Josie

History
Josie is one of Johnny's two friends from Earth, and she is a responsible, intelligent and mature girl who finds herself to be a much more important element in Chronos near the end of the second season of the TV series.

In addition of episodes where Johnny hangs out with his Earth friends, Josie is also in other episodes where she helps out the Warriors with her incredible skills in computers. In episodes "The Futurus Disaster" and "Josie and Ruby", Josie helps Sergeant Cyborg with computer problems, showing that she is very fluent in computer programming and advanced technology.

Josie also has a pet dragon since the episode "Josie and Ruby", where she decides to keep a baby dragon she finds in Chronos; she names her Ruby, because of the stone the dragon has around its neck, which is revealed to be the Dragonstone. Josie then brings a dragon and one of the Four Relics of Chronos to Earth until "Runaway Dragon", when she sees how much trouble it can cause to Earth, and she trusts Johnny and the Warriors of Chronos with taking care of her pet dragon.

In the second season of the TV series, Josie meets the Pixies and discovers that she might not be really good at regular magic, but that she is a natural in Pixie Magic. After seeing what she can do in "The Pixie Witch", Josie decides to stay in Chronos as Princess of the Pixies, and become a Warrior of Chronos as ambassador for the Pixies. Josie becomes the Pixie Witch and is reunited with her pet dragon Ruby. Her role as Pixie Witch wasn't explored in the last five episodes of the second season that came after, but she was featured in both TV movies that followed the series' finale, and she was supposed to star in her own spin-off series, which ended up as a two-part pilot that was never picked for a continuation.
