Plawres Sanshiro (プラレス3四郎, Puraresu Sanshirō) is a Japanese manga series written and illustrated by Jirō Gyū.

The name is a shortened derivative of "Plastic Model Wrestling Sanshiro" and the visuals of the characters, in particular the PlaWrestler robots, were different from the manga.

[citation needed] As the series went on, its focus shifted to Sanshiro exploring the possible uses of PlaWrestling technology in medical implants, and his clash against those who wished to use it for military purposes instead.

Tetsuya is Juohmaru's mechanic, responsible for fine tuning him, upgrading him and repairing him, especially during the minute-long break between a battle's rounds.

He is shown to be very capable, a quick thinker and an innovator, although at times he has taken offence at Sanshiro overriding him for Juohmaru's maintenance.

For the most part, Kennosuke is critical of Sanshiro's PlaWrestling exploits, preferring him to practice judo and eventually succeed him as dojo master instead.

José Garcia is a ruthless arms dealer who manipulates the PlaWrestling scene worldwide by funding and essentially bribing its officials.

He actually manages to develop and market robot soldiers of questionable competence, and Sanshiro believes in allowing the world to judge for itself whether the peaceful or aggressive use of PlaWrestling technology is more useful.

Ballesteros is a self-important man who manipulates the Association, its Japanese branch (JPWA) and the Fighting-type Modeler League to further Garcia's ends.

After Garcia develops his robot soldiers, he loses interest in PlaWrestling and cuts funding, leading an enraged Ballesteros to face off against Sanshiro in the series finale.

An enigmatic, beautiful woman riding a motorbike, Shiela spies on Sanshiro from the first episode and constantly manipulates events and people to force him to give up PlaWrestling.

However, he loses from Sanshiro in the first episode, partly due to damage his PlaWrestler, Mad Hurricane, sustained during the championship match.

Narita is down-to-earth, intelligent, collected and has the respect of Sanshiro and his team, but his attitude sometimes makes him take things too seriously and appear cold and distant.

Dr. Warmer analyses this data and eventually comes up with a novel technology that relies on brain wave induction to restore a person's mobility.
