Robert Otto

Robert Otto is a minor antagonist and character in Amphibia. He was the community safety officer in a local area within Los Angeles, California, but when his position was overshadowed by the Sprig's Frog-Man persona, he briefly became a super villain to reclaim his title.

Personality
Robert is a very self-centered character and determined when it comes to his goals, like destroying Frog-Man or his job being the neighborhood security supervisor. He also proves to be quite jealous, especially after seeing everyone worship Frog-Man and ignoring the fact that he "slowed down the bus". Despite his ardent demeanor, Robert cares greatly for his granddaughter and her well-being. He is reasonable, acknowledging that his and Sprig's desire for recognition was reckless, and resolved to help clean up the damaged streets to make up for the destruction they made. He also conceded to a police officer arresting him as punishment for the fighting.

Body
Robert is a tall, elderly man who has light-brown scruffy hair and visible wrinkles around his eyes.

Clothing
While helping the neighborhood, he wears a yellow visor with a black helmet and knee pads on his arms and knees. He wears a white blouse with a brown vest and light black jeans with a belt and rollerblades. He also wears a green bag with a long shoulder strap that he uses as a money belt.

After he returns with the objective of eliminating Frog-Man, in addition to using Cloak-Bot's right arm as a weapon on his right arm, he now also wears glasses with a yellow visor and a brown suit with a green scarf.

Background
Sprig encounters Robert, who claims to be the neighborhood's 'protector', though the kids find him a nuisance. Suddenly, a runaway school bus careens down a hill, and both Sprig and Robert hop into action to stop it. Robert fails to do anything helpful, but Sprig manages to stop the bus with his tongue into a net; pleasing the nearby citizens as well as Molly Jo, Robert's granddaughter, who was one of the passengers on the bus. Sprig continues to help people all over the city and hits the news, which Anne and Polly angrily see. A jealous Robert later finds Cloak-Bot's right arm at his junkyard. Impressed with its abilities, he decides to use it to get revenge on "Frog-Man".

While receiving adoration, Sprig is attacked by the newly powered Robert, and they proceed to wreak havoc across the streets of Los Angeles. After saving Molly Jo from harm's way, she chastises the two of them for causing so much damage. Realizing that he was in it for the fame, Sprig and Robert use their abilities to clean up the town. Sprig then tells her that he is happy that she talked some sense into them and leaves, though Robert is told by a police officer he will most likely get arrested due to the damage he caused, which he accepts his fate as fair.

Abilities
As a human, Robert doesn't have special abilities, but with Cloak Bot's arm, he gained all of its capabilities.
 * Strength: Robert's strength is enhanced to superhuman levels with the arm, which allowed him to lift vehicles with ease, break large objects with claws and punches, and the entire neighborhood, all without burdening himself due to the arm's lightweight material.
 * Extension: Robert can extend or retract as far as necessary, and used this to swing himself across great distances.

Name and basis
Robert's last name, Otto, and the fact that he uses a mechanical arm whilst in his supervillain persona bears some similarities to the Marvel supervillain Otto Octavius, better known as Doctor Octopus. While Robert's first name could be a reference to Brad Garrett's character Robert Barone on Everyone Loves Raymond.

Voice
Robert is voiced by Brad Garrett. Garrett was announced as a guest star in the third season on July 24, 2021.

Debut
Robert debuted in "Spider-Sprig".
