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.

After receiving his M.O. Operation Ivan gained the powers and abilities of the plant Datura Stramonium, that make him able to cause fever, hallucinations, breathing disfunction, and even heart failure to his opponent when hit.
