Riley
Riley was a newborn vampire, created by Victoria to act as the leader of her recently formed newborn army. He accompanied her in her attempt to murder Bella Swan, and was killed by Seth Clearwater.
Riley was among the first humans, if not the first, that Victoria changed into a vampire so as to form her army. She needed an older vampire to help control the newborns. To get him to work with her, Victoria told him that she loved him and convinced him to serve her faithfully. He corralled the other new vampires and told them what their mission was and what they were supposed to do.
Riley was also the one who came into Bella's room to get her scent. This was because he was the only mature vampire there besides Victoria. If any newborns had come there, Charlie would have been killed. Thankfully, Riley spared him.
When he faced Edward in the clearing, Edward tried to convince him to give up the fight by telling him how Victoria really felt about him (she didn't really love him; her mate was James who was killed in Twilight), but Victoria’s hold on him was too strong. He tried to attack Edward, but Seth got to him first. Seth, with unnecessary interference from Bella, manages to defeat and kill Riley.
Riley changed many humans for Victoria, instead of Victoria doing it herself, so that when the newborns first thought about who changed them, they wouldn't think of Victoria. So, Edward Cullen wouldn't be able to read their minds and see Victoria coming. Riley remained a tool of Victoria's until death.
Riley died because he made the foolish mistake of being loyal to Victoria, when really she didn't love him at all (which Edward tried to tell Riley) and was only using him to kill Bella.
Riley is described as being around Bella's age when he was changed, with vivid red eyes and shining blond hair. He was muscular and tall, and used his newfound vampire strength with little tact, like most newborns. He fell in love with Victoria, but she lied to him and he died fighting alongside her.
After Victoria changed him, Riley became nothing more than a menace just like the sadistically dangerous and psychotic vampire, Victoria, until they both died attempting to kill Bella.

"She knows that I will kill you, Riley. She wants you to die so that she doesn't have to keep up the pretense anymore. Yes - you've seen that, haven't you? You've read the reluctance in her eyes, suspected a false note in her promises. You were right. She's never wanted you. Every kiss, every touch was a lie."
