Mr. X (character)

"Do you know why they call me Mr. X, Jenny? Because I deal specifically with extraterrestrials and rumor has it that there are a few in the area."

Mr. X is a minor antagonist in Amphibia, serving as a major antagonist in Season 3.

He is a US government special agent from the FBI who with Jenny arrives to Los Angeles trying to capture the Plantars who are with Anne.

Personality
Mr. X is a flamboyant man that takes his job very seriously. He is suave yet casual, with traces of narcissism. Due to his specialty in dealing with the extraterrestrials, he also appears to be somewhat paranoid, instantly assuming the Plantars to be a threat in spite of lacking any actual evidence that suggests so.

Appearance
Mr. X is a tall bald man with black glasses and purple lipstick. He wears a dark purple suit with a light purple tie, a tan pocket square, and a yellow boutonnière. He also wears white pants, tan roller shoes, and a ring on his left hand.

Background
In "Anne-sterminator", the FBI detects that there are people frogs on Earth, and they call in Mr. X to investigate.

The enigmatic Mr. X and his associate Jenny have locked down on Anne Boonchuy and the Plantars. Convinced that they are aliens, the duo in their disguised ice cream truck plot to capture them for study. Mr. X and Jenny enter the Thai Go and inquire Mrs. Boonchuy about the appearance of alien suspects. She plays coy, but they immediately deduce where Anne and the Plantars are headed and leave for Super Cinema 40. Mrs. Boonchuy grabs her husband, and they race after them while trying to call Anne. Unfortunately, her phone is on vibrate, and she cannot hear it due to the loud movie. Upon exiting, Anne is too late to learn that Mr. X has arrived and gives chase throughout the theater. Mr. and Mrs. Boonchuy continue to call Anne to try and offer their idea on how to rescue her and the Plantars, but she continues to avoid them and turn down their help; believing she can do it on her own.

Anne and the Plantars find themselves holed up in the restroom as Mr. X calls a SWAT team for backup. Nevertheless, Mr. and Mrs. Boonchuy decide to go forward with their plan. They knock out the lights, pull Anne and the Plantars through the vent and leave behind two regular frogs and tadpole; humiliating Mr. X who is instead impressed with the challenge and vows to capture them.
