Ash has finally arrived in Driftveil City for his next Gym battle. However, when they meet Gym Leader Clay, he informs our heroes that he’s too busy at the moment, so Ash and friends decide to hang out until he’s ready. They meet a friendly motorcycle rider named Charles, who offers to show our heroes around town, starting with the famous Driftveil Market. Everyone there knows Charles and his Accelgor, and our heroes are treated to lots of delicious food!

When a thief targets one of the market’s shopkeepers, Ash tries to stop him, but is interrupted by the sudden arrival of a masked hero: The Mighty Accelguard! What Ash and the others don’t know—yet—is that The Mighty Accelguard is actually their new friend Charles in disguise. Charles and his Accelgor try to go after the thief, but when his motorcycle runs out of gas, it’s up to his friend Linda and her powerful Timburr to catch the crook!

Linda knows all about Charles’s secret identity, and isn’t too impressed—but Ash thinks The Mighty Accelguard is the coolest, and really wants a chance to meet his awesome Accelgor in person. Charles hints to Ash that he might want to stop by the warehouse district that evening...

It seems there’s been a rash of break-ins around the warehouse district recently, and Charles and Linda have both noticed a suspicious truck in the area. Linda goes to investigate and is confronted by the nefarious Team Vanillite, whose plan is to steal all the frozen food from the cold storage warehouses and give it to hungry wild Pokémon, thus gaining their loyalty and using their power to take over the whole Unova region!

It looks like Linda is in a bad spot—but once again it’s The Mighty Accelguard to the rescue, this time with our heroes helping out! Together, they manage to defeat Team Vanillite and drive them away, securing The Mighty Accelguard’s title as the hero of Driftveil City!
