Alexis Lorenzo

Alexis Lorenzo comes from a poor family. After watching his father die from a sniper's bullet he has since vowed to help destroy evil. He became a policeman and tried to live up to the principles of righteousness even when his colleagues were being corrupted by criminal elements. When Gallian finds him he joins the Galactic Force and eventually becomes the Green Zaido. He has feelings for Amy but has not yet realized this. His name, Alexis, is the same as the main character in the Philippine dubbed version of Shaider. Alexis turns out to be Drigo's son, which Helen had said to him, and half-human half-Kuuma. He is part of Kuuma forces due to his father, Drigo, and he is renamed as "Sigma" by Le-ar. As Sigma he commands the revived Kuuma monsters to bring forth chaos on Planet Earth. Despite being a Kuuma he does not kill his mother. Alexis, along his brother Alvaro, witness the death of their mother who was killed by Le-ar. Before the final battle between Le-ar and the Zaido, Alexis returns as Zaido Green after he forgives Gallian and his friends. When he transforms he utters the words: Codename: Zaido Green: Sugo ng Kabutihan (Disciple of Goodness). In the end he tells his cousin Thor that he needs to resign as an officer so that he may work in Galactic Force but instead he chooses to stay on Planet Earth and finally lives with his brothers and Mona.
