Gamer

Gamer (voiced by Ben Diskin) is a  supervillain who controls a huge fighting robot. Gamer's skin is purple and his eyes are red. His glasses become butterfly-shaped, and the glass has a light green tint. He wears a black full-body suit with a small green circle on his chest and three thin green stripes around his waist, each forearm and each lower leg. As a villain, he stops at nothing to show everyone that he's the best gamer, even turning people into experience points that help him level up. Additionally, the resentment he held towards Marinette turns into hate, resulting in him specifically targeting her for a brief period.

Powers and Abilities
As soon as he transforms into Gamer, he gets a giant fighting robot designed after MX-01 from Ultimate Mecha Strike III. He starts off with the robot's Level 1 form, a simple floating black pyramid with a green eye, but by shooting at the population and cars, he turns them into experience points that make him level up. Level 2 adds two tall tentacle-like legs. Level 3 makes the robot more human-like and gives it the power to perform some special moves, like firing electricity and missiles, creating a force field and spinning to make a drill. Level 4 is the final level, but its form is unknown.

With his glasses, Gamer is able to save his last level and respawn in case his robot is destroyed.
