Kostya Yesenofsky

A figure from the shadowy corners of Marvel's late-'90s Venom universe, Kostya Yesenofsky made his debut in the 1997 limited series Venom: License to Kill, brought to life by Larry Hama and Derec Aucoin. Sharing the page with Venom himself alongside the likes of Sergei Yesenofsky, Doctor Yes, and Red Flag, Kostya moves in genuinely dangerous company. With only a handful of appearances to his name, he's a rare, specific piece of that gritty Modern Age corner of Marvel history — exactly the kind of character that rewards the deep-diving collector.
