"Look, um when my dad was dying, he was barely coherent toward the end there, but he'd repeat this crazy mantra: 'If you see the handprint, go to Manes.'"
―Kyle to Master Sergeant Manes[src]

Kyle Manuel Valenti is one of the main characters on The CW science fiction series Roswell, New Mexico. He is the son of the town sheriff who learns about the horrible things his family has done in the past. Kyle is portrayed by Michael Trevino.

After discovering a mysterious luminescent handprint on Liz Ortecho's chest, Kyle seeks out Master Sergeant Jesse Manes, and from him learns the truth behind the 1947 UFO Crash. Upon discovery of Sergeant Manes' true intentions, Kyle began secretly helping Liz uncover the truth behind her sister, Rosa Ortecho's death, who Kyle would come to find out is his paternal half-sister with help from Alex.
