Gorgom's plot in this episode is something that I really like. They used the three men that they recruited to kill evil humans. Since this is Gorgom we are talking about, I am pretty sure that it will start with killing regular evil humans and slowly, Gorgom will order them to kill specific humans that will harm the organization. It's wise and I love that Gorgom is training humans to become assassins that will cause the extinction of humans. But what stole the show is the appearance of the Rhinoceros Mutant.
What made it sweeter is that we also learned that Battle Hopper has the ability to regenerate, a unique feature that I wish other Rider Machines have. The regeneration scene showed us that Battle Hopper is part organic and part machine. Organic in a sense that it feels like he is regenerating dead muscles and dead skin cells thanks to the beautiful use of special effects to make it look that. But the best part about the regeneration scene? Kotaro's reaction after discovering that Battle Hopper can regenerate itself; it is like seeing a master happy that his favorite dog is alive and doing well. That is why my friends, is the reason why love Battle Hopper.
The fight between BLACK and the Rhinoceros Mutant is really amazing. Fighting him in an abandoned warehouse first just to measure his abilities is really smart as it made him figure out his major offensive tactic. What's more, after he figured it out, he dispatched it to weaken it. Even though he dispatched the mutant's strongest weapon, its raw power is enough to destroy steel towers. But BLACK is strong enough to get out of the ruble and also, he has some help from Battle Hopper! Thanks to Battle Hopper, he was able to disable the mutant before finishing it off with a Rider Kick. At the end, the guy that Kotaro saved is now out of the hospital and learned the error of his ways. What a great way to end the episode!
