This and the following episode’s basis, like with most Team Planetary episodes, come straight from a part in Luna, Terra, and Sol. In the original version, you find that your way is blocked by the Bicycle Road on Route 7, and you have yet to get a bike, leaving the only way you can head as being up Route 16, towards the Starstreak Mountains. One up their, you’ll find Professor Pine and your rival Braydon (no Oak or Tracey though). Pine will ask you and Brayden for some help with his research. However, once the three of you enter the mountain’s caves, you’ll find Cosmo and Team Planetary hunting for the Cosmic Guardian and the Grand Meteoric Shard. I’ll tell the rest of the story in the next episode’s review, as not to spoil the next episode.
On a different train of thought, probably the biggest thing to come from this episode besides Team Planetary is Tracey. I know I’ve been bringing back a lot of older characters lately, but Tracey is different. The others were only recurring characters, Tracey was a main character. Tracey’s reappearance is an attempt by me to fix what is in my opinion one of the worst mistakes made by the show: a lack of continuity. It bugs me to no end that characters such as Tracey who played in important role in Pokémon’s history just get discarded and forgotten. If Pokémon really wanted to be a better series, it would embrace its past as well as move towards the future.
