Pokemon Adventures: Yellow

This Arc focuses mainly on Yellow, a young trainer from viridian city.

after Red's defeat by Bruno of the Elite 4 and subsequent disappearance, yellow sets out to find him, and return Pika to him.

after a long journey around the Kanto region, a training session with Green and a Team-up with several gymleaders, the story shifts to the Cerise island, far south of kanto, where the final battles with Lance and the Elite 4 takes place.
Blue gets another chance to show off how Crazy-Prepared she is against Lorelei. Koga gets to show how Freaking HardCore he is, and Red saves Bill's and Lt.Surge's asses from getting melted. Yellow fares less well, as it takes not only Mewtwo softening Lance's Pokemon up, as well as mass Evolutions, to turn the tide of the battle

Ultimately, It's revealed that Pikachu knew all along what Lance had planned, and, with power from Venusaur, Charizard and Blastoise, uses the accumulated energy to reverse the environmental damage shown through-out the Arc, rather than commit human Genocide as Lance had planned.

all in all, a Very Good Chapter.
