Episode 37 begins with the Gokaigers defeating giant sized Sgormin. After the battle, Machalchon asks the Gokaigers what their "ultimate power" is, which the Gokaigers are unable to answer. Later on, Gai and Marvelous have a conversation about protecting Earth. When Gai asks Marvelous "What do we have to do to protect it?" Marvelous walks off, saying he doesn't know. Meanwhile, the Zangyack emperor sends a new weapon for Walz Gils, the Great Walz robot. Walz Gils also argues with Damaras, and reveals through a flashback that he knew his father had sent Damaras to babysit him. Barizorg shows his loyalty to Walz Gils by pledging to fight by his side. While Gai and Joe are having a conversation on deck, they're attack by Barizorg and the Gormin. Joe tells the other Gokaigers he'll take care of Barizorg, while the rest fight the Gormin. While Barizorg and Joe fight, the other Gokaigers are attacked by the Dogormin, who are much more powerful than the Gormin. The Gokaigers then transform into various extra heroes for the first time (BullBlack, Zubaan, DekaSwan, WolzardFire, and Signalman), and force the Dogormin to retreat. The Barizorg-Joe fight ends in a draw, when Walz Gils shows up with the Great Walz. The Gokaiger's mecha arsenal is overwhlemed byh Great Walz, so they try GoZyu-GokaiOh, but it also fails against the Great Walz. The Great Walz is about to obliterate GoZyu-GokaiOh when Marvelous uses his captain rank to eject the other Gokaigers. They're spread throughout town, and episode 37 ends with Marvelous lying unconcious inside the cockpit of Gokai Galleon.
Episode 38 picks up with Walz Gils sending Barizorg and the gormin to search for the Gokaigers and finish them off. Luka, Ahim, and Don are able to avoid the gormin, and run into Gai. Gai says he can't except what Marvelous did, and wants to be a crew instead of him trying to protect them. Meanwhile, Joe runs into Barizorg and defeats him. Meanwhile, Marvelous seemingly in the afterlife, is met by AkaRed who tells him that the Gokaigers rather have him protect their friendship to pursue their dreams instead of protecting them. Joe has a similar experience, seemingly meeting Cid Bamick in his conscious. Cid tells Joe to go meet up with his friends. While Joe leaves, Marvelous wakes up to search for everyone. Joe catches up with the others, who are confronted by the Sgormin. Marvelous shows up and tells them that he realizes their dreams aren't fragile enough that he should worry about protecting them. Meanwhile, Joe tells Marvelous that it gave him the opportunity to take care of unfinished business. The Gokaigers transform and defeat the Dogormin and the Sugormin. Walz Gils shows up in Great Walz, trying to avenge Barizorg's death. However, the Gokaigers are able to unlock their own ultimate power and form Kanzen GokaiOh. The Gokaigers proceeded to defeat Walz Gils. At the end of the episode, Damaras carries Walz Gils' corpse and curses at the Gokaigers.
This two parter, along with the movie (which I'll review within the next week) really gave me a new perspective on Gokaiger. When I first started viewing Gokaiger, I was really excited about the show with all the likable cast and the tributes to all the past sentai teams. As the series progressed, I thought it was starting to lose a little steam. The show has never been bad, and in fact I've always enjoyed the cast and the majority of the episodes. However, what had been a letdown were the villains, save for Basco and to an extent, Barizorg for how his story relates to Joe. I felt that the Zangyack main villains were always underused, and Walz Gils was overly stupid. Overall, I thought the Zangyack were among the weakest villains of the last decade. However, this episod gave some really good depth to the villains, particularly Walz Gils, Damaras, and Barizorg. After watching this two parter, I realized the Zangyack are support characters, and as long as you know when to use the villains, you don't always need strong villains to have a great show. It showed Walz Gils in a new light, struggling to prove himself among the Zangyack ranks. When I looked back, Walz Gils in the last 11 or 12 episodes he appeared in, did have a few competent plans. I also like how Barizorg was used as both a support character to Joe (because of the backstory) and to Walz Gils (because of his loyalty to him). This two-parter also showed Damaras in a new light. One that has a responsibility to protect Walz Gils, the Emperor's son, and shows the emotional attachment he has to Walz Gils. This two-parter doesn't fully redeem the Zangyack. I'm still mixed on them as a whole, and it's still hard to ignore Walz Gils' 30+ episodes of incompetence. I also wish they explored the Damaras-Walz Gils relationship earlier in the series. However, it gives me hope that by the end of the series that the Zangyack could be respectable. The show still has Basco, one of the better villains over the last decade. Damaras I believe can get interesting, and we still haven't seen the emperor yet. Besides the development for the villains, I also enjoyed the story and the character development for Marvelous, Joe, and Gai respectively. There were still a couple mild complaints that I have about it. One being how easily Joe's suit was reflecting Barizorg's attacks, and the other being the underwhelming finishing move that Kanzen GokaiOh has. However, these flaws have no weight on the story as a whole, so I'll let them slide. I'm giving this two-parter a rare perfect rating of 10/10. I loved this two-parter so much, and believe it's the best plot in Gokaiger so far.
