Silvester Asimov is among the strongest officers of the Annex I Mars mission. He is in command of the Russian team which includes some of the most talented fighters. He possesses the power of the Tasmanian king crab. He uses a drug in the form of a cigarette for his transformation. Asimov is a former military man from a small country that is part of the former Soviet Union (USSR). His motive for having to undergo the medical operation and to take part in the mission is to found a cure for his pregnant daughter. His son-in-law is also in his team. The interesting thing about Asimov is that he is strong enough to kill a humanoid Mars cockroach even without using his special power.
