Episodes

 * 1) TbD - Whilst calmly walking to school for their first day of their senior year at high school, the fiery Drew McArthur, the calm and reserved Kiana Young, and the fun-loving Luke Herrera encounter a fairy named Inkie, who leaves behind a book. As Anabelle has trouble introducing herself to the class, Drew helps her break the ice. As Drew, Kiana and Luke check out the library later that day, they discover a mysterious entrance, taking them to a strange place where they learn Inkie is being chased by [Name of Villain General 1], who starts making the people in the town fall into despair and steals their 'bad energy' with a goal of resurrecting an evil emperor named Zeron. As Drew, Kiana and Luke strive to protect Inkie, they are given their very own Wonder Ride Books and Holy Blades, using them to transform into Power Riders Pyrus, Aquos and Dendrus respectively. [Name of Villain General 1] summons a monster known as a [Name of Monster] to fight against them, but with help from Inkie, Drew and his friends manage to realize their power and defeat it, receiving another Wonder Ride Book in the process. As [Name of Villain General 1] retreats and happiness returns to the townspeople, Drew and his friends decide to help Inkie in her quest to recover Wonder Ride Books and save her kingdom.
 * 2) TbD - After hearing from Inkie that they need to gather four more Riders, Drew, Kiana and Luke mention it to Ethan Ross and his other classmate, Anabelle Park, though Ethan turns down the idea to focus on his baseball. Later that day, Luke notices Ethan downhearted over a baseball slump, so he decides to help him practice. However, during Ethan's baseball game the next day, Wolfrun appears to steal their bad energy, creating a baseball monster. Drew and co. transforms to fight against it but Ethan loses energy when his finishing attack misses. When Ethan realizes Drew and co. is in trouble, he overcomes his despair and stands up to the monster, gaining the power to transform into Power Rider Electros and defeat the monster. Afterwards, Drew, Kiana, Luke and Ethan decide to become good friends.
 * 3) TbD - Having taken notice of her drawing talent, Drew and his friends nominate Anabelle to design a poster for a school contest. Anabelle herself doesn't have much confidence in her ability, but Drew and Kiana encourage her to give it a try and agree to help. Anabelle eventually manages to finish the poster, but becomes downhearted when it doesn't win, making her a target for another villain, [Name of Villain General 2], who makes a [Name of Monster] from Anabelle's poster. As Drew and his friends end up exhausting themselves too early and struggle to fight against the monster, Anabelle overcomes her fears and stands to protect them, gaining the power to become Power Rider Ventus.
 * 4) TbD - Impressed by her courage whilst standing up to some upperclassmen, Drew sees Bryce Clayton as a potential Power Rider candidate. Wanting to get a chance to invite her to join, Drew ends up joining Nao to her home, where he meets his large family of siblings. As Kiana, Luke, Ethan and Anabelle join them to play some games, [Name of Villain General 2] appears, making Bryce and his family miserable and creating a monster who takes Drew as hostage and targets Bryce's family. As Bryce becomes determined to protect his family, he gains the power to become Power Rider Geos and defeats the [Name of Monster].
 * 5) TbD - With one more Power Rider to find, Kiana decides it should be the student council vice president, Justin Zhao. However, Justin rejects the offer as he is busy preparing for the upcoming homecoming dance as the president is absent with a cold. Drew and the others decide to help him out. However, during the dance, [Name of Villain General 3] appears and creates a Mirror [Name of Monster] which clones itself, causing the Riders to waste their power. Eventually, Justin stands against her and becomes Power Rider Cryos, figuring out who the real [Name of Monster] is and defeating it. After finishing up the show, Justin accepts the offer of becoming friends of Drew, Kiana, Luke, Ethan, Anabelle, and Bryce.
 * 6) TbD - The gang is visited by Inkie's older brother, Morphos, who takes them to the mysterious library Drew, Kiana and Luke discovered before. He then proceeds to explain about his homeland, the Wonder Realm, was invaded by Zeron, who stole the Wonder Ride Books, sealing them away in the capsules used to summon [Name of Monster]s. Using the last of his strength, the King of the Wonder Realm sealed Zeron away, requiring the Wonder Ride Books to be restored. Suddenly Majorina appears to cause trouble in the park, and the teens teleport to the location. As [Name of Villain General 3] brings out a drink can-themed [Name of Monster], Morphos transforms into a giant can crusher to help the Riders defeat the [Name of Monster]. Afterwards, Morphos returns to the Wonder Realm, leaving behind the Wonder Ride Library to store the Wonder Ride Books.

Unable to figure out how to get the rings off, Drew and Luke have to fill in for each other during classes. Eventually, Drew and Luke get into a very big argument, and [Name of Villain General 3] then creates a [Name of Monster] from a playground ride which proves too fast for the other Riders to handle. As Drew (in Luke's body) stands to defend Luke (in Drew's body), they apologize and manages to become their Rider forms (Drew in Luke's body becoming Power Rider Pyrus, and Luke in Drew's body becoming Power Rider Dendrus), defeating the monster whilst the others manage to retrieve a potion from [Name of Villain General 3] to remove the rings and return Drew and Luke back to normal.
