Yoko konzentriert sich wieder auf ihre Gesangskarriere und tritt in verschiedenen Shows und bei Wettbewerben auf. Eine geltungssüchtige Aliendame, die ihre Form beliebig verändern kann, entdeckt Yoko bei einer Show und beschließt, ihr Äußeres anzunehmen und als ihre Doppelgängerin Karriere zu machen. Brett und Josh sind anfangs verwundert über Yokos eigenartiges Verhalten und offensichtliche Gedächtnislücken. Mittels seines Arm-Computers stellt Brett dann fest, dass es sich nicht um Yoko handelt …
When Yoko gets a singing gig at an intergalactic concert hall, she’s totally psyched. And when she plays to an enthusiastic, sold-out crowd, she finally feels like she’s on the path to becoming famous! When she returns to Galaxy High, she finds herself showered with flowers, gifts and poems – all sent to her courtesy of the Yoko Maniacs – her official Fan Club. And when she gets an invitation to appear at an upcoming fan club meeting, she can’t resist! When she arrives at the meeting, however, Yoko is confused to find only a single alien fan there. What she quickly realizes is that the alien, who has the ability to shape-shift, has lured her there with the intention of capturing her and taking over not just her appearance, but also her new career! Meanwhile, back at GH, the gang gets an urgent call from Principal Kirkpatrick, sending them on an emergency mission. When Josh and Brett realize that Yoko is missing, they set out to find her – before tackling their assignment. And when they fly past an outer-space billboard advertising her latest gig, it doesn’t take them long to do so. When they arrive at the venue and approach Yoko, however, they immediately start to sense something strange about her. Regardless, they convince her to go with them. But when Josh and Brett see that Yoko clearly can’t handle her marshal duties, their suspicions grow. And when a distrustful Fluffy reveals her to be an alien imposter, she captures them just like she did the real Yoko… and sequesters them on her home planet with their missing teammate (where they’re all left in a threatening predicament)! The gang ultimately escapes the alien’s planet and tracks it down – defeating it in a battle that prevents it from doing any more damage to them or Yoko’s career. In a b-story, Yoko gets a lucky charm which she’s convinced is going to help her become more successful.
