"Who are you"

The Bloon Solver is completely encased in a heavy-duty, lime green hazmat suit designed to protect themselves from its own lethal chemicals. Its face is hidden behind a specialized gas mask with dark lenses, a design choice that carries over from the Bloon Liquefier to emphasize its role as a hazardous materials specialist. To store its extremely corrosive acid, she carries a massive, metallic-coated chemical tank on its back, which is connected to a high-tech glue gun by thick, glowing green tubing.

She is depicted in a menacing stance, surrounded by a thick toxic green vapor that matches the glowing green windows on the side of its weapon's nozzle. This ensemble creates the image of a specialized scientist who has traded traditional glue for a substance powerful enough to dissolve almost any Bloon in seconds.
