In the Night Warriors OVA, Pyron comes to Earth just as the battle between Demitri and Morrigan begins. The Huitzil robots awaken to gather data on the Darkstalkers, Pyron's only real threat. There is no mention of him creating the robots. Evidence of this is that their programming is counter to his overall goals and they eventually having a falling out between them. Pyron is a powerful entity, capable of creating miniature suns (which also destroy large cities), which he uses especially to keep Demitri at bay. He also easily defeated Anakaris, Rikuo, Sasquatch, Victor, and Demitri in battle but it is not known if he fought Felicia, Lord Raptor, and Jon Talbain as well. He doesn't fight Morrigan as she was in the demon world during his descent to Earth.
