The invasion, is it the end?

In a separate galaxy far, far away, an evil deranged being named Satsujin and wife Itazura are constantly destroying multiple different forms of life to expand upon their own race, Mozarians. Mozarians are an endangered species of reptile-like aliens that use advanced technology to terrorize universes. Mozarians have superhuman strength, speed, durability and mental capacity. However, Satsujin and Itazura are not always successful, as a specific kind of genetic enhancement was able to repel them. This enhancement is called "The Blessed Child Gene". This can counteract a Mozarian's power, as the gene can increase strength, durability, speed, reflexes, agility and even intelligence. This gene received its name because of it's rarity, being able to skip generations in families, start in families randomly, and act as if a complete reincarnation. If two beings with the blessed child gene were to cross, the gene with instantly be passed. The rare gene can be brought into many different kinds of species, except Mozarians.
