As the Infinity Stones are too dangerous to be used by themselves, Dr. Light suggested Tony Stark to create a device to harness their power. In Sigma's laboratory, Tony and Thanos created the Infinity Buster to harness the power of four Infinity Stones and gave them to X. When used, it fired a powerful beam capable of destroying Ultron Sigma.
