Robot Milo is a supporting antagonist of the Milo Murphy's Law episode "Abducting Murphy's Law". He is an organic android created by the Octalians to pose as Milo Murphy during the latter's kidnapping by the Octalians.
Just like his original counterpart, he was voiced by Weird "Al" Yankovic.
Having previously gained Milo's DNA, the Octalian Commander kidnaps Milo while getting her fellow Octalians to create a new android to take his place so that no one would find out. Unlike the original Milo, Robot Milo acts very sarcastic and rude towards Milo's friends Zack Underwood and Melissa Chase, even calling Heinz Doofenshmirtz a loser many times, much to the latter's annoyance.
However, it was not the case when Murphy's Law caused one of Doof's inators to fall through Milo's bedroom, causing Robot Milo's head to fall off. Realizing that Milo is in trouble, Zack and Melissa interrogate Robot Milo about the whereabouts of the real Milo, to which the android explained that the real Milo is captured by the Octalians.
Doofenshmirtz then created a new inator called the Shenaniganator that is designed to track down negative probability ions. He soon learns that Robot Milo's head still has Milo's DNA and attached it to the inator to properly locate Milo, who has fallen from the Octalian ship after a series of mishaps. Doofenshmirtz then blows several balloons for Zack and Melissa to safely capture Milo, but Robot Milo stated that the Octalians will be returning sooner or later.
