After they defeated the player and since he is still alive, our heroes looked for him, only to find Larri, a zyuman living in the human world. Larri is awesome; he's a gorilla who likes to speak Spanish phrases and is seriously friendly. He is that kind of guy you want to have tea with because he's that approachable. As for how he ended up in the human world, turns out that he's a scientist whose job is to study humans... which is not a surprise considering that we study animals to better understand them. The reason why he's stuck here is because of a missing Champion Symbol. You know, the one Yamato have since he was a kid given to him by the Bird Zyuman? This is one nice piece of continuity and it makes me wonder if there are any other zyumans who were stuck in our world since then.
Of course humans will be afraid of something that they didn't expect to see in the city! I mean, a gorilla that knows how to speak Japanese and likes to spout Spanish phrases from time to time? I will be really afraid of that! What makes this scene great later in the episode is how the zyuman Zyuohgers compared this to their first encounter with Yamato. They think that he's harmful because he is human. It was until they befriended him when they find out that he's a really great guy. That being said, Yamato, with the help of his friends tries to befriend Larri.
He was beaten so badly that he suffered a lot of injuries. Seeing Yamato's desire to protect anyone, it opened Larri's heart and decided to give him some of his zyuman power to hasten up his healing. Now fully healed, Yamato continues his fight against Azald! Much to his surprised, he gets a strength upgrade and transforms into Zyuoh Gorilla by lifting his visor up! The transformation into Zyuoh Gorilla is interesting. I mean, lifting a visor to become a new Zyuohger? That's something new. For most of the time they'll do something with the transformation device to transform into a new form. But in this case, they cut the middle man and just went straight to the new helmet.
