Fertile Seed is a unicorn who has the uncanny ability to make mares horny for him, and in turn knocking them up with a complete success rate. His cutie mark is that of a happy seed that smiles. When he was young and got his first erection was the same day as he knocked up his first mare. Since then he has been travelling all across Equestria visiting many places and leaving many pregnant bellies behind on the way. He hates wearing condoms. He take great pride and enjoyment in being the father of so many foals. After seeing a flier for an airshow featuring two independant pegasus ponies doing stunts and tricks. It happens to be their last show for the season, so, he decides to take the opportunity to knock both of them up while he has the chance.
