Jason Burr was the twin brother of Jeffrey Burr, also known as the super-villain Kobra. They share a psychic link that makes both brothers feel any pain the other is experiencing. Kobra considered Jason to be his greatest vulnerability, but could not despose of Jason without harming himself. Jason hated his brother and dedicated his life to destroying him. Following Jeffrey's death, Jason took over as the new Kobra and became leader of the Kobra Cult.
