the xengley family are a family of five. Two human parents, and three alien sons, Greg xengley, who is a xenomorph alien. As Rodrick xengley is a predator alien.. And manny, the youngest. Manny xengley is a n alien hybrid, specifically a combination of human and Tetramand, so its a bizarre family really.. But it seems like no one you know seems to have a problem with it! As the parents Susan xengley and Frank xengley. And they're the only people in this world to have sons that are aliens.

but There is one person that was never seen, but was mentioned once or twice, but was mentioned by Rodrick before. Which was you. sO who were you in this?
