown to be plantlike, while his left hand appeared to be that of a human.

Derek took off his mask for the first time in fifty years, dressing up as Orton Mahlson the entire time. As a result, his head is shaped exactly like Orton's, with a protruding chin and a bunch of brown cap-like leaves growing on top of his head.

Derek is now taller than the rest of the Pistachion, with a body similar to the King Pistachion in size and shape. He wears an identical outfit to Doctor Zone, but as a result of large stature, it is shredded at his legs.

Biography[]

Origins[]

Although Derek 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 Derek) to take over the world.

Missing Milo[]

In the hour-long special "Missing Milo", Derek appeared briefly when King Pistachion ordered him and several other Pistachions to capture Balthazar Cavendish, Vinnie Dakota, and Milo Murphy to prevent them from going back in time to destroy the sapling. However, the trio manage to escape in their time-travelling limo, but Derek has managed to catch up by holding onto the limo. As they travel through the time stream, Vinnie notices Derek and used a bag of clocks to knock him off the limo, leaving a helpless Derek to stumble around the time stream.

Following the deaths of King Pistachion and his other Pistactions in Milo's time, Derek ends in the year 1955. Smiling at this, Derek happily runs off as he intends to get revenge on the heroes for defeating his father and wiping out his race from existence.

Fungus Among Us[]

In the episode Fungus Among Us, it is revealed that Derek spend the next 10 years secretly plotting his own revenge against humankind for wiping out his race. Disguising himself as an intern for the Dr. Zone show in 1965, Derek uses the show's profit to formulate a successful plot that involves extinguishing the human race and replacing them with new Pistachions in disguise. He even was able to create his own army of Pistachions to diguise themselves as several of the show's crewmembers to help him out. This causes the time stream to change, allowing the Pistachions to round up the majority of the world's population.

With only Milo, Diogee, Dakota, Cavendish & Orton Mahlson remaining as the only ones to evade the Pistachions' capture, they seek to find the world's first time-traveler Professor Time to get some answers to stop Derek and the Pistachions from taking over the world. However, in the episode's cliffhanger ending, the five end up meeting the evil scientist Heinz Doofenshmirtz (who too has avoided being imprisoned by the Pistachions for unknown reasons) after being trapped in his lair by accident.

Phineas and Ferb Effect[]

It is later revealed that Derek himself spent the next 50 years expanding his race, which allowed enough Pistachions to take over the world. He is first seen under his Dr. Zone disguise where he confronted the main characters' friends about his successful takeover before revealing his true identity. He even raised the stakes by revealing his new plot to turn all humans into Pistachions with his newly developed machine called M.U.L.C.H.T.P. (Machine Used for Literally Converting Humans To Plants, though the last two letters are silent as Derek claimed) to take over the entire world, even using it to turn all of the main characters' families and friends into Pistachions.

Fortunately for the heroes, Doofenshmirtz was able to create a new time machine to gather up orange soda from 1965 that can easily destroy Pistachions just as his future self (revealed to be the actual Professor Time) arrives to bring Orton back to 1955. Witnessing this, a horrified Derek tries to stop Professor Time and Orton, but he is too late as they head back to 1955 and used the orange soda to destroy the 1955 Derek. With his past self destroyed, the future Derek can only watch in horror and fury as he starts to fade away from existence along with the other Pistachions. This restores the original timeline for good, turning everyone back to normal.
