Cloak-Bot

"Target... will be destroyed... at all costs."

The Cloak-Bot is a minor antagonist in Amphibia, serving as a major antagonist in Season 3.

It was a stealth class Frobot sent by King Andrias from Amphibia to Earth to hunt down and eliminate Anne.

Appearance
This Frobot had a silver and grayish green paint job, was lanky and thin to quickly maneuver in urban areas, had 8 razor-sharp claws attached to 2 long arms, and has 3 toes on each leg. It had a horn that curves backward at the top of its head, and its optics were red. It had tubes on the sides of its torso, two of which were attached next to what seems like a blue light on its left, and had two large darker-colored shoulder pads. The robot was equipped with powerful, long legs and was quite tall, as it even towered over human adults.

After being repeatedly damaged by Anne and the Plantars, the Cloak-bot replaced its broken parts with construction equipment and other things. It had put metal plates on the left side of its face, its left eye was cracked, and there was a tire where its right shoulder plate used to be. As of result of its left arm having been cut off, the robot replaced it with the claw from an excavator. The robot also replaced its right leg with a buzz saw and gave itself a nail gun attachment on its back.

Personality
Like Frobo, the robot showed some form of intelligence, as it could be seen laughing or making sassy remarks at its foes. However, its intelligence had limits, as shown when it had trouble understanding King Andrias' command to get potato chips. Unlike Frobo however, the robot was programmed to be very merciless and even somewhat sadistic. The Cloak-Bot was also highly murderous, as it was willing to kill anyone who stood in its way of killing Anne and the Plantars (including Mr and Mrs. Boonchuy). It was very loyal to King Andrias and was willing to sacrifice itself to accomplish his goals and the destruction of all of their enemies.

Background
King Andrias sent it to Earth mainly to find Anne and kill her, but also to get him a Cynthia Coven book. When it arrived at Earth, it easily managed to locate its target by using its sensors to scan the area of her energy signature, which was attained from the Calamity Box. At the supermarket when in stealth mode, the Frobot used its stealth mode to scout the market and attack Anne and the Plantars, but they fought back discreetly to avoid unwanted attention. Eventually, Anne unleashed her blue gem energy when she saw the Plantars in danger and heavily damaged the left section of the killer machine with her left fist. It fled with its camouflage system flickering on and off. Afterwards, the Frobot was seen atop a tower on a stormy night while making repairs to its body, deciding to redouble its efforts to terminate Anne at any cost.

In "Fight at the Museum", the robot continued its hunt for Anne and eventually managed to locate her at the museum when it sees Sprig through the museum's cameras. The robot went through the building's roof and immediately engaged in combat with Anne and the Plantars. After having its left arm cut off by Hop Pop dropping a guillotine, and having a massive animal skeleton dropped on top of it, the robot is seen by the museum's curator, Dr. Jan, and the security guards. When it realised that it had been exposed by human adults, the robot quickly fled the scene. In "Temple Frogs", the robot sent in dragonfly-like UAV drones to try and kill Anne, but was thwarted when Anne, the Plantars and the Thai American community fought back. In both incidents, the robot failed to keep itself and its reinforcements hidden, but was indirectly helped by Dr. Jan and Anne when they told the people it was either part of a performance or because of Anne's SJMS schoolmates.

Back in the tower, in "Anne-sterminator", having forced to replace his lost body parts with construction equipment, the robot receives a call from Andrias. Not only did it got the wrong Cynthia Coven book due to Book 2 being sold out, Andrias is very unhappy about his failure to kill Anne, and sets a self destruction bomb in his body to detonate if it fails his mission under an hour. Luckily, due to an unidentified Frobot, the robot easily manages to track Anne at her house. The robot manages to find Anne, her parents, and the Plantars as they escape from it. The robot navigates to one room and gets fooled by the fake Anne statues placed in it. After beating up one of the statues until it was exposed, the robot sees Anne in the driving van, prompting it to chase it as it attacks Anne and the Plantars with various deadly tactics. After being flattened by the van with little time left, the robot manages to find it in the junkyard just before Anne, her parents, and the Plantars hide. Later, the robot gets fooled by more fake Anne statues as it shoots them down just as Anne, her parents, and the Plantars attack and severely damage it. Just as they are relieved, the damaged robot proceeds to self-destruct to kill all of them in ten seconds just before Anne uses her Calamity powers and right foot to forcefully kick it into the atmosphere as his bomb explodes, destroying it for good.

In "Spider-Sprig" the right arm of the Cloak-Bot is found by the junkyard owner Robert Otto who, jealous of Sprig who had decided to become the superhero Frog-Man, uses it on his right arm to become a 'hero' to destroy Sprig till he stopped this madness once his granddaughter Molly Jo told both him and Sprig that they caused so much damage in LA, which both of them quickly fixed stuff up. While Robert would be arrested by a cop from the LAPD for the damage he did, what happened to the arm is still unknown.

Powers and abilities

 * Strength: The Cloak-Bot uses its claws and arms numerous times to break or damage objects and has been shown to have a lot of strength to the point where Anne and the Plantars have had to either tap into Anne's Calamity Powers or use any object they could find to defeat it.
 * Location sensors: It has specialized sensor technology to locate where Anne is by matching her energy signature with the blue gem of the Calamity Box. Though the sensor seemed to be non-functional after it was damaged by Anne as seen in "The New Normal".
 * Stealth mode: It can hide from view on Earth by its active camouflage system while walking during daylight without getting seen, but its camouflage can be deactivated by magnets and whenever it is hit by various objects. Even in camouflage, the Frobot crushed a lot of cars, can be seen with other items on it, and even the automatic sliding door at the 99 Ranchers store can detect the Frobot even when the camouflage system is on.
 * Flexibility: It is quite flexible, as it can squeeze into small areas to hide from view whenever it can't use its invisibility cloak.
 * Agility: The robot is also shown to be very agile, being able to move very quickly despite its tall stature and long arms.
 * Multi-purpose claws: Its left claw can be converted into a plasma weapon for range attacks. It can repair itself with its claws, which act as blowtorches. The claws can also function as drills, change into a satellite dish or an axe.
 * Lasers: The Cloak-Bot can shoot extremely lethal highly concentrated laser beams from both its optics.
 * Hacking: As demonstrated in "Fight at the Museum", Cloak-Bot can hack into electronics to look for its target. Furthermore, in "Temple Frogs", it could intercept radio and wireless phone signals.
 * Drone deployment: It can unleash dragonfly-shaped UAV drones to scout and hunt targets.
 * Body Part Substitution: The Cloak-Bot was able to replace various broken parts of its body, with scrap and parts of other machines like a tire for its right shoulder plate.
 * Nail Gun: As a part of Cloak-Bot's repairing process in "Anne-sterminator", a nail gun was added to Cloak-Bot's weaponry, specifically located on its back and is attached by Cloak-Bot's right leg which has been repurposed as a turret base, and it uses it later in the episode.
 * Excavator's Arm: As a part of Cloak-Bot's repairing process in "Anne-sterminator", it replaced its missing left arm with an excavator, which is less versatile than its old arm but more durable, and is used to grab and crush things, or deflect projectiles.
 * Disk Saw foot: As a part of Cloak-Bot's repairing process in "Anne-sterminator", it replaced its right foot and leg with a disc saw, that can be used to attack and cut or as a wheel that allows it to move fast enough to chase a car.
 * Self-destruction: The Cloak-Bot was built with a self-destruct device that could be remotely activated by Andrias should it fail in its mission. The function came with a one-hour time limit, after which it would detonate into a large explosion, enough to level at least half the city. When Andrias was disappointed with the Cloak-Bot's failure to terminate Anne, he activated the timer which forced it to take care of Anne within that timer, though still failed.

Early development
The Cloak-Bot began as a conceptual sketch of the Frobot variants that character designer Joe Sparrow drew for "True Colors", and ultimately did not make it to the final version of the episode. This design was later used for the character in season 3.

Voice
The Cloak-Bot is voiced by Troy Baker, who also voices Captain Grime.
