Guyferd tells the story of Gou Kazama, a martial artist who comes back to Japan after traveling the world to find his missing brother Masato. He is soon captured by the evil organization Crown and is changed into the Guyferd, a combination of cybenetic implants and an alien parasite, giving him new found power. Gou is aided by Doctor Yakeo Shiroishi, fellow martial artist and rich girl Rei Kujou and her little brother and hacker Yuu. Gou uses his fighting skills to fight Crown and their legion of cyborgs and mutants, protect his friends, and search for Masato while attempting to control the Guyferd power.
Though it borrows heavily from other toku series before it, what makes Guyferd stand out are its use of martial arts and well done choreography, making for a very unique Fighting Series.
This show provides examples of:
- Alas, Poor Villain: In episode 15, it is revealed that Shion's mother died because of a defective medicine (among 198 victims) and that she wants to take revenge against the owner of the pharmaceutical company which created the medicine (not to mention that said owner managed to escape justice and always act as a complete asshole). And unless you consider a punch in the face to be an appropriate punishment for him, this is also a case of Karma Houdini.
- Applied Phlebotinum: The Fallah parasite.
- Fighting Series
- Henshin Hero
- Heroic Sacrifice: Gou and Masato in the final episode.
- Homage: Guyferd shares a similar origin to Kamen Rider, has a similar name to and elements from Guyver, and looks a lot like a semi-organic Ultraman.
- Ki Attacks: All of the Mutians were former martial artists, and possess the ability to throw fireballs.
- Mecha-Mooks: The Guyborgs and Fangs.
- Monster of the Week
- Ninja Pirate Zombie Robot: The main character started out as a professional martial artist, wound up getting infected with the stuff that turns most people into Mutians while managing to enter a symbiotic relationship with it, then got turned into a cyborg. In other words, he qualifies.
- People in Rubber Suits
- Phlebotinum Rebel: Just like what it inspired it. Gou was meant to be one of Crown's soldiers.
- Shock and Awe and Whip It Good: Volgis.
- Shout-Out: Even though the way they got their powers were different, the way Gou had to train in martial arts to learn how to transform is very similar to the How Do I Shot Web? dilemma that the protagonist of Kamen Rider Super-1 faced in his series.
- Transformation Sequence: It uses Conspicuous CG for the sequence.
- Tsundere: Rei.
