Max as he appeared when normal
Max is a vampire and one of the antagonist in the movie The Lost Boys. Throughout the movie, he can hide his vampiric characteristics and fool the protagonists into thinking he's normal.
Max met the protagonists when Lucy started working in his video shop. They dated and Lucy invited him over for dinner. The only people who suspected him as a vampire are the Frog Brothers, and during the night, they ran a series of tests to see if he really is a vampire.
In the tests, the brothers tried to see if he has a reflection, and he did, much to the Frog Brothers' expectations. They try using garlic, but it, too, failed. In the end, the brothers were convinced and Max is finally welcomed to the house, giving him invitation to go inside anytime he wanted.
In the end scene, he proclaims to Lucy that all he wanted was for her to be a "mother" for his "lost boys" and inviting vampires renders them powerless.
Max in his true form
He shows his true form and attacks everyone excepts Lucy, then attempts to turn her, but Grandpa crashed his jeep and impaled Max on wooden fence posts he is carrying, forcing him into the fireplace and blowing him up.
