Poxy

Poxy (voiced by Frank Welker) is Experiment 222 of Dr. Jumba's Experiments. He is designed to enter the bodies of and infect popular planetary leaders; the symptoms are purple pimples, smelly feet, swollen eyes, and uncontrollable burping. The symptoms continue as long as Poxy is within the victim's body, and vanish almost immediately when he is not. He was captured by Gantu, but was rescued in "Snafu".

According to a bonus feature game in Lilo & Stitch 2: Stitch Has a Glitch, his one true place is fixing health problems.

Appearance
Poxy is an incredibly tiny, pale green-grey, single-celled experiment with a white inner body, black eyes, a round nose, a wide mouth, pink-purple spots and four grey-tipped antennae.

Primary Function
Poxy acts like a virus. Once he has found a host, he inflames the periorbital edema of the eyes. The pores around the victim's body get infected, after which small amounts of blood get trapped in them, giving them a purple color. The sweat glands in the victim's feet overwork, giving them a nasty stench. Nitrogen and other gases are released almost instantly through the victim's stomach; hence, uncontrollable burping. Poxy can split his body and bend it around with no effort, implying that he may be a single-celled organism. Poxy seems to stay off the antibiotics radar, as they pay no attention to him whatsoever. This may be because they don't see him as a threat, he appears as part of them, he has taken control of them, or Jumba simply made him immune to them. Poxy has no need to breathe without air. He may presumably have a form of gills, or it is also possible that he filters the oxygen from blood.==Weakness== Poxy can become easily stuck in earwax.

Trivia

 * In "Poxy", Poxy was microscopic size. However, in "Snafu", he was the standard size of an experiment. This might imply that Poxy can change size while using his function as a germ, but it is possible that his container acted like a lens and magnified him to a noticeable size, as he disappeared when he was released.
