The Shane Gang assault Dr. Blakk's stronghold while Pronto is given the mission to contact the Shadow Clan in order to repel
Dr. Blakk and the Darkbane once and for all. When Eli, Trixe, and Kord arrive they find Blakk and his goons waiting outside. Eli charges in to destroy the Terraportal but already finds it active and is forced to duel Blakk one on one while Trixe and Kord duel everyone else outside. However the gangs blasters can only handle MegaMorph energy before a cooldown and suffer defeat due to Blakk and the Barkbane not having this handicap for some reason. Nacho damages Kord's Mechabeast causing him to go in a rage resulting in a brawl, leaving Trixe to duel the rest of the Darkbane alone. Meanwhile Eli gets shot through a wall and separated from his accelerator upgrade. He responds with a Fusion Shot that miraculously defeats a Megamorph however the Terraportal is almost finished. Trixe loses her blaster and is forced to use Kord's and literally gets knocked off her feet due to the recoil. Pronto arrives with the Shadow Clan, defeats the Darkbane and everyone charges into the portal room for a last stand. The portal is finally complete and the Darkbane army teleports through. In the battle Pronto remembers that he also brought Doc (the healer slug last seen in "What Lies Beneath") as well and Eli uses him to shut down the machine. Doc's powers actually puts the machine in reverse sucking all of the Darkbane back to the Deep Caverns and Eli and Blakk get sucked in as well. The Shadow Clan Leader attempts to shut down the portal by jamming the gears while Eli and Blakk continue fighting on the trip down. Eli escapes riding on Burpy and the Shadow Clan thank the Shane Gang for stopping the Darkbane. The episode closes at the Drop to the Surface where the gang think Eli is leaving but instead he uses Burpy to seal the entrance just before Blite appears riding on a dinosaur.
