In Marvel Comics, Sidewinder started as an economics professor before becoming a criminal for hire after gaining the ability to teleport. He later forms the Serpent Society as a powerful criminal organization. He is incredibly frustrating for Captain America ashe uses his teleportation abilities to commit crimes and free his many followers from prison. While his role in the comics might be small, he could have a massive impact on the future of the MCU.
