Ramirez was the captain in charge of HazMat Team Bravo he seemed like he was always focused on the mission. He seems to be a strict militay man but this is contradicted by Cole, who states he respects his team and their duty. He dislikes Crispy's jokes dismissing them as smartass remarks.Ramirez died when him and Crispy encounterd the Theta. While Crispy was hit and infected by the Theta, Ramirez was thrown at a fire door which the force breached his suit which caused it to implode killing him instantly.
