To put it simply, this reason opens a lot of doors to the series. It means that there's a possibility that more humans can become Zyuohgers if they were given the right conditions to become one. It means that Yamato is not the only special human being who can do so if this plot element is done properly. As for the heartbreaking side of things, it gives a whole new meaning on how the bird-man saved Yamato in the first episode. If you look at it, there is a possibility that the bird-man died because he sacrificed some of his zyuman power to a human being. It didn't help that it's been over a decade since Yamato saw him. Add that possibility, we get a very down Yamato in this episode.
Before I start to forget about it, the player's plot is to eat everything. That's it. It's pretty standard for a ridiculous monster of the week, but hey, if it ain't broke, don't fix it. The only thing worth noting about the player's return is that we learned that Azald has the ability to regenerate his body. Since his player is alive, there's no need for him to stay on Earth and leaves. Well that's a waste of a good Joji Nakata.
Back to the plot of the episode, Yamato is still down on what he found out and because of this, Larri decides to comfort him by giving him assurance that what he did for Yamato is the right thing. What I love about this scene is the exchange between the two. We see Yamato feeling guilt that his injuries led to Larri giving away some of his power. Larri's response is something that I already expected. Yamato renewed his faith on humanity. Yamato made him realize that not all humans are that bad and as seen earlier in the episode, when Larri saved the little girl, instead of her running away, she hugged Larri and thanked him.
More on Zyuoh Gorilla in this episode, they explored more of his fight style. We see him swing around, throw fast punches and overall, use his brute strength to dislocate the jaw of the player. What's interesting about Zyuoh Gorilla is that it seems that he doesn't have his own Beast Unleashed mode, and I am okay with it. I mean, the large muscles alone speaks a lot on what animal Yamato is representing at the moment, which is the job of the Beast Unleashed mode, to show off the trait of each animal.
Cube Gorilla's debut is amazing. Not only we see him do the things we expect a gorilla will do such as swing around in some kind of a circus rope (?) and pound the player to a pulp, we also see yet another creative use of the Cube Animals' cube form as Cube Gorilla used it to break the player's jaw. It's funny and it showed us that there are unlimited possibilities when it comes to the use of the Cube Animals' cube form in battle. Now that they are done showing off Cube Gorilla, it is time for the wild debut.
As for the mecha's finisher, it is a barrage of rocket punches. The idea in itself is amazing, but as for the execution, it felt lackluster. I get that you got a cube motif going on, but please, there's another way to show it. The way the finisher was shown in the episode felt like the purpose of the punches is just to form boxes on the player. The finisher will look better if the execution was a barrage of punches hitting multiple targets in rapid succession, which then creates the three boxes. It looks flashy and something that I can easily get behind.
The episode ends and Larri decides to leave town for good so that he can explore and see the human world from a different perspective. Good luck with that one Larri, and we hope to see you more in the future!
