Ivan Perepelkin is a Russian boy under Sylvester Asimov's tutelage who joined the Annex Project along his sister, Elena, to find a cure for the deadly A.E. virus that afflicts the Earth. He is introduced as an honest, albeit gullible, individual. He developed a crush on Sheila Levitt after she treated his wounds when he took a punch meant for Jet.
