Ralphie - the greatest Pokemon rival to ever live - has not given up on his quest to take on Red. The only problem is that Red doesn't remember him, he's unemployed, and his only Pokemon is a near-death Metapod. Other than that, Ralphie's on the path to glory!
Ralphie's back! And he's got Red's son, Todd (who's still alive, by the way). Now all he needs is to catch up on the past 20 years of Pokemon, figure out how to catch and train new Pokemon, and actually put together a team to defeat Red. That's it!
