MOVIE #2
An alien male comes to Earth and impregnants a woman. Their alien/human hybrid son eventually develops pyrokinetic abilities, and that’s when an evil alien bounty hunter in human form comes to Earth to capture/kill this hybrid.
I saw this movie in 2001, but it was shot in the late '80s-early '90s. The cover of the VHS had some naked ripped guy standing waist-deep in water, his arms outstretched to a flying saucer hovering overhead.
Sounds a lot like Abraxas: Guardian of the Universe, which I know from We Hate Movies and RiffTrax.
