Oliver Riggs

The son of Charles Riggs, a security guard at the U.N. His mother, Bowie O'Shea, was a musician who left after Oliver was born. Oliver was the outcast at Nobel High, being a 'loser skater'. When Luna came to their school, Oliver develops a crush on her. He knows that Luna likes Jonah very much, but he does not accept it. He does not notice that Francesca has or had a crush on him. He later finds out Luna's identity when they are being attacked by a clone of Elizabeth Westbrook.

Later, it is discovered that Oliver's father is working with Count Von Brucken, and he gets arrested. Oliver then lives with his mother, who is pretty easygoing despite their distant relationship, but does try to take care of him. But when Oliver discovers that Luna's agency is forcing Brucken to work for them, he gets angry at Luna for letting Brucken live in their house, while Oliver's father is still in jail. His relationship with Luna becomes strained, but he nonetheless keeps her secret.

Oliver soon becomes good friends with Heather, one of Elizabeth's lackeys. Heather warms up to Oliver's kindness, and becomes sick of Elizabeth's bossiness. Oliver hangs with Heather while he is still upset with Luna, but still doesn't confirm that Heather is actually his girlfriend. He eventually reconciles with Luna, and he, Luna, and Francesca reaffirm their friendship with each other.
