Captain Kirill is the Russian captain of the icebreaker NS Yamal. He knows better than to poke too far into things.
During a mission to deliver families to McMurdo Station, Kirill complained about Pavel slurping his coffee. A few moments later he had bigger worries, as Megatron ripped the roof off the ship's bridge and announced he was commandeering the ship. Kirill managed to stammer out a surprised exclamation before Starscream used a static lance to knock the entire crew out. When Kirill recovered, the ship was already at McMurdo. While Pavel wondered how they'd write up the incident, Kirill told him to go find some proper American coffee instead.
