Other Roswell Characters
Diane and Phillip Evans-Adoptive parents of Max and Isabel Evans. Not much is known about either. Phillip is a lawyer. Diane seems to be the parent that's closest to Max and Izzy, though neither of them knows the truth about their children.

Jeff and Nancy Parker are the parents of Liz Parker. They own the Crashdown Cafe. They are played by John Doe and Jo Anderson.
Kathleen Topolsky showed up at Roswell High as a substitute geometry teacher and guidance counselor. The group later learned that she was an FBI agent sent to learn the truth about Max, Michael and Isabel. She left town after discovery, only to return months later to warn the teens about the danger they were in from the FBI special unit (the alien hunters). She was abducted and assumedly killed by Agent Pierce of said special unit.
Picture: Topolsky from the episode "285 South." Agent Topolsky was played by the very talented Julie Benz, who ironically enough, also plays the vampire Darla on "Buffy the Vampire Slayer" and "Angel."
Nasedo is the shape-shifting alien that Max, Michael and Isabel searched for during their sophomore year of high school. Nasedo has killed many humans to avoid getting caught. He kept Tess with him until he finally caught back up with the other three aliens.
Riverdog is the Native American that has helped the teens on a couple different occasions. He first met Nasedo when he was just a boy, and helped save the alien's life, and then later, helped save Michael's when Michael got ill during a Native American ritual called the Sacred Sweat Ceremony. He's one of the only humans to know the secret.
Picture: Riverdog from the episode, "The Balance." Riverdog is played by the talented Ned Romero.
