Riot was one of the four Symbiotes that was transported inside a comet from their planet to Earth. While the first three Symbiotes were captured by Carlton Drake and his men to perform illegal experiments on human hosts, Riot was the only one to escape, landing in Malaysia. For six months, Riot made all his way from Malaysia to the U.S. by hopping from one host body to another. Taking a little girl as its current host, Riot made his way to Life Foundation HQ, where he learns of Drake's intent.
