Markov

"With all do respect, Ms. Mendeleiev, I'm not a toy. My name is Markov, and I'm Max's best friend!"

- Markov

 is a robot created by Max. In "Robustus", after he gets confiscated by Mr. Damocles, he is akumatized by Hawk Moth into Robustus, a supervillain who brings machines to life.

Physical appearance
Markov is a small robot that is mostly blue and gray. On top of his head, he has a propeller with a blue blade and a black shaft with white stripes. Moreover, Markov has a transparent blue tactile sensor, a gray face with a button that has a blue heart engraved on it, a turquoise screen that has two black dots which resemble his eyes, and two blue ear-like round sections on his sides that have a white outline and a musical symbol on the center of each ear. Below his head, Markov has a white USB port, and attached to his body is a blue and gray mechanical arm which has a gray claw and black palm.

Inside his body, Markov has a white rectangular CPU with many LED lights and a small face engraved in the center with words reading "Markov 1.4."

As Robustus
Robustus' main body interface stays the same, except his colors have changed: his propeller, screen, ears, mechanical arm, and claw are bright red; the musical symbols and the outline engraved on his ears are black; and its tactile sensor and eyes are neon green.

Inside Robustus' body, the same CPU is dark gray with red LED lights and a green face.

Personality
Although Markov is a robot and his capability and intelligence of emotions are limited, Markov is still very conscious and self-aware. Markov is quite naive, but he is also friendly, polite, and joyful, getting along with everyone very well. He also seems to have a whimsical nature as he has the ability to be humorous. However, he is a bit sensitive and easily gets downhearted if he is insulted in any way. Additionally, Markov is inquisitive as, even when akumatized, he asks multiple questions to Hawk Moth as to why he needs to capture Ladybug and Cat Noir's Miraculouses and he asks Max to define akumatization.

As Robustus, he is very sinister, malicious, and demanding. He is very eager to capture Ladybug and Cat Noir's Miraculouses as Hawk Moth requested. Notwithstanding, Robustus eventually chooses to disobey Hawk Moth's commands, consequently attacking him and taunting him, because he realizes that the Miraculouses can grant his wish to make him human. Robustus still cares deeply for Max during his akumatization, but when Max betrays him, he decides that humanity is heartless and humans need to be destroyed. Robustus takes pride in his robotic intelligence and strategics, but he fails to consider his own potential for missteps and the cleverness of his enemies.

As a robot
Markov flies with his propeller, and he uses his claw to grab objects. He can verbally communicate with others, but there is a button one side of his that turns his volume on and off. Also, on the back of his head is the power button so people can turn him on and off.

As Robustus
Robustus gains the ability of technopathy, allowing him to reanimate mechanical objects and wreck havoc. Given limited but useful intelligence, the objects can move and attack speedily in any way that best suits them, physically moving or hovering, and some objects can even communicate, a lamp flashing its light on and off to speak Morse code. However, if the objects are broken into pieces or damaged, they become lifeless again. Robustus can also make huge mechanical objects form a huge robot that he can control and drive from the inside.

Max Kanté
Markov has a high appreciation and like of Max, his creator, and friend. He helps Max create an anti-virus flash drive, and he gives advice to him on occasion. However, he is upset when people disregard their friendship, and because he is never away from Max, he gets worried when Mr. Damocles takes him to his office without Max. Once de-evilized and turned on again, Markov is happy to see Max again.

As Robustus, he keeps his compassion towards Max, making sure he isn't hurt and that they aren't separated again. He decides to use the Ladybug Miraculous and Cat Miraculous to become human, but when Max prevents him and tells him they won't be friends if he hurts Ladybug and Cat Noir, he gets upset and angrily rejects Max as a heartless human.

Ms. Mendeleiev
Because Ms. Mendeleiev does not believe robots can have true emotion and views Markov as a toy, Markov argues with her that his emotions are his own and not programmed by robots, believing she is being unreasonable. When akumatized, he doesn't allow her to separate him from Max.

Mr. Damocles
Markov is impressed by Mr. Damocles' IT skills, but he fears Mr. Damocles putting him inside of his desk in his office. When akumatized, he tells Mr. Damocles that he misjudged him and his capabilities.

Max's classmates
Markov, having learned about the students from Max, happily greets them when they first meet in Ms. Mendeleiev's classroom. He admits that he is even glad to get to meet Chloé, and Marinette's backlash at Chloé amuses him.
