Brave 13: Digging! My Treasure
Using her Joyful Song, Poisandra lured a group of men with the allure of treasure as Wrench arrives and learns it is a ploy for her plan to gather happiness from her arranged treasure hunt. At that time, with only use of the Dino Armor X (Deinosuchus) Charger unaccounted for, the Rangers arrive and thwart Poisandra's plan. After getting the people to safety, with Wrench noticing Tyler's pendant, the Rangers fight Poisandra's Monster, Zaihon, as Wrench joins the fray to have Dino Charge Red to himself so he can have his pendant.
As Dino Charge Gold arrives to give their teammates an advantage on Zaihon, Dino Charge Black finds Tyler being held by Wrench as he compared the youth's pendant to his prized jewel: the jewel that Chase and Isabelle searched for. Upon learning that Wrench is the one who killed Isabelle and not Doronbosu, a furious Kyoryu Black attacks the knight with extreme prejudice before Zaihon arrives and buries Tyler, Dino Charge Pink, and Dino Charge Gold under his stone slabs. Using the Dino Helio (Fukuiraptor ) Charger on Dino Charge Blue, the three Rangers return to the Spirit Base to regroup before planning the rescue of their teammates.
However, fearing he would lose his cool again, Chase decides to stay back for a bit. As he tells Koda and Torin go ahead of him, Riley tells Ian that they will wait for him. Knowing what to do, as Dino Charge Blue, Dino Charge Green, and Torin deal with Zaihon and Luckyuro, Dino Charge Black arrives with the Dino Armor X Charger and attempts to use it. Though it failed as Wrench attacks him, Dino Charge Black learns he can use the Dino Armor X Charger with his Armed Mode and uses it to assumed Dino Armor X Mode force his way through the villains before breaking through the slabs and getting his teammates out.
Confirming Daigo's pendant and his jewel are linked, Wrench loses his treasure to Dino Charge Green as Daigo transforms to join his team in defeating Zaihon with a Dino Spike/Dino Armor X combo. Enlarged by Luckyuro, Zaihon overwhelms Dino Charge Megazord and Ptera Charge Megazord before they combine Raiden Dino Charge Megazord to finish the Debo Monster off.
As the Rangers ponder on the relation between Tyler's pendant and Chase's gemstone, Torin is sure that they will learn the full story of the past.
